Jumar is a supposed hoofed mammal of Western Europe (Southern France; Italy). Mulelike. Head is like a bull’s. Said to have small, knobby horns. Black eyes.Neapolitan physicist Giambattista della Porta saw apparent mule x bull hybrids in Ferrara, Italy, in the sixteenth century.
- Konrad Gesner’s suggestion that the Jumar is a Donkey (Equus asinus) x Bull (Bos taurus) hybrid is impossible, since the offspring would involve a mating between two separate ungulate orders, the artiodactyls and perissodactyls.
- The comte de Buffon supervised the dissection of two alleged Jumars but found them to be small donkeys.
