Then with a slow ....... into the deep night. | Hyperion By John Keats | Eureka Study Aids

Then with a slow incline of his broad breast,
Like to a diver in the pearly sea,
Forward he stoop's over the airy shore,
And plung'd all noiseless into the deep night.

Then with a slow .......... into the deep night.

Context
(i) Occurrence: Book I (Lines 354-357/357)

(ii) Content: The Titans are a pantheon of gods. They include Saturn, Ops, Thea, Enceladus, Oceanus, Clymene and Hyperion. They are dethroned by the new Olympian gods and mourn at their lost empire.  Saturn is prostrate with grief. Hyperion, the sun god, is the only Titan who is still powerful. He continues his struggle but must eventually accept defeat. He is replaced by Apollo, whose emergence into godhead is perished by Mnemosyne.

Explanation

     In these lines the the speaker of the poem describes the start of journey of Hyperion from the sun to the earth. Hyperion was the only Titan who still had not been defeated by Olympians. He lived in a splendid and radiant palace and commanded the blazing sun. However, he had begun to feel mentally disturbed by certain ill-omens which seemed to indicate that even he could not feel secure and that his authority might also be threatened. Although Hyperion had formed a strong resolution to fight against Saturn, yet his mind was not at ease. In this state of mind, he heard a voice whispering into his ears. It was the voice of his aged father, Uranus. Urged by the words of his father, Hyperion got up and, leaving the planet of the sun in the charge of his father, plunged noiselessly into the deep night in order to go down to the earth to fight against Saturn and meet his fellow-Titans. In short, these lines introduce Hyperion and end the first book of the poem, Hyperion.
