Since the 12th century, his presumed bones have been kept in a shrine, which is embedded in the high altar of the Xanten Cathedral.

Tradition states that Viktor, as a Praefectus cohortis of a Cohort of the Theban Legion, was not caught up in the decimation at Agaunum but then fell victim to the persecution under Emperor Maximian together with other companions in Xanten.

[2] He was executed in the amphitheater of Castra Vetera (the site of present-day Xanten) for refusing to sacrifice to the Roman gods.

Victor was first mentioned by Gregory of Tours in connection with the discovery of the bones of a Mallosus in the village of Birten, today a suburb of Xanten.

[2] According to legend, Helena of Constantinople recovered the bones of Victor and his legion and erected a chapel in their honour.
