Although the Bible does not mention the word or idea of a halo, Christian art puts it on the heads of religious figures as a standard indication of divinity. It is a much earlier image, however, appearing with Buddha, with Krishna, and the Egyptian sun-god, Ra.
The image of the Good Shepherd seems to come from the Bible, and was painted on Christian and Jewish tombs in the Roman catacombs, but it was previously used for pagan tombs as well. Jesus may be depicted as an adult with a beard, but the earliest Good Shepherd motif is of a beardless youth wearing Roman clothing from before the Common Era.
Other images in Jewish and Christian art that are predated by pagan use are found in the catacombs: woman praying with upright hands (so-called Orant figures), Winged Victories and cupids are seen throughout the catacombs, figures eating grapes, seven steps leading to a tomb, pairs of peacocks, scrolls—are all parts of pagan art that were adapted to Christian symbolism.
C.S.Lewis, after converting to Roman Catholicism, was happy to explain these borrowings as important parallels:
preparatio evangelica, a divine hinting in poetic and ritual form at the same central truth which was later focused on and (so to speak) historicized in the Incarnation... [from the essay "Myth Became Fact and Religion without Dogma"]
Of course the more deliberate adaptation of pagan-to-Christian culture is when Pope Gregory sent Augustine to convert Britain, telling him to appropriate their holy places and customs, or when St. Boniface cut down a sacred oak and used the timber to build a church. Gregory's re-defining certain words tells a similar story.
The Christianization of Europe kept advancing, but like the Renaissance it did not happen all at once. There was a country on the Baltic Sea that is considered the last country to become officially Christian. Curiously, its capital city of Vilnius had such a large and thriving Jewish population that it was called Yerushalayim D'Lita (the "Jerusalem of Lithuania"). Tomorrow we talk about (not for the first time) Lithuania.
