It appears that in ancient times before the rise of Egypt, Seth was worshiped by people in the Sahara. Recently a very interesting inscription has been found that relate to this worship.
The symbols on the engraving are written in the so-called Libyco-Berber writing which is really made up of Mande signs. Using the Vai signs we are able to read the inscriptions in the Malinke-Bambara language.
On the left side we see a figure of a cannine and on the right we have a figure of Seth. Reading the inscriptions from right to left I will decipher the writing.
Under the cannine figure we have: Be tu a ka na or "To exist obedient to the order in joy [with the] Mother".
Reading the inscriptions under the Seth figure we have reading the inscription from right to left: i lu i gyo fa yo gyo, or " Thou hold upright this divinity of the cult, [our] Father, the vital spirit of the society consecrated to (Seth's) cult".
This figure is important in relation to the Western Sahara and the Seth cult. Michael Rice, in Egypt's Making: The Origin of Ancient Egypt 5000-2000 BC, makes it clear that Seth was the god of the Southern people and that Anubis (the canine god) was the protector of the people of the South.
