Example Input: Question: What material were the symbols used by the Assyrians made of? Passage:A vast number of artifacts have been discovered from ancient Mesopotamia depicting explicit heterosexual sex. Glyptic art from the Sumerian Early Dynastic Period frequently shows scenes of frontal sex in the missionary position. In Mesopotamian votive plagues from the early second millennium BC, the man is usually shown entering the woman from behind while she bends over, drinking beer through a straw. Middle Assyrian lead votive figurines often represent the man standing and penetrating the woman as she rests on top of an altar. Scholars have traditionally interpreted all these depictions as scenes of ritual sex, but they are more likely to be associated with the cult of Inanna, the goddess of sex and prostitution. Many sexually explicit images were found in the temple of Inanna at Assur, which also contained models of male and female sexual organs, including stone phalli, which may have been worn around the neck as an amulet or used to decorate cult statues, and clay models of the female vulva.
