Urn

Urn is an Ephebian philosopher, who appears in Small Gods, and works for his uncle Didactylos. He is of a more practical turn than his uncle, sometimes causing friction between the two.

Urn has an interest in mathematics, mechanics and physics, and was the inventor of the Discworld's first combustion engine, which he installed on short-lived The Unnamed Boat.

Annotations

His name refers to the pun "What's a Grecian urn?" (answer: "about 10 drachma an hour").

The fact that he is a nephew may link him to Ern, PC Theolophius "Clear-Orf" Goon's nephew in Enid Blyton's Five Find-Outers and Dog Mysteries...
