Alexander's Horse: Bucephalus

Bucephalus was Alexander's legendary horse who accompanied him like a shadow on his World conquest. Legend has it that he won it as a child by mounting and calming the large Freisian. Because of his huge size he named it Bucephalus i.e. Ox Face. 

Bucephalus died during the campaigns in India. It is widely believed that Alexander buried him in today's Jalalpur in Pakistan.
