Sípilo
Central and southern parts of western Anatolia entered history with the still obscure Luwian kingdom of Arzawa, probably offshoots, as well as neighbors and, after around 1320 BCE, vassals of the Hittite Empire. Cybele monument located at Akpınar on the northern flank of Mount Sipylus, at a distance of from Manisa on the road to Turgutlu is, along with the King of Mira rock relief at Mount Nif near Kemalpaşa and a number of cuneiform tablet records are among the principal evidence of extension of Hittite control and influence in western Anatolia based on local principalities. Cybele monument by itself represents a step of innovation in Hittite art where full-faced figures in high relief are rare.
