More in Orthopedics. Shoulder pain is an extremely common problem, and many people in particular experience shoulder pain at night. However, not every painful shoulder has the same cause. While treatments for causes of shoulder pain may have some overlap and similarity, there may also be important differences in treatment based on the diagnosis.
Under Floor Heating (hypocaust). Rich Roman houses had central heating which was under the floors. This heating system was called a hypocaust. The floors were supported on stacks of tiles (pilae) and hot air was circulated under the floor from a furnace stoked outside the building. Mosaic Floors. Mosaic have been found on the floors of many Roman buildings. Rich Romans decorated the floors of their main rooms with mosaics-tiny coloured stones (tesserae). These were stuck to the floor with mortar, a type of cement. Each mosaic used thousands of pieces to make a pattern. Mosaic floors were a statement of wealth and importance.
Roman Colosseum. The Roman Colosseum is the most famous monument to have survived from the classical world. It was built nearly two thousand years ago for the purpose of hosting violent gladiator games. Thousands of men and animals fought for their lives in the sandy arena. A few gladiators and warriors found glory there. Some even found fame and riches but many more died an anonymous death, providing entertainment for eager Roman spectators. The powerful associations and images evoked by the Roman Colosseum express both the majesty and might of the Roman empire. It dominates the space it occupies, towering above the surrounding Roman streets and buildings.
