Crius or Krios was the god of heavenly constellations. He was the son of Uranus and Gaia. His children were Perses, god of destruction, husband of Asteria and father of Hekate, Astraeus, husband of Eos and father of the Winds and the Planets, and Pallas, husband of Styx and father of Nike, Bia, Zelos and Cratus.
His name means "Ram" and he was associated with the start of the season, because of the constellation Aries which, in Greek mythology, was associated with ram or golden ram. Aries is known for the start of the spring in the northern hemisphere.
Crius was also known as the Pillar of the South pole. He and with his brothers; Iapetus, Hyperion and Coeus, represented the pillars of cardinal points where they held down Uranus as Cronus castrated him.(the heavens) and Gaea (the earth) apart.
Mercury (/ˈmɜːrkjʊri/; Latin: Mercurius [mɛrˈkʊrijʊs] (About this soundlisten)) is a major god in Roman religion and mythology, being one of the 12 Dii Consentes within the ancient Roman pantheon. He is the god of financial gain, commerce, eloquence, messages, communication (including divination), travelers, boundaries, luck, trickery and thieves; he also serves as the guide of souls to the underworld.
In Roman mythology, he was considered to be either the son of Maia, one of the seven daughters of the Titan Atlas, and Jupiter, or of Caelus and Dies. In his earliest forms, he appears to have been related to the Etruscan deity Turms; both gods share characteristics with the Greek god Hermes. He is often depicted holding the caduceus in his left hand. Similar to his Greek equivalent Hermes, he was awarded a magic wand by Apollo, which later turned into the caduceus, the staff with intertwined snakes.
