Romans adapted Greek education practices, teaching boys and girls separately at home. Boys received physical training to prepare for potential military service, while girls learned skills like weaving. The Roman army was strictly male and required citizenship; soldiers served for 25 years before receiving land or pension. Romans developed technologies like central heating and straight roads. Wealthy homes and public baths used hypocaust systems with furnaces and ducts to circulate warm air. Romans believed in many anthropomorphic gods and goddesses associated with domains like agriculture, weather, and war under the leadership of gods like Jupiter, Juno, and Saturn.
