(aka Djeheuty, Tehuti, Tahuti, and Zehuti) is the god of wisdom, writing and the moon, the inventor of both magic and medicine, and the one who heals both Set and Horus after their contendings.

From _The Mechanics of Ancient Egyptian Magical Practice_, by R. K. Ritner, page 35:
"Thus Thoth, the god of writing, is regularly qualified as 'excellent of magic' (mnh heka) in his capacity as 'Lord of hieroglyphs' (neb medu-neter)."
His titles include "great of magic", "wise in magic" and "Lord of magic".
(From info card)
"The chief deity of medical science was Thoth, the divine scribe and patron of scholarship, who may assume the form of an ibis or baboon. Statuettes that show Thoth presenting of the Eye of Horus (wedjat) depict his mythological role as the healer of the young god, whose sight had been injured by his uncle Seth during combat for the throne."

Thoth heals both of the combatants. In TeVelde's Seth, God of Confusion, the lector-priest speaking as Thoth (Djhwty) "who reconciles the gods" declares:

The distress that causes confusion, has been driven away, and all the gods are in harmony.
I have given Horus his eye, placed the wadjet-eye in the correct position.
I have given Seth his testicles, so that the two lords are content through the work of my hands. (page 50)

(From _The Complete Gods and Goddesses of Ancient Egypt_, by Richard Wilkinson, pages 216-217)
"In his purely zoomorphic forms the baboon is somewhat more prevalent more prevalent in representations than the ibis, though representations of the god as an ibis-headed man are most common of all."

Thoth was "particularily venerated by scribes, who is is said made a small libation to the god by pouring a drop of water out of the pot in which they dipped their brushes at the beginning of each day." Amulets such as the two here would have also been carried by scribes.
