*Hemphta* is the name of the deity.

The Latin *Numen triforme* means “threefold deity,” or “god having three forms.”

The Greek actually appears to say παντόμορφον (pantómorphon), which I take to mean “all-formed” or something to that effect.

The image (specifically the right version) is from Athanasius Kircher's [Oedipus Aegyptiacus][1], a treatise on Egyptology, [volume 2, part 2, p. 160][2] (1653 edition). I am not sure what Kircher's idea of this Egyptian religious concept was exactly, but he writes a little more about it in [part 1, p. 160][3], and if I understand him right, the deity is known as *Hemphta*, *Phta* and *Amun*, and he believes that it is an obscured, imperfect representation of the Holy Trinity of Christian doctrine («Sacrosanctam & ter benedictam Triadem, fidei Christianae mysterium uti maximum, sic sublimissimum, nullo non tempore etiam sub obscuris fabularum figmentis adumbratum esse»).
