In ancient Greece, Aither was one of the primordial deities. Aither is the personification of the upper air. He embodies the pure upper air that the gods breathe, as opposed to the normal air breathed by mortals. His name may be the origin of the word ether. He was said to be the source of the Gods' power.

Arce was the twin sister of the Greek rainbow goddess Iris. Arce is often associated with the seldom-seen, faded second rainbow. She had iridescent wings, which Zeus eventually took off her after she betrayed the Gods of Olympus. The character is lovely, but Arce is likely to be mispronounced in English in a very unhelpful way. If you fancy this name we suggest you go with the alternate spelling Arke.

Asteria is an Anglicized spelling of the Greek Astraea or Astraia, the goddess of justice and innocence.  She became the constellation Virgo, so all forms of this name would be especially appropriate for a child born in late August or early September.

Atlas is one of those names that was previously thought too powerful for a baby boy, who would have to be strong enough to carry the world on his shoulders. Now Atlas has joined the pantheon of Greek and Roman god and goddess names in the realm of possibility, along with Mars, Zeus and Apollo.

 Atlas was one of the fast-rising names on the list in recent years in the USA, jumping from oblivion in 2012 into the Top 500 in 2015, and climbing several hundred places higher since then. Anne Heche was one of the first to make this audacious choice, but several celebrity parents have followed suit.

 As well as the mythological connection, Atlas is a cool geographical word name – perfect for the child of parents who love traveling or who hail from different parts of the globe.

Aura has an otherworldly, slightly New Age-y glow, but is beginning to sound more more like a legitimate name. In Greek and Roman mythology, Aura was the Titan of the breeze and the fresh, cool air of early morning. But at odds with her peaceful, well, aura, the mythological Aura is a tragic figure, ultimately transformed into a fountain by Zeus.
 At the end of the nineteenth century, Aura was not that unusual: she reached Number 511 on the Social Security list in 1882. Princess Aura was a character in the old comic strip Flash Gordon.
 Aura is currently popular in some areas of Central America. And for the first time since 1901, Aura has joined the US Top 1000 for girls in 2023.

Eos -- that's pronounced with a short e like eros without the r -- is the Greek Titan of the dawn. Any ancient name with a sleek modern feel has definite revival possibilities. Eos could be an inventive way to honor grandma Dawn. 
 
Eos is also a Welsh bird name that is occasionally given to girls in Wales — pleasingly the nightingale, so this name covers both morning and night.

Occasionally found in the Anglicized Benga spelling, this strong Yoruba name is a popular choice in Nigeria. American actor Gbenga Akinnagbe was born Olugbenga, which is a longer form of the name, meaning "God lifted me".

Hemera was the personification of day and one of the Greek primordial deities. She is the goddess of the daytime and,said to be the daughter of Erebus and Nyx (the goddess of night).

Hemera

She was queen of the Greek gods, both sister and wife to Zeus, but the name of her Roman counterpart Juno has become much more fashionable these days. That said, we think Hera has possibilities today too, as so many ancient goddess names rise to prominence.

More than 50 baby girls were given the name last year, about the same number as were named Eugenia. About twice that many were named Juno. Another similar mythological choice, Hero -- yes, it's a female name -- was given to only 13 baby girls.

Hera

Hesperos or Hesperus is the personification of the evening star in Greek mythology; in Roman myth, that role is held by Venus. There's a Longfellow poem called "The Wreck of the Hesperus" about a tragic ship voyage.

Iris has so much going for it. It's a fashionable flower name. It's a mythological name, from the Greek goddess of the rainbow. And it's a classic name, always ranking in the girls' Top 1000 but now at its highest point ever.
 
Iris is directly derived from the Greek word iris, meaning "rainbow." In Greek mythology, rainbow goddess Iris was a messenger for Zeus and Hera who rode the rainbow as a multicolored bridge from heaven to earth. 
 The botanical iris also carries evocative symbols. In ancient times, the Iris was considered a symbol of power and majesty, the three petal segments representing faith, wisdom and valor. This image led to the naming of the colored part of the eye.
In the contemporary world, Iris has amazing international versatility, ranking highly throughout the English-speaking world as well as in a diverse range of countries from Spain to Slovenia, France to Sweden.
 Part of Iris's rise is due to its celebrity power: Jude Law and Sadie Frost, Judd Apatow and Leslie Mann, and Renee O'Connor all chose Iris for their daughters.
 A notable modern bearer was the prolific British novelist Iris Murdoch. Frequently seen on screen, characters called Iris have been played by Jodie Foster, Jane Fonda and Kate Winslet, and Iris Chase is the narrator in the Margaret Atwood novel The Blind Assassin.

Khione was the name of several minor figures in Greek mythology, of which the most notable is the nymph who Hermes turned into a snow cloud. Khione works as both a high-brow mythological name and a Kardashian-trendy K name.

In Greek mythology, Nyx was a powerful goddess and the embodiment of the night, but when spoken, its negative meaning can't be ignored.

Selene may be the mythological Greek original, but Latin variation Selena is used more often in the US these days. Selene is the Greek goddess of the moon, sister of Helios the sun god. Selene is also sometimes called Cynthia and Phoebe. The name may be related to the word selas, which means light, and is one of the loveliest of the <a href-="https://nameberry.com/list/624/gorgeous-greek-goddess-names-for-babies">Greek goddess names</a>.

The supreme Olympian god represents a mighty image for a little fella to live up to, but more and more parents are beginning to consider it seriously.  The Roman equivalent Jupiter has also come down to earth.  And Zeus wasn't just the supreme god, he was also the god of the sky, thunder, lightning, and fate, among other weighty responsibilities.
