A Gnostic revelatory monologue given in the first person by a feminine revealer called Protennoia (“First Thought”), who identifies herself in a series of self-predications and reveals her three appearances as Voice, Speech, and Logos. She reports that in her final appearance she “put on” Jesus.

The is divided into three separate discourses, each of them titled and numbered (a=1, b=2, g=3). The title, in Greek, occurs at the end: Protennoia Trimorphos (“First Thought in Three Forms”). Extant only in Coptic, Trimorphic Protennoia was originally in Greek, probably in second-century Egypt.
