Eugendus (also Augendus; French: Oyand, Oyan; c. 449 – January 1, 510) was the fourth abbot of Condat Abbey, at Saint-Claude, Jura.
He was instructed in reading and writing by his father, who had become a priest, and at the age of seven was entrusted to Romanus and Lupicinus to be educated at Condat Abbey.
[3] After the monastery, which Romanus had built of wood, was destroyed by fire, Eugendus erected another of stone, and improved the community life; thus far the brethren had lived in separate cells after the fashion of the Eastern ascetics.
When Eugendus felt his end approaching he had his breast anointed by a priest according to the custom, took leave of his brethren, and died quietly after five days,[2] at the age of sixty-one.
A few years after his death, his successor, Viventiolus, erected a shrine over his tomb in the abbey church, to which numerous pilgrims travelled.
