The Silmarillion

This is crack for any history fan. A true masterpiece of fictional worldbuilding.

Although definitely noticed this time that possibly the most old fashioned British influence over this whole mythos is the complete avoidance of anything overtly sexual in Tolkiens stories. When you compare his myths to their obvious forebear, the Greek Gods, you realise how much sex has been left out.

This isn't in itself a bad thing, but you'd be hardpressed to find any genuine historical myth from around the world that so thoroughly ignored one of the biggest features of human nature.
