[1] Veneration of Tegulus actually arose at the end of the 10th century, when during the episcopate of Warmondus (Varmondo), the Tegulus's relics were discovered in a sepulcher situated a short distance away from Ivrea.
[1] The relics were translated to the cathedral of Ivrea within the city walls, and placed in the chapel of San Giacomo.
[1] According to local tradition, Tegulus survived the decimation of his legion but was eventually beheaded on the road to Montaldo Dora, at the spot later occupied by the chapel of Santa Croce, which was built in the 14th century.
[2] Damiano Pomi theorizes that the relics may have been the remains of a soldier that were mistaken for those of a Christian martyr.
[1] The name Tegulus, as Pomi also theorizes, may in fact not have been his name at all, but a reference to the building material commonly used for Roman graves: the tegula or tile.
