Illidius is credited with having cured the daughter of the Roman Emperor Magnus Maximus at Trier,[http://csla.history.ox.ac.uk/record.php?recid=E00024 Gregory of Tours. "Life of Illidius of Clermont"] and died on the return journey.[https://nominis.cef.fr/contenus/saint/1711/Saint-Allyre.html "Saint Allyre", Nominis]

His tomb attracted many pilgrims.

The fountain of St. Allyre at Clermont is known for its petrifying water, caused by calcareous deposits.
