Prussian King Frederick the Great's erotic poem found

An erotic poem written by Prussian King Frederick the Great has been discovered in a Berlin archive, more than 200 years after he died.

The poem is called La Jouissance, which means pleasure in a general sense, but also has a sexual connotation.

It was written in French in July 1740, a few weeks after Frederick became ruler of Prussia, a German kingdom.

He said he had written the poem to show that northern Europeans were as passionate as southerners....
