to start off we've got these fabulous rat men holding rats from two 15th c. manuscripts of hans vintler's flowers of virtue, giving "ratatouille but if linguini was also half-rat":
then there's this beautiful, sort of ratty woman with a mirror (whom i love very much) from the margins of a 16th c. book of hours:
the following creature is from a 1424 copy of thomas of cantimpré's liber de natura rerum. it is NOT a rat (in fact, it's supposed to be a sperpent called chelydros), but the manuscript description calls it "rat-like", which i find fitting:
here we've got a 13th c. illustration of a common bussard eating a rat (from de arte venandi cum avibus):
then there's this one 16th century book of hours that has quite a few rats in it. the catalogue description indicates that it's probably because the commissioner had like... something to do with rats. like maybe it's a name pun or something? either way, very cool rats:
then in the ormesby psalter (late 13th c.), there's this cat watching a rat hole:
and to wrap it up, here are two illustrations (c. 1450) from a collection of hebrew fables, the first showing a rat and weasels (?) running towards a trap, then the rat getting trapped:
so. that's my collection of rats in manuscripts for today :)
