From Aelian’s Historical Miscellany 13.22 (or however you want to render Ποικίλη Ἱστορία).
Ptolemy Philopator, building a temple to Homer, erected a beautiful statue of him and in a circle around it placed all the cities who claim Homer as their own.
The painter Galaton depicted Homer vomiting and the other poets gathering up his vomit.
Πτολεμαῖος ὁ Φιλοπάτωρ κατασκευάσας Ὁμήρῳ νεών, αὐτὸν μὲν καλῶς ἐκάθισε, κύκλῳ δὲ τὰς πόλεις περιέστησε τοῦ ἀγάλματος, ὅσαι ἀντιποιοῦνται τοῦ Ὁμήρου.
Γαλάτων δὲ ὁ ζωγράφος ἔγραψε τὸν μὲν Ὅμηρον αὐτὸν ἐμοῦντα, τοὺς δὲ ἄλλους ποιητὰς τὰ ἐμημεσμένα ἀρυομένους.
This Ptolemy, Ptolemy IV, ruled Egypt in the final two decades of the third century BC. Galaton is otherwise unknown.
