Cicero, De Divinatione 2.135
“Alexander fell into a deep sleep while sitting near his friend. The story is that the snake his mother raised appeared to him while he was sleeping carrying a root in its mouth and somehow revealing the name of the place where the root grew nearby.
The snake claimed that the root had so much power that it could easily heal Ptolomaeus. Once Alexander woke up, he told his friends the dream and sent people to find the root. When it was found, it didn’t cure only Ptolomaeus, but many of the soldiers who had been wounded by the same type of arrow.”
Alexander assidens somno est consopitus. Tum secundum quietem visus ei dicitur draco is, quem mater Olympias alebat, radiculam ore ferre et simul dicere, quo illa loci nasceretur (neque is longe aberat ab eo loco), eius autem esse vim tantam, ut Ptolomaeum facile sanaret. Cum Alexander experrectus narrasset amicis somnium, emissi sunt, qui illam radiculam quaererent; qua inventa et Ptolomaeus sanatus dicitur et multi milites, qui erant eodem genere teli vulnerati.
Aristotle, On Marvellous things heard, 86 [=837a]
“People claim that among the Celts there is a drug which they call the “arrow” [toxikon]. They report that it induces so quick a death that the Celts’ hunters, whenever they have shot a deer or some other animal, rush ahead to cut off its flesh before it is penetrated completely by the drug both for the sake of using the meat and so that the animal might not rot.
They also claim that the oak tree’s bark has been found to be an antidote for the poison. But others claim that there is a leaf which that call “raven’s leaf” because they have seen ravens, once they taste the poison mentioned before and start to feel the drug’s effect, rush to this leaf and stop their suffering by eating it.”
Φασὶ δὲ παρὰ τοῖς Κελτοῖς φάρμακον ὑπάρχειν τὸ καλούμενον ὑπ᾿ αὐτῶν τοξικόν· ὃ λέγουσιν οὕτω ταχεῖαν ποιεῖν τὴν φθορὰν ὥστε τῶν Κελτῶν τοὺς κυνηγοῦντας, ὅταν ἔλαφον ἢ ἄλλο τι ζῷον τοξεύσωσιν, ἐπιτρέχοντας ἐκ σπουδῆς ἐκτέμνειν τῆς σαρκὸς τὸ τετρωμένον πρὸ τοῦ τὸ φάρμακον διαδῦναι, ἅμα μὲν τῆς προσφορᾶς ἕνεκα, ἅμα δὲ ὅπως μὴ σαπῇ τὸ ζῷον. εὑρῆσθαι δὲ τούτῳ λέγουσιν ἀντιφάρμακον τὸν τῆς δρυὸς φλοιόν· οἱ δ᾿ ἕτερόν τι φύλλον, ὃ καλοῦσι κοράκιον διὰ τὸ κατανοηθῆναι ὑπ᾿ αὐτῶν κόρακα, γευσάμενον τοῦ φαρμάκου καὶ κακῶς διατιθέμενον, ἐπὶ τὸ φύλλον ὁρμήσαντα τοῦτο καὶ καταπιόντα παύσασθαι τῆς ἀλγηδόνος.
This comes from the Greek nominal root for bow:
Greek Anthology 5.225
“I have a wound from love: from it pours not blood
But tears and a scar will never close it.
I am undone by this evil and not even Makhaon
Could heal me by applying his gentle drugs.
I am Telephos, girl—be my faithful Achilles:
Stop this longing you caused with your beauty.”
῞Ελκος ἔχω τὸν ἔρωτα· ῥέει δέ μοι ἕλκεος ἰχὼρ
δάκρυον, ὠτειλῆς οὔποτε τερσομένης.
εἰμὶ καὶ ἐκ κακότητος ἀμήχανος, οὐδὲ Μαχάων
ἤπιά μοι πάσσει φάρμακα δευομένῳ.
Τήλεφός εἰμι, κόρη, σὺ δὲ γίνεο πιστὸς ᾿Αχιλλεύς·
κάλλεϊ σῷ παῦσον τὸν πόθον, ὡς ἔβαλες.
A few notes to make this make sense: In the Iliad Makhaon is a healer who ministers to the wounded captains. In myth, Telephos, a son of Herakles, is wounded by Achilles’ spear and can only be healed by the man who hurt him. Achilles encounters Telephos at the beginning of the war when the Greeks mistakenly attack Mysia (believing it to be Troy!). He is later healed in exchange for leading the Greeks to Troy.
So, this odd epigram becomes a tad bit odder thanks to knowing the references. It is ascribed to a poet named Macedonius and is in book 5 of The Greek Anthology (the Erotic Epigrams).
