Gemolus was buried at Ganna, where an abbey dedicated to him arose in 1095, built by Atto (Attone), Ardericus (Arderico), Inghizo (Inghizone) with the permission of Arnulf III, Archbishop of Milan.

[3] Himerius, who escaped, eventually succumbed to his wounds at Varese, where he was buried in the church of San Michele at Bosto.

[4] Gemolus survived the decapitation and, in the tradition of the cephalophores, collected his own head, climbed on horseback, and reunited with his uncle the bishop on a small mountain before he finally died.

Rocks stained red with a particular algae found near the Abbey of Ganna were identified with the drops of Gemolus' blood in popular tradition.

This led the monks to construct a second oratory some distance from the road in the 14th century to accommodate veneration of this particular natural phenomenon.
