Robert Ranke Graves (24 July 1895 – 7 December 1985) was an English poet, translator and novelist. During his long life, he produced more than 140 works. He was the son of the Anglo-Irish writer Alfred Perceval Graves and Amalie von Ranke, a niece of the famous German historian Leopold von Ranke.

Graves considered himself a poet first and foremost. His poems, together with his translations and innovative interpretations of the Greek Myths, his memoir of the First World war, Good-bye to All That, and his historical study of poetic inspiration, The White Goddess, have never been out of print.

He earned his living from writing, particularly popular historical novels such as I, Claudius; King Jesus; The Golden Fleece; and Count Belisarius. He also was a prominent translator of Classical Latin and Ancient Greek texts; his versions of The Twelve Caesars and The Golden Ass remain popular today for their clarity and entertaining style. Graves was awarded the 1934 James Tait Black Memorial Prize for both I, Claudius and Claudius the God.

Swearing as an art is at present in low water. National passion seldom runs high, invention is numbed... The only taboo strong enough to be worth breaking is the sexual one...

"A Renaissance figure, among the most generous, self-willed, unseemly and brilliant writers of our century." --- The New York Times

Robert Grave's tongue-in-cheek treatise laments the decline of swearing and foul language in England and looks back with nostalgia at the glory days of oaths and blasphemies.

Written when Graves was teaching at Cairo University in 1926, a time when censorship in England was still in full swing, Lars Porsena is an impassioned defence of the foul-mouthed in literature and a resounding raspberry in the face of hypocrisy and puritanism.
