True of engines that originated from the "original" Rolls Royce: jet
engines were named after rivers and piston engines named after birds
of prey.

They're back now, with the Trent series of big turbofans (as on many
777's such as American Airlines, Delta and others) for example.
The Olympus engine series originated with the Bristol Aeroplane
Company, later Bristol Siddeley and then merged with RR many years
back. Bristol engines were named after figures and places in Greek
mythology.
The Olympus engine is a *very* old design: one of the original 2-spool
turbojets designed as a military engine.
