the familiar 'rabbit/hare trinity' -- here labelled "Unser seindt vier" [We are four/there's four of us]. from the album amicorum of Frederick IV of the Palatine [UB Heidelberg, Pal. Ger. 619 -- this is f.47v. entries are dated 1582-1605]. Here we have an interesting association with the motif of the 2 fools who say "we are three" -- making the viewer by his/her puzzled inquiry the 3rd! The hare also has traditional associations of folly -- cf. Eng. "mad as a march hare"
