Final answer:
The question does not correspond to a factual context, as the Epic of Gilgamesh is engraved on tablets of clay, not on types of stones like granite, marble, or sandstone. However, ancient texts are found on various materials, including gypsum alabaster for the stele of Ushumgal and granodiorite for the Rosetta Stone.
Step-by-step explanation:
The talk of Gilgamesh is not literally carved into a type of stone like granite, marble, limestone, or sandstone. The Epic of Gilgamesh is an ancient Mesopotamian poem that is often inscribed on tablets made from various materials. However, the stele mentioned with an inscription featuring Ushumgal is made from gypsum alabaster, and texts such as the Akkadian inscriptions or the Rosetta Stone have utilized materials such as granodiorite or limestone, respectively. Moreover, cylinder seals, which were used in Ancient Near Eastern societies, were commonly made from materials including agate, lapis lazuli, and limestone, showing the diverse use of stone in these civilizations.
