VIDOVDAN MARTYR: "If I choose a kingdom, choose the Kingdom on Earth, that kingdom is but paltry and small; yet the Kingdom of Heaven is forever and knows no bounds." Lazar's fateful choice, the Vow of Kosovo, the sacrifice that enables Resurrection. His canonization shortly after the battle - and the vibrant folklore that was quickly to follow - made its date, June 15 (currently June 28 by Gregorian calendar) primarily honor the Holy Martyr Lazar, and by association martyrs from later wars. Though known traditionally as "Vidovdan" (implying also a connection to St. Vitus), the Orthodox Church additionally honors on that day only prophet Amos of the Old Testament. Epic tradition, in the memorable account of the building of the Ravanica Church, holds that he was the family patron and feast (slava) of Prince Lazar himself. A rare silver dinar shows Lazar with a saintly nimbus around his head, suggesting a posthumous issue shortly after his martyrdom. The 1741 lithography of Lazar Kefalophoros, made by Hristofor Zefarovic in Vienna, displays the prevailing Baroque iconography.
