Saint Cassian of Tangier was a Christian saint of the 3rd century. He is traditionally said to have been beheaded on 3 December, AD 298, during the reign of Diocletian. The Passion of Saint Cassian is appended to that of Saint Marcellus of Tangier. It is, however, not considered reliable.[1] Saint Cassian of Tangier is mentioned by Prudentius (born 348) in his hymn Liber Peristephanon (De Coronis Martyrum) (Carmen IV, 45-48 [1]): "Ingeret Tingis sua Cassianum, festa Massylum monumenta regum, qui cinis gentes domitas coegit. ad iuga Christi."
