Poimandres (Greek: Ποιμάνδρης; also known as Poemandres, Poemander or Pimander) is the first tractate in the Corpus Hermeticum, named after its main character Poimandres, the nous of a supreme deity.
Originally written in Greek, the title was formerly understood to mean "shepherd of men" from the words ποιμήν and ἀνήρ.
Griffith, proposed that it is actually derived from the Coptic phrase ⲡⲉⲓⲙⲉ ⲛ̅ⲧⲉ ⲣⲏ peime nte rē meaning "the knowledge of Re" or "the understanding of Re".
[1] Poimandros (Ποίμανδρος) of Greek mythology was the son of Chaeresilaus and Stratonice.
The character Poimandres can be considered to be a sort of deity, or attribute of God as nous or "mind" as expressed in the following translations.
