The Romans borrowed religion, art, architecture and literature from the people they conquered to make a hodge-podge, eclectic culture for themselves. Mostly they borrowed from the Greeks—the Greek gods got Latin names. Ares (the god of war) became Mars. Zeus became Jupiter, Hera became Juno, Poseidon became Neptune, Aphrodite became Venus.
The Romans also borrowed technology. They measured distance the same way the Egyptians and Greeks did, by using parts of a typical grown man for standardized units.
finger—digitus (1/16 of a pes)
thumb-joint—uncia (inch, 1/12 of a pes)
four fingers—palmus (1/4 of a pes)
foot—pes (plural: pedes)
one step—gradus (2.5 pedes)
pace—passus (5 pedes)
For longer distances, a mile (mille passus) was 1000 passus or 5000 pedes. (I hope I’m getting the plurals right—https://en.wiktionary.org/wiki/passus)
