Epiphʹany.

The time of appearance, meaning the period when the star appeared to the wise men of the East. The 6th January is the Feast of the Epiphany.

⁂ The word is not special to Christianity. One of the names of Zeus was Epĭphanes (the manifest one), and festivals in his honour were called “Epiphanies.” (Greek, epi-phaino, to shine upon, to be manifest [in creation].)
