Satyrus (Medieval Bestiary)
Satyrus (also known as callitrix or cericopithicus) is a species of ape described in some medieval bestiaries. It is said to always give birth to twins. Of these twins, it hates one, but loves the other. Tall and always walking erect, they were gifted with the ability to play musical instruments.
Their faces were described as being ''very human''. The Satyrus also only gave birth to Twins (multiples). The oddity is that one of the Twins will love the other, while the second will hate this one. Many sightings were claimed by The Spanish throughout their initial explorations in South America.
