Horwennefer
Horwennefer, also known as Hurganophor, Haronnophris, Harmachis, Hyrgonaphor, Herwennefer, or Hugronaphor, was an Upper Egyptian of apparently Nubian origin who led Upper Egypt in secession from the rule of Ptolemy IV Philopator in 205 BC. No monuments are attested to this king but along with his successor Ankhwennefer he held a large part of Egypt until 186 BC. A graffito dating to about 201 BC on a wall of the mortuary Temple of Seti I at Abydos, in which he is called by the Greek name Hyrgonaphor, is an attestation to the extent of his influence. He appears to have died before 197 BC.
The Abydene graffito, one of the few documents remaining from his reign, is written in Egyptian using Greek letters, the oldest testimony of a development which would end in the Coptic script replacing the native Egyptian demotic.
