Vincian

"I was merely a visitor to Earth, in truth I am what you'd call a "space alien"."

- Leonardo da Vinci

The Vincians are an extremely intelligent race from planet Vinci, of which "human" Italian artist/inventor, Leonardo da Vinci, was the dumbest member.

History
First contact with this species was made when Professor Hubert J. Farnsworth and Philip J. Fry crash-landed on Vinci. There they met Leonardo da Vinci, who revealed his alien nature to them. On Vinci, Leonardo was always bullied for his less than average intelligence (by Vincian standards) and thus left his planet and settled on Earth, where he became a renowned artist and inventor. Although he eventually returned home, because he couldn't stand being surrounded by people more stupid than him.

Culture and Society
They are known for amazing technology, and being great inventors. They also wear Renaissance style clothing. Their homeworld, Vinci, looks like Italy during the Renaissance period.

Biology
They are physically indistinguishable from humans, except they have an extremely long lifespan.
