The clothing of peasants during the Middle Ages was very simple, while the clothing of nobility was fitted with a distinct emphasis on the sleeves of the garments. Knights adorned themselves with sleeveless "surcoats" covered with a coat of arms. Barbarian nomads wore clothing made of fur, wool, and leather. They wore long trousers, some of which had attached feet. Fine leather shoes were also worn. Imports such as turbans and silks from the East were common for the more fortunate of society.

As with today, clothing styles of medieval men changed periodically

At the end of the 13th century, the once loose and flowing tunics became tighter fitting. Besides tunics, the men also wore undershirts and briefs covered by a sleeveless jacket and an additional tunic. Stockings completed the ensemble. Men's medieval clothing also consisted of cloaks with a round opening that was slipped over the man's head. Such cloaks were worn over other clothing as a type of "jacket"

There is conflict on who invented it but it is known that the ancient Greeks did in fact use it to measure distance.

The ancient Greeks discovered and used central heating in their more important temples. Flues (the small square holes seen in the picture) were put around the temple and circulated warm air from a fire somewhere else in the temple. After the fall of Ancient Greece central heating was mostly forgotten but was rediscovered in the industrial revolution.
