Holy Martyrs Florus and Laurus of Illyria
The Holy Martyrs Florus and Laurus were brothers, twins both in flesh and in spirit. They lived in the second century at Byzantium and afterwards settled in Illyria, where they earned their living as stone-masons. Their teachers in this craft, Proclus and Maximus, were Christians who instructed them not only in the working of stone but also in the saving faith and the way of life pleasing to God.
The prefect of Illyria, Likaion, sent the brothers to a neighbouring district to work upon the construction of a pagan temple. The saints toiled diligently at the structure, but they distributed to the poor the wages they earned, kept strict fasts, and prayed without ceasing. Once, while they were at work, a chip of stone struck the eye of the son of the local pagan priest Mamertin, severely injuring him. The angry father came against the saints, but Florus and Laurus assured him that his son would be healed. They brought the youth to consciousness, taught him the faith, and placing their hands upon him called upon the name of Christ. The youth was instantly healed, and both he and his father were converted to Christ and baptised.
When the temple was finished the saints called the local Christians together, set up in it a cross of the Lord, and on the very night of its completion rendered the building to God by celebrating an all-night vigil within it. Hearing of this, the prefect Likaion was filled with wrath. He had the priest Mamertin and his son cast into a furnace where they perished, while three hundred of the converts were burned alive. Saints Florus and Laurus were sent under guard back to the prefect Likaion, who threw them down an empty well and ordered it covered with earth, and there they yielded their souls to God.
After many years their relics were uncovered incorrupt and were translated to Constantinople. From ancient times in the Slavonic lands the holy martyrs Florus and Laurus have been venerated as protectors of horses and herdsmen, and their icons depict them surrounded by horses entrusted to their care.
