He is sometime reported as a son of
Nepherites I who ruled for a brief time before being deposed by an usurper,
Psammuthes. However, this statement is based on an interpretation of a passage in the
Demotic Chronicle: His son (i.e. of Nepherites I) was allowed to succeed him. (But) a short time was vouchsafed to him... Nevertheless, the Demotic Chronicle never mentions the name of Muthis and, as pointed out by the
Egyptologist John D. Ray, "his son" could be a reference to
Hakor instead. It is also possible that Muthis was a very shadowly usurper, maybe related to the other usurper Psammuthes. Another option is that "Muthis" was simply a copying error, and therefore never existed; the latter hypothesis is supported by the fact that the name is clearly
hellenized but there are no clues of what could have originally meant "Muthis" in
Egyptian. ==Attestations==
