Macarius Chrysocephalus (14th cent.: “He was called Chrysocephalus because, having made numerous extracts from the works of the fathers, he arranged them under different heads, which he called χρυσᾶ κεφάλαια, or ‘Golden Heads.’ — William Smith, A Dictionary of Greek and Roman biography and mythology), Proverbs 2.92.1:
<Γαλλιστὶ τεμεῖν:> ἐπὶ τῶν ἀφροντίστως ἀπαλλαγὴν πραγμάτων ποιήσασθαι βουλομένων. Γάλλοι γὰρ καλοῦνται οἱ ἀποτετμημένοι → “To cut in the Gallos fashion” [A Gallos was a priest of Cybele who ritually “cut” (castrated) himself]: said of those who heedlessly seek to cut things short. The Galloi, you see, are called “the cutoffs.”
LSJ, with their resort to the British saying “Cut the Gordian knot,” i.e. “solve a difficult problem,” seem to have missed the point here.
