Shortly after his first wife’s death, Shelley married the daughter of William Godwin. He had lived with her almost from the date of the separation, during which time they had twice visited Switzerland. In the following year (1817), it was decreed in Chancery that Shelley was not a proper person to take charge of his two children by his first wife, who had lived with her till her death. The bill was filed in Chancery by their grandfather, Mr. Westbrook. The effects of this proceeding upon Shelley may be easily imagined. Perhaps he never recovered from them, for they were not of a nature to pass away. During this year he resided at Marlow, and wrote _The Revolt of Islam_, besides portions of other poems; and the next year he left England, not to return. The state of his health, for he had appeared to be in a consumption for some time, and the fear lest his son, by his second wife, should be taken from him, combined to induce him to take refuge in Italy from both impending evils. At Lucca he began his _Prometheus_, and wrote _Julian and Maddalo_. He moved from place to place in Italy, as he had done in his own country. Their two children dying, they were for a time left childless; but the loss of these grieved Shelley less than that of his eldest two, who were taken from him by the hand of man. In 1819, Shelley finished his _Prometheus Unbound_, writing the greater part at Rome, and completing it at Florence. In this year also he wrote his tragedy, _The Cenci_, which attracted more attention during his lifetime than any other of his works. The _Ode to a Skylark_ was written at Leghorn in the spring of 1820; and in August of the same year, the _Witch of Atlas_ was written, near Pisa. In the following year Shelley and Byron met at Pisa. They were a good deal together; but their friendship, although real, does not appear to have been of a very profound nature; for though unlikeness be one of the necessary elements of friendship, there are kinds of unlikeness which will not harmonize. During all this time, he was not only maligned by unknown enemies, and abused by anonymous writers, but attempts of other kinds are said to have been made to render his life as uncomfortable as possible. There are grounds, however, for doubting whether Shelley was not subject to a kind of monomania upon this and similar points. In 1821, he wrote his _Adonais_, a monody on the death of Keats. Part of this poem had its origin in the mistaken notion, that the illness and death of Keats were caused by a brutal criticism of his _Endymion_, which appeared in the _Quarterly Review_. The last verse of the _Adonais_ seems almost prophetic of his own end. Passionately fond of boating, he and a friend of his, Mr. Williams, united in constructing a boat of a peculiar build, a very fast sailer, but difficult to manage. On the 8th of July, 1822, Shelley and his friend Williams sailed from Leghorn for Lerici, on the Bay of Spezia, near which lay his home for the time.
