In one work, a wife is forced to copulate with one of these animals after poisoning her husband and killing her sister. In that work, that one of these animals eats a crown of roses in order to turn back into a human. The story of Psyche and Cupid originates from that novel, which is titled for one of these animals and is the only entirely surviving Latin novel (10[2])from antiquity. (10[2])In one Aesop fable, one of these animals falls into a river when a miller and his son try carrying it to market. (-5[1])The novel (-5[1])Metamorphoses, by Apuleius, (10[1]-5[1])concerns a man who is turned into a golden specimen of this animal. For 10 points, name this stereotypically stubborn beast of burden.
