Historical detail regarding these martyrs is sparse; their memory is preserved because the three were mentioned in a sermon by Maximus of Turin.

While the legion's leader, Saint Maurice, was killed at Agaunum, along with many other soldiers, Solutor, Adventor, and Octavius managed to escape.

[1] According to legend, a vision of the Virgin Mary appeared in a dream to John Bosco in 1844 or 1845 and revealed the site of the martyrdom of Adventor and Octavius.

[1][2] The cult of Saint Solutor is particularly strong in the diocese of Ivrea, and he is also venerated in Caravino, Romano Canavese, and Strambino.

The codex called the Codice della Catena depicts Saints Octavius, Maximus of Turin, Adventor, Solutor, John the Baptist, and Secundus of Asti.
