Heka Sightings

Pyramid Texts 2400BC - 2300BC
Here, Heka's not the nicest guy around. As the personification of all magic, he teams up with the king, whose own magic increases when he takes a bite out of other people. Apparently, dead people get stronger if they nibble on others.
Coffin Texts, Spell 261 2181BC - 2055BC
Heka gets groovy with the creator of the universe. In fact, he boasts that he was hanging out with the gods from the very beginning, before it became cool. That's one powerful dude, all right.
The Book of the Dead (The Papyrus of Ani) 1300BC
Heka pops up in the abstract sense in Chapter XXIV. Here, he's the all-around power of "magic," rather than a god per se. But the dead need their wizards, so who knows? Elsewhere, he is a god that the dead calls on.
The Instruction of Khety for His Son Merikare 2030BC - 1640BC
An ancient king, Khety, decided to leave some wisdom for his son. He describes "heka," or magic, as a weapon that men can use to influence events as they please. Heka himself was number one on Khety's MySpace friends list.
The Song of the Nile by Stephanie Dray 2011
The heroine of this book, Cleopatra Selene (daughter of the most famous Cleopatra) knows quite a bit about magic, so she isn't surprised when Heka, in his abstract form, shows up quite a bit. After all, what would a pharaoh's reign be without a magic surprise?
