The presence of Christians among the barbarians has been well documented. Theophylact Simocatta wrote of a Gepid who had once long before been of the Christian religion. The author of the Strategikon documented Romans among the Sclavenes, and some of those Romans may have been Christians as well. The presence and proselytism of these Christians does not go so far as to explain how artifacts with Christian symbolism appeared on sites to the south and east of the Carpathians in the 560s. Such artifacts have been found at Botoșana and Dulceanca. Casting molds for pectoral crosses were found in the space around Eastern and Southern Carpathian mountains, starting with the 6th century.
