Their unreliable Acts state that Firmus and Rusticus, kinsmen, were prominent citizens of Bergamo.

They were martyred at Verona under the Emperor Maximian after refusing to sacrifice to pagan idols.

It has been postulated that Firmus and Rusticus were actually two martyrs of Africa whose relics were translated to Verona.

[4] In 765, the relics of the martyrs were brought to Verona from Trieste by the sister of Bishop Anno.

[5] A tenth century account says that the relics of Firmus and Rusticus had first been taken to Africa, then to Capodistria and finally to Trieste, before bishop Anno had them re-buried them in a lead coffer within the high altar.
