St. Nazarius was baptized by Pope Linus at Rome; in his turn he baptized the youthful Celsus. They were both beheaded at Milan about the year 368. Their bodies, buried in a garden outside the city, were found by St. Ambrose in 395. The body of St. Nazarius appeared as if it had just been beheaded. It was placed by St. Ambrose in the Basilica Romana. The body of the boy Celsus was found in another part of the garden, but was not removed. However, a basilica was later built in his honor.
