We’ve come to a turning point in the poem – after all the mourning Shelley now encourages his readers to be more cheerful and think that Adonais is in a better place (a bit like a New Orleans funeral). He now flies high over those carrion kites of reviewers and his pure spirit joined the neoplatonic Absolute, while the critic’s “cold embers choke the sordid hearth of shame” (whoa!). Adonais is not actually dead – “he hath awakened from the dream of life”, and it is us, the living, who are still asleep, fighting with phantoms and stabbing the air with our spirit’s knife. It is us who decay, consumed by fear and grief. Adonais is now past all that, as well as past all the illusory pleasures, and now can never grow old in body and spirit, and his death is not going to be like the death of those people who “with sparkless ashes load an unlamented urn”. There is a certain callousness of a young person about these lines and yet isn’t it true, we don’t feel as keenly about the death of old people as about the death of the young (let it be remembered for future visitors, I’m writing these words in the midst of the COVID-19 crisis. How aggressively would we be willing to react if the disease killed mostly young people and children?) “Death is dead, not he”, writes Shelley paradoxically, so all the elements of nature which mourned Adonais – Dawn, forests, caves and air – should stop. He is now a part of the Power which suffuses the whole nature and thus he can be felt in all nature (this stanza is really Wordsworthian). This Spirit is the force which permeates all matter, and tortures “th’unwilling dross” in order to turn it into all the beautiful shapes.
The stars keep on shining, even if they are temporarily hidden by a mist. Similarly, when a young heart is torn apart by the conflict between the elevating love and the mundane life, the illustrious dead “live there/And move like winds of light on dark and stormy air”, not letting the young man sink. Now Keats is about to join the poetic equivalent of the 27 Club, with the famous poets who died before they could fulfil their potential. He mentions Chatterton (of course), Sidney and Lucan. He didn’t realize that Keats has just started the series of what would become the most famous group of poets who died tragically young, and he himself would follow soon. There are many other poets there, he says, who are now forgotten, but their influence is lasting, like the fire which outlasts the igniting spark. Now they invite Keats to become the king of a constellation which was waiting for him.
