Pan
Pan is a Greek God with the body of a small man with a goatee beard and reed pipes, and the hind-quarters and horns of a goat. He is very popular in Greek mythology. We know nearly everything about him, from his parentage, birth and childhood, through numerous adventures right up to his supposed death. In fact so much Greek writings survive that there are several versions of nearly everything about him.
He was often referred to as the youngest of the Gods, but in reality, he was probably the oldest, having been first worshipped in Arcadia, as early as the 6th century BC. Pan was born on Mount Lycaeum, in the South of modern Greece. The shepherding people depended a lot on goats, and so naturally needed a goat-god.
