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 (-5[1])originates from that novel, which is titled for one of these (10[1])animals (10[1])and is the only entirely surviving Latin novel from antiquity. In one Aesop fable, (10[1])one of these animals falls into a river when a miller and his son try carrying it to market. (10[1])The novel Metamorphoses, by Apuleius, concerns a man who is turned into a golden (-5[1])specimen of this animal. For 10 points, name this stereotypically stubborn beast of burden.
