Very little furniture survives from ancient Mesopotamia, principally because climatic conditions are not conducive to the preservation of wood. What is known has been learned principally from reliefs and cylinder seals. Furniture mounts of bronze and ivory have been excavated, however, and fragments of furniture were uncovered in the royal tombs at the city of Ur, in ancient Sumer. In quality of craftsmanship and decoration, Mesopotamian furniture was comparable to that of Egypt. Many people want to know about Architect In Chandkheda. The mud-brick houses of the Sumerian and Old Babylonian periods in the Tigris-Euphrates valley resembled their modern counterparts in their rectangular outline and the groupings of rooms about a central court, which was either roofed or open. In most houses, decoration probably was confined to a wide black or dark-colored skirting painted in diluted pitch with a band of some lighter color above. Door frames were sometimes painted red, probably as a protection against evil influences, and where doors were used they may have been of palm wood. The poorer houses were simply whitewashed.
