Aktisanes is a Nubian king who is mentioned by the Greek historian Hecataeus of Abdera.
[2] His longest text is a now lost building inscription copied by the Lepsius expedition in Nuri, but only published in 1977.
The same holds true for a doorjamb from the same place providing the full titulary of the king, but with the nomen only partly preserved.
[4] The name Gatisen has been identified with Aktisanes, known from the Greek historian Hecataeus of Abdera.
Therefore and for other reasons it is in general assumed that Hecataeus chose the name of a contemporary Nubian king as he composed his more fictional story.
