What is "humban-numena"

Humban-Numena (or Kumban-Numena) was a king of Elam from the Igihalkid dynasty (Middle Elamite period, mid-14th century BCE). He was a son and the successor of Attar-kittah, as it is attested in his inscriptions from the temple in Lyian and in Susa. He is mentioned as the father of King Untsah-Napirisha in a later inscription of King Shilhak-Inshushinak. According to a Neo-Babylonian copy of a letter from an Elamite king to the Babylonian court (the so-called the Berlin letter), he married a daughter of Babylonian King Kurigalzu or a daughter of his uncle, Elamite King Pahir-ishsha.
