Is the college an Asklepieion?

After an annual introduction of new Fellows one of them viewed the neckties on display and, referring to their sagittary motif, was heard to say, 'I suppose it is the College crest.' Of course, it is precisely not that. The only crest the College has is that of its arms, which is completely different. However, one can sympathise with the new Fellow, for in the College he was surrounded by confusing reminders of the medical mythology of ancient Greece. This account is offered as a refresher course on the dramatis personae of the pantheon and some of their activities and attributes.
