water, and defensive fortifications. In order to support large buildings, they were often built on top of foundation platforms or on mud brick foundations. Floors were typically made of rammed earth, covered in important rooms with carpets or reed mats. Floors in locations that were exposed to the elements, such as outside on terraces or in courtyards, were paved with stone slabs or backed bricks. Roofs, particularly in larger rooms, were supported through the use of wooden beams. The ancient Assyrians accomplished several technologically complex construction projects, including constructions of whole new capital cities, which indicates sophisticated technical knowledge. Though in large part following previous Mesopotamian architecture, there are several characteristic features of ancient Assyrian architecture. Some examples of features of ancient Assyrian architecture include stepped merlons, vaulted roofs, and palaces to a large degree often being made up of sets of self-contained suites. Art A relatively large number of statues and figurines have been recovered from the ruins of temples in Assur dating to the Early Assyrian period. Most of the surviving artwork from this time was clearly influenced by the artwork of foreign powers. For instance, a set of 87 alabaster figures of male and female worshippers from Assur before the rise of the Akkadian Empire greatly resembles Early Dynastic Sumerian figures. Because of variation in artwork elsewhere, the artwork of early Assur was also highly variable depending on the time period, ranging from highly stylized to highly naturalistic. Among the most unique finds from the Early period is the head of a woman of which her eyes, eyebrows, and elaborate hair covering were originally inlaid. This head is typical of the art style of the Akkadian period, with an overall naturalistic style, smooth and soft curves and a full mouth. Another unique art piece from the early period is an ivory figurine of a nude woman, and fragments of at least five additional similar figurines. The ivory used might have come from Indian elephants, which would indicate trade between early Assur and the early tribes and states of Iran. Among other artwork known from the early period are a handful of large stone statues of rulers (governors and foreign kings), figures of animals, and stone statues of naked women. The artwork known from the Old Assyrian period, other than a few objects such as a partial stone statue perhaps depicting Erishum I, is largely limited to seals
