Note 166 — THE THEOGONY.
George Chapman translation
Then rose Thaumas vast.] That beautiful phenomenon in the heavens, which we call the rainbow, was by the Ægyptians styled Thamuz, and signified “the wonder.” The Greeks expressed it Thaumas: and hence was derived θαυμαζω, to wonder. This Thaumas they did not immediately appropriate to the bow: but supposed them to be two personages, and Thaumas the parent. Bryant.
