They were attached to the Muscovite missionaries dispatched to the court of Algirdas, pagan Grand Duke of Lithuania. Algirdas was married to an Orthodox Christian princess, Maria of Vitebsk, and the Orthodox were permitted only to minister to the religious needs of the princess. All outside proselytizing was forbidden.

The three youths were arrested for preaching in public, and were ordered by Algirdas to consume meat in his presence during an Orthodox fasting period. When they refused, they were tortured and executed. Their bodies were kept in a glass reliquary in a crypt chapel beneath the altar of the cathedral church in the Monastery of the Holy Spirit in Vilnius, Lithuania, but has since been moved to the main sanctuary of the church. Their relics are said to be incorruptible. They were added to the Roman Calendar by Pope Paul VI in 1969.[1]
