Dies (deity)

Dies (Latin "diēs" "day") was the personification of day Roman mythology, and the counterpart of the Greek goddess Hemera, the daughter of Nox (Night) and Scotus (Darkness).
Name.
The Latin noun "diēs" is based on the Proto-Italic accusative singular "*dijēm", itself stemming from the Proto-Indo-European root "*dyeu-", denoting the "diurnal sky" or the "brightness of the day" (in contrast to the darkness of the night). The corresponding Proto-Indo-European day god is Dyeus.
