Beon

Several attempts has been made to identify Beon or Bnon with an archaeologically attested ruler, but his hieroglyphic name(s) remains unidentified, and the name Βηών/Βνῶν can not be linked to an actual royal name.
The Greek letter β is also used in Greek for the number 2, written as β′. The original note in Manetho may have shown that the second king (i.e. β′) was “without name” (i.e. β′ + νώνυμος, or 2 + nonymos, ), indicating that the king's name was unknown. Perhaps a copy of the Epitome was made when the shorthand νών had become the norm, or the copyist made a careless dittographical error and corrupted the text into Βνῶν instead of β′ + νώνυμος?1
