Nicasius of Rouen

While the Liber Eburneus of the cathedral of Rouen indicates St. Mellon as first Bishop of Rouen, the Liber Niger of St. Ouen and the episcopal lists dating from the twelfth century mention the episcopate of a certain Nicasius (Nicaise) as antedating that of St.

Confusion of this Denis with Dionysius the Areopagite led some to suppose that Nicasius was born in Athens.

He performed several miracles and evangelized numerous places along the Seine (among them Conflans, Andrésy, Triel, Vaux, Meulan, Mantes and La Roche-Guyon).

[2] Nicasius and his two companions were beheaded on the banks of the Epte in Gasny[3] before reaching Rouen.

Nicasius is a saint, listed in the Roman Martyrology on 11 October, his feast day.
