Round houses were all over the place in ancient and not-so-ancient times. Discussing archeological sites in the region that now includes Iran and parts of Iraq, an Iranian studies professor explains –
Hallan Jemi, on a tributary of the upper Tigris in the foothills of eastern Turkey, is the oldest pre-pottery Neolithic site in the region. People lived in round houses with stone bases, and may have been among the first to domesticate pigs, an animal that was introduced at Iranian sites only toward the end of the Neolithic . . . . Zawi Chemi Shanidar was small settlement with stone-based round houses in Iraqi Kurdistan. The site is roughly contemporary with Hallan Jemi, as indicated by a single radiocarbon date of 10,800 B.P . . . . The construction of round houses is typical of the earliest communities in the Near East, none of which has unequivocal evidence for the growing of crops or for domesticated herd animals.
