From a portable codex most probably produced for use by a religious devotee from Koblenz or its vicinity. The presence of SS. Aldegund and Amand point to eastern France or the adjacent Low Countries and western Germany, but the presence of the rare local saint, Castor of Karden, on 13 February (in contemporary addition as ""Castoris +"") allows us to locate this leaf more precisely. Castor was a follower of St. Maximinus of Trier in the fourth century, who was ordained priest and settled at Karden on the Moselle in central western Germany as a hermit. In the ninth century his bones were transferred to a church dedicated to him in Koblenz, which became the main site of his worship
