This passage has recently (1891) acquired a special interest from the controversy concerning Mr. Calderon’s picture, representing St. Elisabeth of Hungary as kneeling naked before the altar.  The word “naked” (γυμνός, nudus) is not in itself decisive, but here in St. Cyril’s account of Baptism absolute nakedness seems to be implied; for though women sometimes wore an under-tunic (χιτώνιον), men had nothing beneath the tunic proper (χιτών), which is here said to be put off.  According to Theophylact, on Matt. v. 40, the chiton was properly τὸ παρ᾽ ἡμῖν λεγόμενον ὑποκάμισοε.  See Dictionary of Biblical Antiquities, “Baptism,” § 48.
