Gassulawiya was the tawanannas ruling at the side of Mursili II, a king of the Hittite Empire (New kingdom) ca. 1321–1295 BC (short chronology).[1]
Gassulawiya is known to have had several children including a daughter named Massanauzzi (referred to as Matanaza in correspondence with the Egyptian king Ramesses II) married to Masturi, a ruler of a vassal state and three sons named Muwatalli, Hattusilis III and Halpasulupi. Mursili had further children with a second wife named Tanuhepa. Their names have not been recorded however.[2]
Obviously by the end of her life Gassulawiya endured severe illness, as she addressed the goddess Lilwanis with a substitute statue, in order to be relieved fromm her illness.[3]
