Here Comes the SCAPP Bot!

Editor’s Note: Here is a second post by/for Dr. Alexandra Ratzlaff. Alex has been working with the Brandeis Techne Group as Residents at the Autodesk Technology Center and in partnership with the Brandeis MakerLab run by Brandeis’ very own Ian Roy. They have some pretty amazing work to feature.

The overarching aim of the Brandeis Techne Group as Residents at the Autodesk Technology Center in Boston is to develop new equipment and methodologies to help push forward the collaboration between technology and the humanities. With a focus on archaeological research and applications, this group seeks to develop new ways of analyzing the material culture of the ancient and historical world. The initial goal of our project is to fabricate a prototype ‘Single Camera Automated Photogrammetry Platform’ (SCAPP) with the final designs and methodology available for reproduction through an open-source platform. The SCAPP is intended to be relatively low-cost and easily reproduced as an alternative to other digital imaging equipment.

Archaeologists tend to be technological and equipment scavengers, often looking to related fields for ways to gather data and perform an array of methods of object analysis. The advantage of this is that it is a process and environment that breeds innovation. It is easy to work outside the box when you have very few limitations. This spirit of innovation is what drives our Techne Group.

After being initially approached by a member of the Autodesk team at the Boston Technology Center, Alexandra considered how to combine her interests in technology with archaeological field methods. With over 15 years of experience excavating, she recognized the importance of new technological applications used in digital imaging, mapping, and site virtual reality among other areas. The Autodesk Technology Center presented an opportunity to not only develop new equipment to be used in excavation and lab analysis but also a means towards further bridging the gap between the humanities and technology. A partnership with Autodesk and Brandeis also would have the potential to be used as a learning experience for students and a way to experience the humanities through a completely new lens.

After spending months negotiating a contract between the two institutions, Alex then had to build a team. Having met Ian Roy the previous year, Alexandra considered his background in digital applications, imaging, and 3D workflows particularly relevant and ideal as a potential team partner. Ian’s extensive background in 3D scanning, photogrammetry, and photography, as well as participation in archaeological excavations in Greece as a technology director and specialist, all complimenting the potential collaboration with Alexandra and the Autodesk team. In an effort to make the Autodesk team a beneficial learning experience for students, Alexandra selected a graduate and undergraduate student from the Department of Classical Studies to join the team. Erin Brantmayer (MA 18’) and Helen Wong (BA 19’) contributed years of archaeological excavation experience as well as Erin’s previous work with field photogrammetry and Helen’s comprehensive work with 3D scanning provided the team with a variety of skill sets.

In an initial meeting with the early team members, numerous ideas were proposed in how to effectively integrate new forms of technology into archaeological methodology and what current applications could be further modified and improved upon? Ian showed the group the research of Professor Duncan Irschick’s “BEAST Cam”, a photogrammetry rig that employs approximately forty dSLR cameras to capture image datasets. This methodology produces high-quality images and models; however, the equipment is far too cumbersome for archaeological fieldwork and impractical for budgets as well. Ian’s suggestion inspired the group to focus on digital imaging. This resonated with archaeologists, Alexandra noted that a current problem in archaeology is obtaining high quality photogrammetry of artifacts as they are found in the ground before removal, in which some fragile artifacts sometimes further deteriorate. From this conversation, the idea emerged to develop and fabricate a new type of photogrammetry equipment that would incorporate the group’s interests and expertise.

However, it was evident that any development of equipment would require the input of a professional engineer. Ian proposed another member of the Brandeis RTI team, Tim Hebert, the Embedded Systems and Robotics Specialist and head of the Automation Lab in the Brandeis Library. Tim and Ian had worked together since 2013 as part of the team that founded the MakerLab at Brandeis. Tim contributes a background in embedded systems engineering and mechanical logic, as well as meticulous CAD design with Fusion 360. Together the initial group began their residency at Autodesk in the winter of 2018. Alex took the role of Team Lead and Principle Investigator, Ian took the role of Head of Method, Workflow & Planning, and Tim took the role of Head of Engineering and Design.

In archaeology we are constantly seeking new technological applications to field and survey research. However, very seldom is any of the equipment or software we use specifically designed for archaeology. Recording architecture and artifacts is a cornerstone in archaeological methodology, any developments in this area can become vital for the preservation and interpretation of a site or assemblage of artifacts. This was the broad problem identified by the group, further focusing on the development of equipment that could be used in the field and laboratory on objects that are highly specular or unsuitable for structured light scanning.

The SCAPP resolves these issues as a relatively light-weight and portable automated rig for a single camera. The design helps to rectify another issue faced by archaeologists in the field, which is how to perform photogrammetry on small object before they are removed in excavation. Some artifacts can be extremely fragile, such as glass or metal, the SCAPP is specifically designed to be put over an artifact to collect a photogrammetry dataset before the artifact is ultimately removed in excavation. If it is too fragile and further deteriorates while being removed at least a partial or full 3D model can be created from the SCAPP data. It also allows consistent and repeatable results. Our goal in the Techne Group is to “Science the past” – so much photogrammetry is based on artistic decisions, we want to “science” this problem. We have found that by normalizing our data acquisition, we can be agnostic about our processing methodology: cleaner data results in cleaner renders regardless of the software used.

 

The Techne group is truly a product of multi-disciplinary experiences and approaches to problem-solving. As our group keeps refining the capabilities of the SCAPP we will look at other issues facing archaeology in the realm of digital imaging and reconstruction.

The Process: What is a SCAPP bot?

Design and fabrication of an automated gantry system to move a dSLR camera in a full circuit around an object in order to take 30-100 + photos as datasets processed in photogrammetry software. The output generated through these programs provides a scale and color accurate 3D model, best for objects with high secularity.

  •  The initial prototype was constructed in birch to test the perimeters of camera angles and the feasibility of the geared frame and arch system.
  •     In the second incarnation of the SCAPP the entire frame was cut from aluminum using the Autodesk waterjet; carriages were printed in PLA and Markforged; and a computer from an industry standard “Ramps board” – the materials were chosen for their accessibility and relatively low cost.
  •     The SCAPP operates essentially as if it were a 3D printer, it uses a printer control board and motors, but moves and actuates a DSLR or phone).
  •     SCAPP can also function as a non-automated circular tripod in which data acquisition can be done manually while maintaining the leveled set degree position of the camera. 

SCAP Prototype

The Fieldwork

Designed as a portable imaging tool, SCAPP testing has included laboratory settings such as those at Autodesk, the classroom, and at an archaeological excavation. Initial SCAPP field testing was carried out in the summer of 2019 at Tel Kabri (israel) by Alexandra Ratzlaff and Erin Brantmayer of the Brandeis Techne Group.

While data was collected in the field, team members Ian Roy, Tim Hebert, and Daniel Lay developed an updated version of the SCAPP based on feedback from field and continued lab testing. Currently, the group is continuing to improve and refine the engineering and design of the SCAPP through collection of data sets primarily on artifacts from the Brandeis CLARC (Classical Artifact Research Collection). 

The Future

In archaeology we are constantly seeking new technological applications to field and survey research. However, very seldom is any of the equipment or software we use specifically designed for archaeology. Recording architecture and artifacts is a cornerstone in archaeological methodology, any developments in this area can become vital for the preservation and interpretation of a site or assemblage of artifacts.

A Healthy Mind in A Healthy Body, but Greek

Xenophon, Memorabilia 3.12

“For all of the uses of the body it makes a big difference to keep it in as good a condition as possible. Even for thinking, in which the use of the body seems least important, who does not know that many things fail in its practice because the body is not healthy? Forgetfulness, depression, ill temper and madness often strike the mind so badly because of bodily afflictions that it drives out understanding.

There is great stability for those who have strong bodies and there is, at least, no danger from suffering something like this because of physical affliction. No, it is likely that the useful help will develop as the opposite to those things that happen from affliction. And, indeed, what wouldn’t someone who has some sense try to forestall the opposite to those things I have mentioned?”

πάσαις δὲ ταῖς τοῦ σώματος χρείαις πολὺ διαφέρει ὡς βέλτιστα τὸ σῶμα ἔχειν· 6ἐπεὶ καὶ ἐν ᾧ δοκεῖς ἐλαχίστην σώματος χρείαν εἶναι, ἐν τῷ διανοεῖσθαι, τίς οὐκ οἶδεν, ὅτι καὶ ἐν τούτῳ πολλοὶ μεγάλα σφάλλονται διὰ τὸ μὴ ὑγιαίνειν τὸ σῶμα; καὶ λήθη δὲ καὶ ἀθυμία καὶ δυσκολία καὶ μανία πολλάκις πολλοῖς διὰ τὴν τοῦ σώματος καχεξίαν εἰς τὴν διάνοιαν ἐμπίπτουσιν οὕτως, ὥστε καὶ τὰς ἐπιστήμας ἐκβάλλειν. 7τοῖς δὲ τὰ σώματα εὖ ἔχουσι πολλὴ ἀσφάλεια καὶ οὐδεὶς κίνδυνος διά γε τὴν τοῦ σώματος καχεξίαν τοιοῦτόν τι παθεῖν, εἰκὸς δὲ μᾶλλον πρὸς τὰ ἐναντία τῶν διὰ τὴν καχεξίαν γιγνομένων τὴν εὐεξίαν χρήσιμον εἶναι. καίτοι τῶν γε τοῖς εἰρημένοις ἐναντίων ἕνεκα τί οὐκ ἄν τις νοῦν ἔχων ὑπομείνειεν;

 

Xenophon elaborates on some of this earlier

Xenophon, Memorabilia 3.5

“Certainly it is necessary—since the city does not provide public expenses for war—not to overlook it privately, nor otherwise to care for yourself less. Know well that you be no worse off in any other struggle or action because you have put your body in better shape. For the body is useful in everything people do. In all functions of the body it makes a big difference that the body is as healthy as possible. Even in something you might think the body is of little use—thinking—who doesn’t know that great errors come from having a sick body?

Forgetfulness, loss of spirit, ill-temper and madness often impinge upon perception because of the weakness of the body so badly that all knowledge is expelled. But for those who are healthy in body it is a great protection and they suffer no suffer no such risk of suffering this kind of thing because of the weakness of their body. It is probably that for those who have a healthy condition they will have the opposite experience. And, certainly, won’t anyone with some sense endure anything for the opposite of these things that have been mentioned?”

Anyway, is it not shameful to grow old because of carelessness before seeing how beautiful and strong a person you might be thanks to your body? It is not possible to witness this for someone who doesn’t make an effort. For it is not willing to develop on its own.”

Οὔτοι χρὴ ὅτι ἡ πόλις οὐκ ἀσκεῖ δημοσίᾳ τὰ πρὸς τὸν πόλεμον, διὰ τοῦτο καὶ ἰδίᾳ ἀμελεῖν, ἀλλὰ μηδὲν ἧττον ἐπιμελεῖσθαι. εὖ γὰρ ἴσθι, ὅτι οὐδὲ ἐν ἄλλῳ οὐδενὶ ἀγῶνι οὐδὲ ἐν πράξει οὐδεμιᾷ μεῖον ἕξεις διὰ τὸ βέλτιον τὸ σῶμα παρεσκευάσθαι· πρὸς πάντα γάρ, ὅσα πράττουσιν ἄνθρωποι, χρήσιμον τὸ σῶμά ἐστιν· ἐν πάσαις δὲ ταῖς τοῦ σώματος χρείαις πολὺ διαφέρει ὡς βέλτιστα τὸ σῶμα ἔχειν· ἐπεὶ καὶ ἐν ᾧ δοκεῖς ἐλαχίστην σώματος χρείαν εἶναι, ἐν τῷ διανοεῖσθαι, τίς οὐκ οἶδεν, ὅτι καὶ ἐν τούτῳ πολλοὶ μεγάλα σφάλλονται διὰ τὸ μὴ ὑγιαίνειν τὸ σῶμα; καὶ λήθη δὲ καὶ ἀθυμία καὶ δυσκολία καὶ μανία πολλάκις πολλοῖς διὰ τὴν τοῦ σώματος καχεξίαν εἰς τὴν διάνοιαν ἐμπίπτουσιν οὕτως, ὥστε καὶ τὰς ἐπιστήμας ἐκβάλλειν. τοῖς δὲ τὰ σώματα εὖ ἔχουσι πολλὴ ἀσφάλεια καὶ οὐδεὶς κίνδυνος διά γε τὴν τοῦ σώματος καχεξίαν τοιοῦτόν τι παθεῖν, εἰκὸς δὲ μᾶλλον πρὸς τὰ ἐναντία τῶν διὰ τὴν καχεξίαν γιγνομένων τὴν εὐεξίαν χρήσιμον εἶναι. καίτοι τῶν γε τοῖς εἰρημένοις ἐναντίων ἕνεκα τί οὐκ ἄν τις νοῦν ἔχων ὑπομείνειεν;

Αἰσχρὸν δὲ καὶ τὸ διὰ τὴν ἀμέλειαν γηρᾶναι, πρὶν ἰδεῖν ἑαυτὸν ποῖος ἂν κάλλιστος καὶ κράτιστος τῷ σώματι γένοιτο. ταῦτα δὲ οὐκ ἔστιν ἰδεῖν ἀμελοῦντα· οὐ γὰρ ἐθέλει αὐτόματα γίγνεσθαι.

Diogenes Laertius, 1.37.2

“When someone asked who is lucky, [Thales said] “whoever has a healthy body, a sophisticated mind, and teachable nature.”

τίς εὐδαίμων, “ὁ τὸ μὲν σῶμα ὑγιής, τὴν δὲ ψυχὴν εὔπορος, τὴν δὲ φύσιν εὐπαίδευτος.”

Know-nothings, Faith-healers, and Quacks: Mystifying and Abusing Mental Illness

Hippocrates of Cos, The Sacred Disease 1 and 2

“This work is about that disease which people call “sacred”. It does not seem to me to be more divine or more sacred than any of the rest of the diseases, but it also has a natural cause and people have assumed it is sacred because of their own inexperience and their considerable wonder over how different it seems to them.”

[…]

Περὶ τῆς ίερῆς νούσου καλεομένης ὧδ᾿ ἔχει. οὐδέν τί μοι δοκεῖ τῶν ἄλλων θειοτέρη εἶναι νούσων οὐδὲ ἱερωτέρη, ἀλλὰ φύσιν μὲν ἔχει καὶ πρόφασιν, οἱ δ᾿ ἄνθρωποι ἐνόμισαν θεῖόν τι πρῆγμα εἶναι ὑπὸ ἀπειρίης καὶ θαυμασιότητος, ὅτι οὐδὲν ἔοικεν ἑτέροισι·

“Those who first claimed that the disease is divinely caused seem to me to be something like the wizards, snake-oil salesmen, faith-healers, and quacks of today, those kinds of men who pretend to great piety and superior knowledge. These kinds of healers shelter themselves and use superstition as a shield against their own helplessness when they have nothing they can do to help. They claim that this affliction is sacred so it won’t be clear that they don’t know anything. They add a ready-made story and throw in a treatment in order to keep their own position strong.”

Ἐμοὶ δὲ δοκέουσιν οἱ πρῶτοι τοῦτο τὸ νόσημα ἱερώσαντες τοιοῦτοι εἶναι ἄνθρωποι οἷοι καὶ νῦν εἰσι μάγοι τε καὶ καθάρται καὶ ἀγύρται καὶ ἀλαζόνες, οὗτοι δὲ καὶ προσποιέονται σφόδρα θεοσεβέες εἶναι καὶ πλέον τι εἰδέναι. οὗτοι τοίνυν παραμπεχόμενοι καὶ προβαλλόμενοι τὸ θεῖον τῆς ἀμηχανίης τοῦ μὴ ἔχειν ὅ τι προσενέγκαντες ὠφελήσουσι, καὶ ὡς μὴ κατάδηλοι ἔωσιν οὐδὲν ἐπιστάμενοι, ἱερὸν ἐνόμισαν τοῦτο τὸ πάθος εἶναι· καὶ λόγους ἐπιλέξαντες ἐπιτηδείους τὴν ἴησιν κατεστήσαντο ἐς τὸ ἀσφαλὲς σφίσιν αὐτοῖσι,

As Vivian Nutton makes clear in the overview of Mental Illness in the Ancient World (available in Brill’s New Pauly), Hippocrates Breaks from Ancient Near Eastern and Early Greek tradition here in offering physical explanations for mental illness of all kinds instead of divine explanations. Platonic and Aristotelian traditions follow with variations on somatism (the body as the cause), adding in addition to the humors, bile, and disharmony among the organs, habits (excessive consumption, actions) and environments. These approaches were refined by Hellenistic doctors and the work of Rufus and Galen where treatments also came to include psychotherapeutic as well as the physical treatments. The swing towards demonic possession as an explanation during Late Antiquity and the Christian middle ages took mental health approaches back towards the ‘sacred’ explanations of pre-rational antiquity.

Epictetus, Treatises Collected by Arrian, 2.15: To those who cling tenaciously to any judgments they have made 

“Whenever some people hear these words—that it is right to be consistent, that the moral person is free by nature and never compelled, while everything else may be hindered, forced, enslaved, subjected to others—they imagine that it is right that they maintain every judgment they have made without compromising at all.

But the first issue is that the judgment should be a good one. For, if I wish to maintain the state of my body, it should be when it is healthy, well-exercised. If you show me that you have the tones of a fevered mind and brag about it, I will say ‘Dude, look for a therapist. This is not health, but sickness.’ “

The Key to a Long Life: Magic (Or Maybe Climate and Diet)

Lucian, Octogenarians 3-5

“Homer claims that Nestor, obviously, the wisest of the Achaians, lived more than three generations, a man the poet explains to us was best trained in both mind and body. And the prophet Teiresis, well tragedy has him living through six generations. It might be credible that a man dedicated to the gods and who followed a reverent diet might live as long as possible.

It is recorded that whole clans of people are very long-lived thanks to their way of life—for example, the people of the Egyptians called holy-authors, the exegetes of myth in Assyria and Arabia, and the people the Indians call Brahmans, men who pursue philosophy with precision. There are also the people called the magoi, that prophetic clan dedicated to the gods among the Persians, Parthians, Bactrians, Khoasmians, Arians, Sacae, Medes, and among many other barbarian people. The magoi are strong and live many years because they learn to use magic and eat with considerable discipline.

There are, in addition, entire peoples who are long-lived: for example, some people record that the Sêres live up to 300 years. According to some authors, this is because of the weather; others claim that it is their soul or their diet that is responsible for the length of their lives—for, they claim that the whole nation drinks only water. It is reported that the people of Athos live 130 years or that the Chaldeans live over a hundred and that they rely on barley bread as a medicine to keep their vision sharp.”

Science This! Some Ancient Theories on Eclipses

N.B. This selection is by no means exhaustive.

Xenophanes, fr.  D34

“Xenophanes [says eclipses] come from flames going out and that a different one happens again in the east. He reports in addition that there was an eclipse for an entire month and also a total eclipse that made the day seem like night.”

D34 (A41) Aët. 2.24.4 (Ps.-Plut.) [περὶ ἐκλείψεως ἡλίου]

Ξενοφάνης κατὰ σβέσιν· ἕτερον δὲ πάλιν πρὸς ταῖς ἀνατολαῖς γίνεσθαι· παριστόρηκε δὲ καὶ ἔκλειψιν ἡλίου ἐφ᾽ ὅλον μῆνα καὶ πάλιν ἔκλειψιν ἐντελῆ, ὥστε τὴν ἡμέραν νύκτα φανῆναι.

Xenophanes fr. D35

“Xenophanes says that there are many suns and moons arrayed along the earth’s latitudes, segments and zones. At certain times, he says, the disk falls out of the sky to some uninhabited place of the earth and an eclipse appears because it left empty space.”

D35 =(Stob.; cf. Ps.-Plut.) [περὶ ἐκλείψεως ἡλίου]

Ξενοφάνης· πολλοὺς εἶναι ἡλίους καὶ σελήνας κατὰ τὰ κλίματα τῆς γῆς καὶ ἀποτομὰς καὶ ζώνας. κατὰ δέ τινα καιρὸν ἐκπίπτειν τὸν δίσκον εἴς τινα ἀποτομὴν τῆς γῆς οὐκ οἰκουμένην ὑφ’ ἡμῶν καὶ οὕτως ὡσπερεὶ κενεμβατοῦντα ἔκλειψιν ὑποφαίνειν [. . . = D31].

Anaximander, Fr. 26

“Anaximander says that the [moon] is a wheel nineteen times larger than the earth, like the wheel of a chariot it has a hollow rim filled with fire similar to that of the sun, situated at an angle, like that one. It has a single exhalation point like the mouth of bellows. An eclipse happens when the wheel turns.”

Aët. 2.25.1 (Stob., cf. Ps.-Plut.)

Ἀναξίμανδρος κύκλον εἶναι ἐννεακαιδεκαπλασίονα τῆς γῆς, ὅμοιον ἁρματείῳ τροχῷ κοίλην ἔχοντι τὴν ἁψῖδα καὶ πυρὸς πλήρη καθάπερ τὸν τοῦ ἡλίου, κείμενον λοξόν, ὡς κἀκεῖνον, ἔχοντα μίαν ἐκπνοὴν οἷον πρηστῆρος αὐλόν. ἐκλείπειν δὲ κατὰ τὰς ἐπιστροφὰς τοῦ τροχοῦ.

Heraclitus Fr. 20 (=Stob)

“Herakleitos and Hekateios say that the sun is a burning specter from the sea and that it is bowl-shaped and curved on one-side. They say an eclipse happens because of the turn of the bowl shape so that the hollow side turns up and the curved side turns down to our vision.”

     ῾Ηράκλειτος καὶ ῾Εκαταῖος ἄναμμα νοερὸν τὸ ἐκ θαλάττης εἶναι τὸν ἥλιον. —Σκαφοειδῆ δ’ εἶναι, ὑπόκυρτον. —Γίνεσθαι δὲ τὴν ἔκλειψιν κατὰ τὴν τοῦ σκαφοειδοῦς στροφήν, ὥστε τὸ μὲν κοῖλον ἄνω γίγνεσθαι, τὸ δὲ κυρτὸν κάτω πρὸς τὴν ἡμετέραν ὄψιν.

Empedocles, Fr. D133

“Empedocles says that an eclipse happens when the moon moves under the sun”

D133 = Aët. 2.24.7 (Stob.) [περὶ ἐκλείψεως ἡλίου]

ἔκλειψιν δὲ γίνεσθαι σελήνης αὐτὸν ὑπερχομένης.

Antiphon fr. D21 and D24

 “Antiphon says that [the sun] is made of fire that feeds on the wet mist around the earth and that its rising and setting come from it leaving air that has been consumed as it attaches to air with moisture.”

     ᾿Αντιφῶν πῦρ ἐπινεμόμενον μὲν τὸν περὶ τὴν γῆν ὑγρὸν ἀέρα, ἀνατολὰς δὲ καὶ δύσεις ποιούμενον, τῷ τὸν  μὲν ἐπικαιόμενον αἰεὶ προλείπειν, τοῦ δ’ ὑπονοτιζομένου πάλιν ἀντέχεσθαι.

 “And Antiphon says [lunar eclipses] happen because of the turn of the bowl-like celestial body and its angles.”

 Ἀντιφῶν κατὰ τὴν τοῦ σκαφοειδοῦς στροφὴν καὶ τὰς περικλίσεις

Anaxagoras, fr. D4.7

“Anaxagoras says that the moon eclipses when the earth is in the way and sometimes because of the celestial bodies below the moon; the sun eclipses because the moon gets in the way during its new phase.”

D4 (< A42) Ps.-Hippolytus, Refutation of All Heresies

ἐκλείπειν δὲ τὴν σελήνην γῆς ἀντιφραττούσης, ἐνίοτε δὲ καὶ τῶν ὑποκάτω τῆς σελήνης, τὸν δὲ ἥλιον ταῖς νουμηνίαις σελήνης ἀντιφραττούσης.

Aristotle, Posterior Analytics, II 90a (On Lunar Eclipses)

“What is an eclipse? The stealing of light from the moon by the superposition of the earth. Saying “what is an eclipse” is the same thing as saying “why does the moon eclipse”. Because the light of the sun leaves it when the earth gets in the way.”

τί ἐστιν ἔκλειψις; στέρησις φωτὸς ἀπὸ σελήνης ὑπὸ γῆς ἀντιφράξεως. διὰ τί ἔστιν ἔκλειψις, ἢ διὰ τί ἐκλείπει ἡ σελήνη; διὰ τὸ ἀπολείπειν τὸ φῶς ἀντιφραττούσης τῆς γῆς.

Seneca the Younger, Natural Questions 7

“The sun has no audience unless it starts to disappear. No one looks at the moon unless it is eclipsing. Then, cities scream together and everyone makes a ruckus because of silly superstition.”

Sol spectatorem, nisi deficit, non habet. Nemo observat lunam nisi laborantem; tunc urbes conclamant, tunc pro se quisque superstitione vana strepitat.

Hippocrates: Unmarried Women are Sad Because of Periods

Hippocrates of Cos, On Girls [Peri Parthenôn] 1

“Let’s talk first concerning the disease which is called sacred and paralyzed people and the many anxieties which frighten people seriously enough that they lose their minds and believe that they see evil spirits by night or even at times by die or sometimes on all hours. Many have hanged themselves before because of this kind of vision, more often women than men.

For a woman’s nature is more depressed and sorrowful. And young women, when they are at the age of marriage and without a husband, suffer terribly at the time of their menstruation, which they did not suffer earlier in life. For blood collects later in their uterus so that it may flow out. When, then, the mouth of the exit does not create an opening, the blood pools up more because of food and the body’s growth. When the blood has nowhere to flow, it rises up toward the heart and the diaphragm. When these organs are filled, the heart is desensitized and from this transformation it becomes numb. Madness overtakes women because of this numbness.”

Πρῶτον περὶ τῆς ἱερῆς νούσου καλεομένης, καὶ περὶ τῶν ἀποπληκτικῶν, καὶ περὶ τῶν δειμάτων, ὁκόσα φοβεῦνται ἰσχυρῶς ἄνθρωποι, ὥστε παραφρονέειν καὶ ὁρῆν δοκέειν δαίμονάς τινας ἐφ᾿ ἑωυτῶν δυσμενέας, ὁκότε μὲν νυκτός, ὁκότε δὲ ἡμέρης, ὁκότε δὲ ἀμφοτέρῃσι τῇσιν ὥρῃσιν. ἔπειτα ἀπὸ τῆς τοιαύτης ὄψιος πολλοὶ ἤδη ἀπηγχονίσθησαν, πλέονες δὲ γυναῖκες ἢ ἄνδρες· ἀθυμοτέρη γὰρ καὶ λυπηροτέρη ἡ φύσις ἡ γυναικείη. αἱ δὲ παρθένοι, ὁκόσῃσιν ὥρη γάμου, παρανδρούμεναι, τοῦτο μᾶλλον πάσχουσιν ἅμα τῇ καθόδῳ τῶν ἐπιμηνίων, πρότερον οὐ μάλα ταῦτα κακοπαθέουσαι. ὕστερον γὰρ τὸ αἷμα ξυλλείβεται ἐς τὰς μήτρας, ὡς ἀπορρευσόμενον· ὁκόταν οὖν τὸ στόμα τῆς ἐξόδου μὴ ᾖ ἀνεστομωμένον, τὸ δὲ αἷμα πλέον ἐπιρρέῃ διά τε σιτία καὶ τὴν αὔξησιν τοῦ σώματος, τηνικαῦτα οὐκ ἔχον τὸ αἷμα ἔκρουν ἀναΐσσει ὑπὸ πλήθους ἐς τὴν καρδίην καὶ ἐς τὴν διάφραξιν. ὁκόταν οὖν ταῦτα πληρωθέωσιν, ἐμωρώθη ἡ καρδίη, εἶτ᾿ ἐκ τῆς μωρώσιος νάρκη, εἶτ᾿ ἐκ τῆς νάρκης παράνοια ἔλαβεν.

Hippocrates should have consulted a woman physician like Trotula

A Healthy Mind in A Healthy Body, but Greek

Xenophon, Memorabilia 3.12

“For all of the uses of the body it makes a big difference to keep it in as good a condition as possible. Even for thinking, in which the use of the body seems least important, who does not know that many things fail in its practice because the body is not healthy? Forgetfulness, depression, ill temper and madness often strike the mind so badly because of bodily afflictions that it drives out understanding.

There is great stability for those who have strong bodies and there is, at least, no danger from suffering something like this because of physical affliction. No, it is likely that the useful help will develop as the opposite to those things that happen from affliction. And, indeed, what wouldn’t someone who has some sense try to forestall the opposite to those things I have mentioned?”

πάσαις δὲ ταῖς τοῦ σώματος χρείαις πολὺ διαφέρει ὡς βέλτιστα τὸ σῶμα ἔχειν· 6ἐπεὶ καὶ ἐν ᾧ δοκεῖς ἐλαχίστην σώματος χρείαν εἶναι, ἐν τῷ διανοεῖσθαι, τίς οὐκ οἶδεν, ὅτι καὶ ἐν τούτῳ πολλοὶ μεγάλα σφάλλονται διὰ τὸ μὴ ὑγιαίνειν τὸ σῶμα; καὶ λήθη δὲ καὶ ἀθυμία καὶ δυσκολία καὶ μανία πολλάκις πολλοῖς διὰ τὴν τοῦ σώματος καχεξίαν εἰς τὴν διάνοιαν ἐμπίπτουσιν οὕτως, ὥστε καὶ τὰς ἐπιστήμας ἐκβάλλειν. 7τοῖς δὲ τὰ σώματα εὖ ἔχουσι πολλὴ ἀσφάλεια καὶ οὐδεὶς κίνδυνος διά γε τὴν τοῦ σώματος καχεξίαν τοιοῦτόν τι παθεῖν, εἰκὸς δὲ μᾶλλον πρὸς τὰ ἐναντία τῶν διὰ τὴν καχεξίαν γιγνομένων τὴν εὐεξίαν χρήσιμον εἶναι. καίτοι τῶν γε τοῖς εἰρημένοις ἐναντίων ἕνεκα τί οὐκ ἄν τις νοῦν ἔχων ὑπομείνειεν;

 

Xenophon elaborates on some of this earlier

Xenophon, Memorabilia 3.5

“Certainly it is necessary—since the city does not provide public expenses for war—not to overlook it privately, nor otherwise to care for yourself less. Know well that you be no worse off in any other struggle or action because you have put your body in better shape. For the body is useful in everything people do. In all functions of the body it makes a big difference that the body is as healthy as possible. Even in something you might think the body is of little use—thinking—who doesn’t know that great errors come from having a sick body?

Forgetfulness, loss of spirit, ill-temper and madness often impinge upon perception because of the weakness of the body so badly that all knowledge is expelled. But for those who are healthy in body it is a great protection and they suffer no suffer no such risk of suffering this kind of thing because of the weakness of their body. It is probably that for those who have a healthy condition they will have the opposite experience. And, certainly, won’t anyone with some sense endure anything for the opposite of these things that have been mentioned?”

Anyway, is it not shameful to grow old because of carelessness before seeing how beautiful and strong a person you might be thanks to your body? It is not possible to witness this for someone who doesn’t make an effort. For it is not willing to develop on its own.”

Οὔτοι χρὴ ὅτι ἡ πόλις οὐκ ἀσκεῖ δημοσίᾳ τὰ πρὸς τὸν πόλεμον, διὰ τοῦτο καὶ ἰδίᾳ ἀμελεῖν, ἀλλὰ μηδὲν ἧττον ἐπιμελεῖσθαι. εὖ γὰρ ἴσθι, ὅτι οὐδὲ ἐν ἄλλῳ οὐδενὶ ἀγῶνι οὐδὲ ἐν πράξει οὐδεμιᾷ μεῖον ἕξεις διὰ τὸ βέλτιον τὸ σῶμα παρεσκευάσθαι· πρὸς πάντα γάρ, ὅσα πράττουσιν ἄνθρωποι, χρήσιμον τὸ σῶμά ἐστιν· ἐν πάσαις δὲ ταῖς τοῦ σώματος χρείαις πολὺ διαφέρει ὡς βέλτιστα τὸ σῶμα ἔχειν· ἐπεὶ καὶ ἐν ᾧ δοκεῖς ἐλαχίστην σώματος χρείαν εἶναι, ἐν τῷ διανοεῖσθαι, τίς οὐκ οἶδεν, ὅτι καὶ ἐν τούτῳ πολλοὶ μεγάλα σφάλλονται διὰ τὸ μὴ ὑγιαίνειν τὸ σῶμα; καὶ λήθη δὲ καὶ ἀθυμία καὶ δυσκολία καὶ μανία πολλάκις πολλοῖς διὰ τὴν τοῦ σώματος καχεξίαν εἰς τὴν διάνοιαν ἐμπίπτουσιν οὕτως, ὥστε καὶ τὰς ἐπιστήμας ἐκβάλλειν. τοῖς δὲ τὰ σώματα εὖ ἔχουσι πολλὴ ἀσφάλεια καὶ οὐδεὶς κίνδυνος διά γε τὴν τοῦ σώματος καχεξίαν τοιοῦτόν τι παθεῖν, εἰκὸς δὲ μᾶλλον πρὸς τὰ ἐναντία τῶν διὰ τὴν καχεξίαν γιγνομένων τὴν εὐεξίαν χρήσιμον εἶναι. καίτοι τῶν γε τοῖς εἰρημένοις ἐναντίων ἕνεκα τί οὐκ ἄν τις νοῦν ἔχων ὑπομείνειεν;

Αἰσχρὸν δὲ καὶ τὸ διὰ τὴν ἀμέλειαν γηρᾶναι, πρὶν ἰδεῖν ἑαυτὸν ποῖος ἂν κάλλιστος καὶ κράτιστος τῷ σώματι γένοιτο. ταῦτα δὲ οὐκ ἔστιν ἰδεῖν ἀμελοῦντα· οὐ γὰρ ἐθέλει αὐτόματα γίγνεσθαι.

Diogenes Laertius, 1.37.2

“When someone asked who is lucky, [Thales said] “whoever has a healthy body, a sophisticated mind, and teachable nature.”

τίς εὐδαίμων, “ὁ τὸ μὲν σῶμα ὑγιής, τὴν δὲ ψυχὴν εὔπορος, τὴν δὲ φύσιν εὐπαίδευτος.”

Juvenal, Satire 10.356

“We must beg for a healthy mind in a healthy body”
