The Greek ἔρως, meaning ‘desire’, comes from ἔραμαι ‘to desire, love’, of uncertain etymology. R. S. P. Beekes has suggested a Pre-Greek origin.[6]
According to Hesiod‘s Theogony (c. 700 BC), one of the most ancient of all Greek sources, Eros (the god of love) was the fourth god to come into existence, coming after Chaos, Gaia (the Earth), and Tartarus (the abyss).[14]
According to Oxford languages, primordial /prʌɪˈmɔːdɪəl/: existing at or from the beginning of time; primeval.
According to wikipedia:
In Greek mythology, the primordial deities are the first generation of gods and goddesses. These deities represented the fundamental forces and physical foundations of the world and were generally not actively worshiped, as they, for the most part, were not given human characteristics; they were instead personifications of places or abstract concepts.
In ancient Greek religion and mythology, Phoebe (/ˈfiːbi/FEE-bee; Ancient Greek: Φοίβη, romanized: Phoíbē, associated with φοῖβος phoîbos, “shining”) was one of the first generation of Titans, who were one set of sons and daughters of Uranus and Gaia.[1] She was the grandmother of the sun , the moon goddessArtemis, and the witchcraft goddess Hecate. According to myth, she was the original owner of the Oracle of Delphi before gifting it to her grandson Apollo. Her name, meaning “bright”, was also given to a number of lunar goddesses like Artemis and later the Roman goddesses Luna and Diana, but Phoebe herself was not actively treated as a moon goddess on her own right in ancient mythology.
Phoebe is a Titaness, one of the twelve (or thirteen) divine children born to Uranus (Sky) and Gaia (Earth). Phoebe’s consort was her brother Coeus, with whom she had two daughters, first Leto, who bore Apollo and Artemis, and then Asteria, a star goddess who bore an only daughter, Hecate.[5]Hesiod in the Theogony describes Phoebe as “χρυσοστέφανος” (khrysostéphanos, meaning “golden-crowned”)
In Greek mythology, Theia (/ˈθiːə/; Ancient Greek: Θεία, romanized: Theía, lit. ‘divine’, also rendered Thea or Thia), also called Euryphaessa (Ancient Greek: Εὐρυφάεσσα) “wide-shining”, is one of the twelve Titans, the children of the earth goddessGaia and the sky godUranus. She is the Greek goddess of sight and vision, and by extension the goddess who endowed gold, silver and gems with their brilliance and intrinsic value.[2] Her brother-consort is Hyperion, a Titan and god of the sun, and together they are the parents of Helios (the Sun), Selene (the Moon), and Eos (the Dawn). She seems to be the same with Aethra, the consort of Hyperion and mother of his children in some accounts.[3] Like her husband, Theia features scarcely in myth, being mostly important for the children she bore, though she appears in some texts and rare traditions.
Rhea or Rheia (/ˈriːə/;[2]Ancient Greek: Ῥέα [r̥é.aː] or Ῥεία [r̥ěː.aː]) is a mother goddess in ancient Greek religion and Greek mythology, the Titaness daughter of the earth goddessGaia and the sky godUranus, himself a son of Gaia. She is the older sister of Cronus, who was also her consort, and the mother of the five eldest Olympian godsHestia, Demeter, Hera, Poseidon and Zeus, and the king of the Underworld, Hades. But Cronus learnt that he was destined to be overthrown by one of his children like his father was before him, so he swallowed all the children Rhea bore as soon as they were born. When Rhea had her sixth and final child, Zeus, she spirited him away and hid him in Crete, giving Cronus a rock to swallow instead, thus saving her youngest son who would go on to challenge his father’s rule and rescue the rest of his siblings.
Cronus was usually depicted with a harpe, scythe or a sickle, which was the instrument he used to castrate and depose Uranus, his father. In Athens, on the twelfth day of the Attic month of Hekatombaion, a festival called Kronia was held in honour of Cronus to celebrate the harvest, suggesting that, as a result of his association with the virtuous Golden Age, Cronus continued to preside as a patron of the harvest. Cronus was also identified in classical antiquity with the Roman deitySaturn.
