The Cappadocians were of notoriously bad character, and shared with the Cretans and Cilicians the discredit of illustrating τρία κάππα κάκιστα.  cf. note on Theodoret, Ecc. Hist. II. xi. p. 75.  It was Phrygians, however, who were specially notorious for cowardice.  cf. the proverb:  “More cowardly than a Phrygian hare.”  cf. Lightfoot, Coloss., etc., p 378 n.  But Cappadocia may claim the counter credit of having given birth to three of the most famous divines, Basil and the two Gregorys.
