Various representations of wrestlers have been found on stone slabs recovered from the Sumerian civilization.[7] One showing three pairs of wrestlers was generally dated to around 3000 BCE.[8] A cast Bronze figurine,[9] (perhaps the base of a vase) has been found at Khafaji in Iraq that shows two figures in a wrestling hold that dates to around 2600 BCE. The statue is one of the earliest depictions of sport and is housed in the National Museum of Iraq.[10][11] The origins of boxing have also been traced to ancient Sumer.[8] The Epic of Gilgamesh gives one of the first historical records of sport with Gilgamesh engaging in a form of belt wrestling with Enkidu. The cuneiform tablets recording the tale date to around 2000 BCE, however the historical Gilgamesh is supposed to have lived around 2800 to 2600 BCE.[12] The Sumerian king Shulgi also boasts of his prowess in sport in Self-praise of Shulgi A, B and C.[12] Fishing hooks not unlike those made today have been found during excavations at Ur, showing evidence of angling in Sumer at around 2600 BCE.[13]
