Camels
The Grand Medieval Bestiary: Animals in Illuminated Manuscripts

Camels appear in bestiaries and in scenes that are intended to evoke some manner of Eastern transport; several biblical characters, including the Three Kings in the Adoration of the Magi, are often depicted with camels, either riding camels or using the camels as beasts of burden.

As with elephants and other exotic creatures, however, many Western European artists and illustrators had not actually seen camels for themselves, so the depictions ranged in accuracy somewhat. Sometimes they look like odd-looking horses with long necks; most illustrators remember to add bumps of some sort to the animal's back.
