as early as the 7th century, certainly by the early 10th century (the oldest certain depiction of Theodore killing a dragon is at Aghtamar, dated c. 920). Theodore is reported as having destroyed a dragon near Euchaita in a legend not younger than the late 9th century. The earliest image of St Theodore as a horseman (named in Latin) is from Vinica, North Macedonia and, if genuine, dates to the 6th or 7th century. Here, Theodore is not slaying a dragon, but holding a draco standard. The "Christianisation" of the Thracian horseman iconography can be traced to the Cappadocian cave churches of Göreme, where frescoes of the 10th century show military saints on horseback confronting serpents with one, two or three heads. One of the earliest examples is from the church known as Mavrucan 3 (), generally dated to the 10th century, which portrays two "sacred riders" confronting a two serpents twined around a tree, in a striking parallel to the Dioskuroi stela, except that the riders are now attacking the snake in the "tree of life" instead of a boar. In this example, at least, there appear to be two snakes with separate heads, but other examples of 10th-century Cappadocia show polycephalous snakes. A poorly preserved wall-painting at the ("Snake Church") that depicts the two saints Theodore and George attacking a dragon has been tentatively dated to the 10th century, or alternatively even to the mid-9th. A similar example, but showing three equestrian saints, Demetrius, Theodore and George, is from the "Zoodochos Pigi" chapel in central Macedonia in Greece, in the prefecture of Kilkis, near the modern village of Kolchida, dated to the 9th or 10th century. A 12th-century depiction of Theodore as equestrian dragon-slayer is found in four muqarna panels in the nave of the Cappella Palatina in Palermo. The dragon motif was transferred to the George legend from that of his fellow soldier saint, Saint Theodore Tiro. The transfer of the dragon iconography from Theodore, or Theodore and George as "Dioskuroi" to George on his own, first becomes tangible in the early 11th century. The oldest certain images of St. George combatting the serpent date are still found in Cappadocia, in particular the image in the church of Saint Barbara, Soganh (dated 1006 or 1021). The two St Theodores Numerous conflicting legends grew up about the life and martyrdom of St Theodore so that, in order to
