The Bible tells Daniel's story in the Book of Daniel. Perhaps the best known episode is that of his surviving a night in a den of lions. Thus a lion is his attribute, as at right. The Vulgate Daniel (14:27-38) has a second story of Daniel in the lions' den. This time he is in for six days, and an angel arranges for a pot of stew to be brought to him from Judea by the prophet Habakkuk
Part of Daniel's story takes place in Babylon, which according to Duchet-Suchaux (113) accounts for the Phrygian cap that one sees on his portraits sometimes (example).
Daniel's sojourn in the lions' den is a particularly popular subject in the sarcophagi of the 4th century. The images of the episode always have him standing nude in orant position with two lions. Jensen ("Nudity," 313-17) relates his nudity to the Roman practice of sending victims into the arena undressed as a way of humiliating them. Usually the lions sit on either side of Daniel and face him (example), but one sarcophagus has them seated more naturalistically.
In these images we often see Habakkuk bringing bread or stew to Daniel (example). In the Vulgate passage an angel has carried Habakkuk and the food to Babylon; some sarcophagi include a second figure who could be an angel, though he has no wings or other indications of such status (example). In one unusual example it is a child who brings the bread to Daniel while two other men stand by approvingly. In another, the prophet is flanked by two men of identical appearance and it is difficult to tell who they are.
A manuscript in the collection of Basel University has a number of illustrations of the Book of Daniel, including the prophet's avoidance of the King's food, his interpretation of Nebuchadnezzar's dream, and Balthazar's feast. In all these images, and in the Bernini at right, Daniel is a beardless youth. But in what appears to be a figure of Daniel in one Croatian fresco he has a forked red beard. That fresco has him holding a banderole with a phrase that has now faded away. The beard and banderole reference Daniel's role as a prophet, as we see in Fra Angelico's Crucifixion, which includes a portrait of Daniel holding a banderole with what medievals took to be a prophecy of the Crucifixion.
As for clothing, paleo-Christian images of Daniel in the lions' den regularly picture him naked. Medieval images in the West dress him in whatever the artists think was appropriate for the courtier of an eastern potentate. Orthodox icons have him in military boots and what Tradigo calls "a short robe, a broad cloak, and a Phrygian hat."1 The latter differs somewhat from the Phrygian caps in early images of the Magi, being topped by a rounded or cube-shaped cloth construction.
