There is a Byzantine didactic poem based on Greek medical treatises. Thankfully, it does not skip the good stuff.
The poem is from a collection of didactic verses attributed to Michael Psellos of Constantinople who lived and worked in the 11th century CE. The text comes from the Teubner edition of his poems edited by L. G. Westernik (1982).
Poemata 9.841
“One kind of melancholy is lykanthropy.
And it is clearly a type of misanthropy.
Mark thus a man who rushes from the day
When you see him at night running round graves,
With a pale face, dumb dry eyes, not a care in his rage.”
Μελάγχολόν τι πρᾶγμα λυκανθρωπία·
ἔστι γὰρ αὐτόχρημα μισανθρωπία,
καὶ γνωριεῖς ἄνθρωπον εἰσπεπτωκότα
ὁρῶν περιτρέχοντα νυκτὸς τοὺς τάφους,
ὠχρόν, κατηφῆ, ξηρόν, ἠμελημένον.
