I know the Mithras site (since my childhood) at Carrawburgh and have worked at the APX Xanten (Germany) knowing about the Mitras Altar find down the road in Kalkar.
Batava Auxiliary Units where stationed at Xanten and Kalkar until they where transfered in disgrace (after the Batava uprising 69/70AD) to the Vindolanda area.
I was just checking the connection and if the same Batavian Cohort had maybe built and used the two temples and had maybe brought the cult to the area of north England
I have been pleasantly surprised to read this inscription proving a Betavian connection to
Mitras at Carrawburgh.
The Altar found at Kalkar (not in situ.) is unfortunately dated after the official exodus of the Batavians although the Temple itself has not been found or excavated and the founding of the temple could possibly of an earlier date!

Thinking of forming a weekly group for those in the Anglosphere(USA, Canada, UK, Australia and NZ) to have a webcam call, discuss all things related to Mithras and form friends sharing a niche interest:)
