Saint Helen, often referred to as Saint Helena of the Cross, was the mother of the great emperor Constantine. When Constantine became the sole ruler of the Roman Empire, Helena was granted man honors. She was named Augusta, or empress, in 325, and enjoyed great influence in the imperial court.
She converted to Christianity and built many churches in Rome and the Holy Land. On pilgrimage to the Holy Land she found the True Cross, and even recorded by Rufinus Sulpicius Severus and St. Ambrose. She was also known to generously help the poor. Because of her piety, she exerted a great influence over Constantine and he held her in high esteem.
St. Helen is often depicted in art as an empress, holding a cross. Her feast day is August 18th.
