Extra points if Snape gets it in the nape of the neck.
BTW Severus of Antioch:
was by birth and education a pagan, who was baptized in the martyry of Leontius at Tripolis.
He almost at once openly united himself with the Acephali, repudiating his own baptism and his baptizer, and even the Catholic church itself...
Severus is said to have stirred up a fierce religious war among the population of Alexandria, resulting in bloodshed and conflagrations. To escape punishment for this violence, he fled to Constantinople...
Severus was eagerly dispatched by Anastasius to occupy the vacant patriarch of Antioch, and the very day of his enthronement solemnly pronounced in his church an anathema on Chalcedon, and accepted the Henoticon he had previously repudiated.
I didn't know you were a historian! :o)
