The Ancients heavily relied on the stonemason to build the most impressive and long-lasting monuments to their civilizations. The Egyptians built their pyramids, the civilizations of Central America had their step pyramids, the Persians their palaces, the Greeks their temples, and the Romans their public works and wonders (See Roman Architecture). People of the Indus Valley Civilization, such as at Dholavira made entire cities characterized by stone architecture. Among the famous ancient stonemasons is Sophroniscus, the father of Socrates, who was a stone-cutter.
