Leontius of Fréjus

Starting from an early date, he, alongside the Blessed Virgin, was considered patron of the cathedral church of Fréjus.

[2] The principal occurrence during the episcopate of Leontius of Fréjus was the establishment of Lérins Abbey at the beginning of the fifth century.

Honoratus called him his superior and his father, whilst John Cassian who governed the numerous religious of the Abbey of St. Victor, Marseille, dedicated most of his "Conferences" to him.

They were confirmed by the Third Council of Arles, and seem to have been the beginning of those immunities which from then on were enjoyed in an increasing degree by the religious communities.

Another tradition, making Leontius a martyr, does not seem older than the beginning of the thirteenth century, and merits no credence.
