Muwatalli II
In 1280 BC a treaty between the reigning monarchs of the Hittite and Trojan states, Muwatalli II and Alaksandu of Wilusa respectively, invoked the water god, KASKAL_KUR, who was associated with an underground spring. Some scholars have linked this deity to underground springs found at Hisarlik, which would have supplied water to the citizens of the lower city.
