Ushas in the context of "Hausos"

In ancient Greek mythology and religion, Eos (/ˈiːɒs/; Ionic and Homeric Greek Ἠώς Ēṓs, Attic Ἕως Héōs, "dawn", pronounced [ɛːɔ̌ːs] or [héɔːs]; Aeolic Αὔως Aúōs, Doric Ἀώς Āṓs) is the goddess and personification of the dawn, who rose each morning from her home at the edge of the river Oceanus to deliver light and disperse the night. In Greek tradition and poetry, she is characterized as a goddess with a great sexual appetite, who took numerous human lovers for her own satisfaction and bore them several children. Like her Roman counterpart Aurora and Rigvedic Ushas, Eos continues the name of an earlier Indo-European dawn goddess, Hausos. Eos, or her earlier Proto-Indo-European (PIE) ancestor, also shares several elements with the love goddess Aphrodite, perhaps signifying Eos's influence on her or otherwise a common origin for the two goddesses. In surviving tradition, Aphrodite is the culprit behind Eos's numerous love affairs, having cursed the goddess with insatiable lust for mortal men.

In Greek literature, Eos is presented as a daughter of the Titans Hyperion and Theia, the sister of the sun god Helios and the moon goddess Selene. In rarer traditions, she is the daughter of the Titan Pallas. Each day she drives her two-horse chariot, heralding the breaking of the new day and her brother's arrival. Thus, her most common epithet of the goddess in the Homeric epics is Rhododactylos, or "rosy-fingered", a reference to the sky's colours at dawn, and Erigeneia, "early-born". Although primarily associated with the dawn and early morning, sometimes Eos would accompany Helios for the entire duration of his journey, and thus she is even seen during dusk.

Pururavas (Sanskrit: पुरूरवस्, Purūravas) is a character in Hindu literature, a king who served as the first of the Lunar dynasty.

According to the Vedas, he is a legendary entity associated with Surya (the sun) and Usha (the dawn), and is believed to reside in the middle region of the cosmos. The Rig Veda (X.95.18) states that he was a son of Ilā and was a pious ruler. However, the Mahabharata states that Ila was both his mother and his father. According to the Vishnu Purana, his father was Budha, and he was ancestor of the tribe of Pururavas, from whom descended the Yadavas, Kauravas, and Pandavas of Mahābhārata.

Aurora (/ɔːˈrɔːrə/ or /əˈrɔːrə/; Latin: Aurōra, Latin pronunciation: [au̯ˈroːra]) is the Latin word for dawn, and the goddess of dawn in Roman mythology and Latin poetry.Like Greek Eos and Rigvedic Ushas, Aurora continues the name of an earlier Indo-European dawn goddess, Hausos.

Ratri (Sanskrit: रात्रि, lit. 'night', IAST: Rātri; also referred to as Nisha), is a Vedic goddess in Hinduism. She is the personification of the night. The majority of references to Ratri are found in Rigveda and she is described as the sister of Ushas, the personification of dawn. Together with Ushas, she is referred to as a powerful mother and strengthener of vital power. She represents cyclic rhythmic patterns of the cosmos. Her physical appearance isn't explicitly mentioned, but she is described as a beautiful maiden.

One hymn in the Rigveda and five hymns in the Atharvaveda are dedicated to her. In later Tantric texts she occupies an important position. She is associated with Ushas, Indra, Rta, Satya in Rigveda, whereas in Atharvaveda she is associated with Surya. The Brahmanas and the Sutra literature often mention Ratri.
