Of the work upon which he was now engaged, the narrative-poem of _Endymion_, we may give his own account to his little sister Fanny in a letter dated September 10th, 1817:--
'Perhaps you might like to know what I am writing about. I will tell you. Many years ago there was a young handsome Shepherd who fed his flocks on a Mountain's Side called Latmus--he was a very contemplative sort of a Person and lived solitary among the trees and Plains little thinking that such a beautiful Creature as the Moon was growing mad in Love with him.--However so it was; and when he was asleep she used to come down from heaven and admire him excessively for a long time; and at last could not refrain from carrying him away in her arms to the top of that high Mountain Latmus while he was a dreaming--but I dare say you have read this and all the other beautiful tales which have come down from the ancient times of that beautiful Greece.'
On his return to London he and his brother Tom, always delicate and now quite an invalid, took lodgings at Hampstead. Here Keats remained for some time, harassed by the illness of his brother and of several of his friends; and in June he was still further depressed by the departure of his brother George to try his luck in America.
In April, 1818, _Endymion_ was finished. Keats was by no means satisfied with it but preferred to publish it as it was, feeling it to be 'as good as I had power to make it by myself'.--'I will write independently' he says to his publisher--'I have written independently _without judgment_. I may write independently and _with judgment_ hereafter. In _Endymion_ I leaped headlong into the sea, and thereby have become better acquainted with the soundings, the quicksands, and the rocks, than if I had stayed upon the green shore, and piped a silly pipe, and took tea and comfortable advice.' He published it with a preface modestly explaining to the public his own sense of its imperfection. Nevertheless a storm of abuse broke upon him from the critics who fastened upon all the faults of the poem--the diffuseness of the story, its occasional sentimentality and the sometimes fantastic coinage of words,[xiii:1] and ignored the extraordinary beauties of which it is full.
Directly after the publication of _Endymion_, and before the appearance of these reviews, Keats started with a friend, Charles Brown, for a walking tour in Scotland. They first visited the English lakes and thence walked to Dumfries, where they saw the house of Burns and his grave. They entered next the country of Meg Merrilies, and from Kirkcudbrightshire crossed over to Ireland for a few days. On their return they went north as far as Argyleshire, whence they sailed to Staffa and saw Fingal's cave, which, Keats wrote, 'for solemnity and grandeur far surpasses the finest Cathedral.' They then crossed Scotland through Inverness, and Keats returned home by boat from Cromarty.
His letters home are at first full of interest and enjoyment, but a 'slight sore throat', contracted in 'a most wretched walk of thirty-seven miles across the Isle of Mull', proved very troublesome and finally cut short his holiday. This was the beginning of the end. There was consumption in the family: Tom was dying of it; and the cold, wet, and over-exertion of his Scotch tour seems to have developed the fatal tendency in Keats himself.
From this time forward he was never well, and no good was done to either his health or spirits by the task which now awaited him of tending on his dying brother. For the last two or three months of 1818, until Tom's death in December, he scarcely left the bedside, and it was well for him that his friend, Charles Armitage Brown, was at hand to help and comfort him after the long strain. Brown persuaded Keats at once to leave the house, with its sad associations, and to come and live with him.
Before long poetry absorbed Keats again; and the first few months of 1819 were the most fruitful of his life. Besides working at _Hyperion_, which he had begun during Tom's illness, he wrote _The Eve of St. Agnes_, _The Eve of St. Mark_, _La Belle Dame Sans Merci_, and nearly all his famous odes.
Troubles however beset him. His friend Haydon was in difficulties and tormenting him, poor as he was, to lend him money; the state of his throat gave serious cause for alarm;
