And completely off any point but the catercap remark below, a website that has pictures of just about every example of clerical and academic headgear that mankind has to offer: Klerikale Kopfbedeckungen.
Believe me, the visit will be worth the time spent scrolling down. The pictures of the Canterbury cap – the proper Kopfbedeckung of the Anglican cleric, NOT the biretta – are appreciated. But the academic doctoral headgear of the University of Coimbra – well, I’ve never seen anything quite like it.
Here is a photo – misfiled in the website’s photograph’s, I think – of a Anglican priest properly attired (on his way to preaching) in cassock, gown, tippet and Canterbury cap (catercap). Pity he’s not wearing bands as well.
