Saints Florus and Laurus are venerated as Christian martyrs of the 2nd century. According to a Greek tale, they were twin brothers who worked as stonemasons. They were originally from Constantinople, Byzantium but settled in Ulpiana, Dardania, south of Pristina, Kosovo in the district of Illyricum. Sts. Florus and Laurus have been considered the patrons of horses in Rus and Ukraine. They have been shown on icons with horses around them. Florivsky Monastery in Kyiv and many Orthodox churches have been dedicated to the martyr twins. Peasants didn't plow with horses on their feast day for fear of causing a cattle plague. "On this day the Russians lead their horses round the church of their village."
