According to the Roman mythographer Hyginus, Chaos and Caligine were the parents of Nox (Night), Dies, Erebus (Darkness), and Aether.[2] Cicero says that Aether and Dies were the parents of Caelus (Sky).[3] While, Hyginus says that, in addition to Caelus, Aether and Dies were also the parents of Terra (Earth), and Mare (Sea).[4] Cicero also says that Dies and Caelus were the parents of Mercury, the Roman counterpart of Hermes.[5]


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).[6][7] The corresponding Proto-Indo-European day god is Dyeus.
