The Euclid River is a river on one of the Twelve Colonies, probably on Aerelon, where Gaius Baltar spent time at as a boy, watching fish swim upstream (Home, Part I).
Notes
- The Euclid river is named after the ancient Greek mathematician Euclid, the "father of geometry."
- Given that Baltar grew up on Aerelon (as confirmed by the podcast for "Dirty Hands"), it can be assumed that the Euclid River is on Aerelon, not on Caprica.
