I came across this photo from my archives: a scan of a print taken in 1999, almost exactly 10 years ago to this day.
This is pretty much how I remember the gate but if you look at a more recent image … it’s quite different:

Though this was not my department, I specialised in Classics, esp. Greek, Ancient History and other related interests, I had many friends who attended classes in the Quadrangle: both medical and divinity students. Whoever put those two departments together had a wry sense of humor, for sure.
