History & Origin

St. Ansano was born around 284 AD into a noble Roman family. According to tradition, he was secretly baptized as an infant by his Christian nurse, Maxima. As a young man, Ansano began preaching Christianity in Rome, which led to his arrest during the Diocletian persecution. After being tortured in Rome, he was sent to Siena, where he continued his missionary work with great success, converting many citizens to Christianity. His evangelization earned him the title Apostle of Siena. Around 304 AD, during the height of the persecution, Ansano was arrested again. He was subjected to various tortures, including being thrown into boiling oil, from which he emerged unharmed. Finally, he was beheaded near Siena. His martyrdom cemented his status as Siena's primary saint and protector.
