Saint Euphrasia (380 – March 13, 410 AD) was the only daughter of Antigonus, a nobleman of the court of Emperor Theodosius I, to whom he was related, and of Euphrasia, his wife, a noble and virtuous lady. After her birth, St. Euphrasia's parents bound themselves by a vow to live together in perpetual continence. When Antigonus died his widow and young daughter withdrew together to Egypt, near a monastery of nuns who led a very austere life. This was less than a century since St. Anthony had established his first monastery; but monasticism in that time had spread with incredible speed.
