Today's Roman fact.
Don't you just love it when you walk into your bathroom on a cold morning, and the floor is warm and cozy?
Well, that was a Roman invention, central heating to be exact.
Romans didn’t like to be cold so they invented central heating, called hypocaustum in Latin. It was a simple system of circulating hot air from the furnace through hollowed floors and walls. The earliest mention of it was from around 350 BC, and this invention was an important improvement of living conditions of citizens and the hygiene in general. But because of its cost, it was limited to the wealthier class. It was also quite common in hot baths and other public buildings.
