St. Aloysius was born in Castiglione, Italy. The first words St. Aloysius spoke were the Holy Names of Jesus and Mary. He was destined for the military by his father but by the age of 9 Aloysius had decided on a religious life, and made a vow of perpetual virginity. To safeguard himself from possible temptation, he would keep his eyes persistently downcast in the presence of women.  When he was 18, he joined the Jesuits, after finally breaking down his father, who had refused his entrance into the order. He served in a hospital during the plague of 1587 in Milan, and died from it at the age of 23. The last word he spoke was the Holy Name of Jesus.

He is depicted with his eyes focused on the cross, and holding lilies as a symbol of his virginity.

O Saint Aloysius, adorned with angelical manners, although I am thy unworthy servant, I recommend to thee in an especial manner the chastity of my soul and body; I conjure thee, by thy angelical purity, to commend me to Jesus Christ, the spotless Lamb, and to His most holy Mother, the Virgin of virgins. Preserve me from every grievous sin; never suffer me to sully my soul with any impurity; whenever thou seest me in temptation or danger of sin, ward off from me every impure thought and affection, and awakening in me the remembrance of eternity and of Jesus crucified, imprint deeply in my heart the sentiment of the fear of God. Inflame me with divine love, in order that by imitating thee on earth, I may merit to enjoy God with thee in heaven. Amen.
