its a great hymn to a great and powerful God, Ouranos, Progenitor of the Titans and Gods alike. Husband to Gaia,, one of the Protogenoi.

Great Heav’n [Ouranos], whose mighty frame no respite knows, father of all, from whom the world arose:
Hear, bounteous parent, source and end of all, forever whirling round this earthly ball;
Abode of Gods, whose guardian pow’r surrounds th’ eternal World with ever during bounds;
Whose ample bosom and encircling folds the dire necessity of nature holds.
Ætherial, earthly, whose all-various frame azure and full of forms, no power can tame. 
All-seeing Heav’n, progenitor of Time [Kronos], forever blessed, deity sublime,
Propitious on a novel mystic shine, and crown his wishes with a life divine.

Ouranos is the personification of the sky, like Gaia is the personification of the Earth. Back then, ancient Greeks thought that Earth, Sea and Sky were different deities, but we know now that it is all part of the same planet called Earth. The sky, where the Gods of Olympos have their abode. One thing that stands out here is that He is called Progenitor of Kronos. Kronos was His youngest son but Khronos was the personification of Time and later one Khronos and Kronos became one God. Which was not uncommon. More powerful deities absorded other deities into them. Plouton with Thanatos, Kronos with Khronos. Ouranos’ other name Akmon could have been another local deity absorded by Ouranos’ cult. The Romans called Him Caelum. So far i can tell, he did not have any epithets, nor not much of a cult either. He could have had shrines. In myths except for the Theogony, and the creation myths, He doesn’t seem to play much of a great role. After His castration by His youngest son Kronos, he doesn’t seem to show up again when Rhea asked for advice of Her divine parents regarding Kronos swallowing their kids.
