Early, perhaps as early as the fifth century, Florus of Lodève, credited in medieval tradition with being the first bishop of Lodève and belonging to the apostolic era, arrived to Christianize the valley, and gave his name to the area, striking a rock with his staff, it was said, to create a holy spring that continued to be venerated under its Christianized guise, into the 20th century. The present town called Indiciac took shape only around the millennium, clustered around the monastery founded on the high rock in 996, at first little more than an oratory. The site, already occupied by a small monastic community, was donated to Odilo of Cluny by the Auvergnat seigneur, Astorg de Brezons; the donation was confirmed by Pope Gregory V, i.e. in 996-99, but Astorg's nephew, Amblard "le mal Hiverné" ("the furious"), the comptour perhaps asserting residual family interests in the place, seized it and laid it waste, sparing the church. Astorg and Amblard together then donated it to St Peter's, but Amblard reconsidered and erected a fortress in the ruins of the monastery, but, seized with remorse, donated it once more to Odilo of Cluny. Urban II, following the Council of Clermont (1095) consecrated the new abbey church, which received a triple dedication reflecting local tradition and present affiliations: Saint-Sauveur, Saint Pierre and Saint Flour. The diocese of Saint-Flour was established in August 1317 by the Avignon pope, John XXII;
