CIMRM Supplement - 'Mithraic' altar with Apis. Stone-in-Oxney, Britain
The village church of St Mary the Virgin, in the Kent village of Stone-in-Oxney, possesses a Roman altar with the image of a bull on the front. Often supposed to be a Mithraic relief, it is in fact Apis, and so associated with the Graeco-Roman cults of Isis or Serapis.
