Amun was a Goa'uld and the husband of Amounet. He was an underlord of Ra and was in Egypt at some point during the 12th dynasty. His Ha'tak arrived on the planet of the Goa'uld Sekhmet, when the latter decided to tighten his alliance with him, probably with the aim of recovering one of the "Arrows of Sekhmet". Following this, Amun was hit by surprise by the same Sekhmet and killed by his own First Prime Khufu. (SG1: "The DVD Collection 49")
