The Hittite Sun Disk or Hittite Sun Course is an ancient Anatolian symbol dating back to the 20th century BC.
The disks can be divided into four distinct variations. These are Semi-circular, Diamond shaped, Circular with bulls' horn and circular of semicircular with a complex design including animals and horns. The last one of those types was replicated in the Hittite Sun Course Monument. The sun disks have been found in at least 13 royal tombs from the early Bronze Age in Alaca Höyük.[1] [2]
Ankara University writes that:
The sun disk is used as the symbol of Ankara University. In 1974, it became the symbol of the Turkish capital, Ankara until it was replaced with an Islamic symbol in 1995.[3]
A monument, Hittite Sun Course Monument, to the Hittites was created by the sculptor Nusret Suman and was erected in Sıhhiye Square in 1978.
The Turkish food producing company Eti uses the sun disk as their logo.
