This is the higher one of two tower-like structures with a praying woman on its side, both interpreted as libation vessels. 16th Century BC, early Mitanni period. From Wikipedia: "Mitanni (c. 1550–1260 BC), earlier called Ḫabigalbat in old Babylonian texts, c. 1600 BC; Hanigalbat or Hani-Rabbat in Assyrian records, or Naharin in Egyptian texts, was a Hurrian-speaking state in northern Syria and southeast Anatolia (modern-day Turkey) with Indo-Aryan linguistic and political influences." I did not take a picture of the other.
