[1][2] Dalmatius was born in the late 400s in Gaul; he became bishop of Rodez in 524 at a relatively young man age.
In 535, Dalmatius attended the Council of Arvernum,[3] which among its sixteen decrees, held that the granting of episcopal dignity must be according to the merits and not as a result of intrigues.
In 541, he attended the Fourth Council of Orléans and on his return made a pilgrimage to the tomb of Martin of Tours.
[4] Gregory of Tours reports that Dalmatius built a church, but tore it down so often for improvements, that it was left unfinished at his death.
Dalmatius' testament requested from Childebert II that the bishop's successor not be a stranger to the see, or covetous, or married.
