In one of his thirty topics for “Table-Talk”, Plutarch suggests the effects of love on a poet as a starting point…Of course, if you want debates about Love, the Symposia of Plato and Xenophon are good inspirations too…
Plutarch: “Table-Talk” Moralia 622 Why Do We Say that Eros Teaches a Poet?
“The question “how it can be said truthful that “Love teaches the poet” even though he was songless before, was considered at Sossius’ house after some Sapphic verses were performed. Philoxenos claims that the Kyklops “cured love with well-voiced songs.”
Love is said to be clever at every kind of audacity and at furnishing ingenuity, just as Plato calls love “speedy” and “prepared for everything”. Indeed, love makes a quiet man talkative and the withdrawn man solicitous; it makes the carefree and easygoing person serious and sedulous. And what is especially wondrous, a cheap and miserly man, after he falls in love, becomes soft, compliant, and persuadable just as iron in fire. Thus what seems like a joke is not completely absurd in the proverb “a lover’s purse is locked by an onion leaf”.
It has also been said that being in love is like being drunk. For it makes people hot, happy, and troubled–after they come into this state, they fall into speech that sounds like songs or verse. People claim Aeschylus wrote his tragedies while drinking, even completely drunk. My grandfather Lamprias was himself most innovative and insightful when he was drinking. He was in the habit of saying that just as with incense, he too was activated by warmth.
In addition, people see the ones they want most sweetly—and are no less moved to praise them than to see them. In praise, love, voluble in everything, is the most effusive. When people are in love they want to persuade everyone how beautiful and good are the ones they love, because they believe it themselves.”
Πῶς εἴρηται τὸ “ποιητὴν δ᾿ ἄρα Ἔρως διδάσκει”
Πῶς εἴρηται τὸ ποιητὴν δ᾿ ἄραἜρως διδάσκει, κἂν ἄμουσος ᾖ τὸ πρίν ἐζητεῖτο παρὰ Σοσσίῳ Σαπφικῶν τινων ᾀσθέντων, ὅπου καὶ τὸν Κύκλωπα “μούσαις εὐφώνοις ἰᾶσθαι” φησὶ “τὸν ἔρωτα” Φιλόξενος. ἐλέχθη μὲν οὖν ὅτι πρὸς πάντα τόλμαν ὁ ἔρως καὶ καινοτομίαν συγχορηγῆσαι δεινός ἐστιν, ὥσπερ καὶ Πλάτων “ἴτην” αὐτὸν καὶ “παντὸς ἐπιχειρητὴν” ὠνόμασεν· καὶ γὰρ λάλον ποιεῖ τὸν σιωπηλὸν καὶ θεραπευτικὸν τὸν αἰσχυντηλόν, ἐπιμελῆ δὲ καὶ φιλόπονον τὸν ἀμελῆ καὶ ῥᾴθυμον· ὃ δ᾿ ἄν τις μάλιστα θαυμάσειεν, φειδωλὸς ἀνήρ τε καὶ μικρολόγος ἐμπεσὼν εἰς ἔρωτα καθάπερ εἰς πῦρ σίδηρος ἀνεθεὶς καὶ μαλαχθεὶς ἁπαλὸς καὶ ὑγρὸς καὶ ἡδίων, ὥστε τουτὶ τὸ παιζόμενον μὴ πάνυ φαίνεσθαι γελοῖον ὅτι “πράσου φύλλῳ τὸ τῶν ἐρώντων δέδεται βαλλάντιον.”
Ἐλέχθη δὲ καὶ ὅτι τῷ μεθύειν τὸ ἐρᾶν ὅμοιόν ἐστιν· ποιεῖ γὰρ θερμοὺς καὶ ἱλαροὺς καὶ διακεχυμένους, γενόμενοι δὲ τοιοῦτοι πρὸς τὰς ἐπῳδοὺς καὶ ἐμμέτρους μάλιστα φωνὰς ἐκφέρονται· καὶ τὸν Αἰσχύλον φασὶ τὰς τραγῳδίας πίνοντα ποιεῖν καὶ διαθερμαινόμενον. ἦν δὲ Λαμπρίας ὁ ἡμέτερος πάππος ἐν τῷ πίνειν εὑρετικώτατος αὐτὸς αὑτοῦ καὶ λογιώτατος· εἰώθει δὲ λέγειν ὅτι τῷ λιβανωτῷ παραπλησίως ὑπὸ θερμότητος ἀναθυμιᾶται. καὶ μὴν ἥδιστα τοὺς ἐρωμένους ὁρῶντες οὐχ ἧττον ἡδέως ἐγκωμιάζουσιν ἢ ὁρῶσιν, καὶ πρὸς πάντα λάλος ὢν ἔρως λαλίστατός ἐστιν ἐν τοῖς ἐπαίνοις. αὐτοί τε γὰρ οὕτως πεπεισμένοι τυγχάνουσιν καὶ βούλονται πεπεῖσθαι πάντας ὡς καλῶν καὶ ἀγαθῶν ἐρῶντες.
