A relative humidity level between 40% and 50% is generally considered to be the most comfortable. Anywhere from 30% to 60% is acceptable, but ideally you want to avoid the extremes of that range.
Ancient Greek civilization began around 1600 BC, at Mycenae and in Crete. It ended with the annexation of Greece by Rome in 146 BC. It was at its height around 431 BC, when the Peloponnesian War between Sparta and Athens began.
The history of Greece during Classical Antiquity may be subdivided into five major periods. The earliest of these is the Archaic period (c. 800 â c. 500 BC), in which artists made larger free-standing sculptures in stiff, hieratic poses with the dreamlike archaic smile.
