During this time, Rossetti acquired an obsession for exotic animals, and in particular
wombats. He would frequently ask friends to meet him at the "Wombat's Lair" at the
London Zoo in
Regent's Park, and would spend hours there himself. Finally, in September 1869, he was to acquire the first of two pet wombats. This shortlived wombat, named "Top", was often brought to the dinner table and allowed to sleep in the large centrepiece of the dinner table during meals.
During these years, Rossetti was prevailed upon by friends to exhume his poems from his wife's grave. This he did, collating and publishing them in
1870 in the volume
Poems by D. G. Rossetti. They created a controversy when they were attacked as the epitome of the "fleshly school of poetry". The eroticism and sensuality of the poems caused offense. One poem, "Nuptial Sleep", described a couple falling asleep after sex. This was part of Rossetti's sonnet sequence
The House of Life, a complex series of poems tracing the physical and spiritual development of an intimate relationship. Rossetti described the sonnet form as a "moment's monument", implying that it sought to contain the feelings of a fleeting moment, and to reflect upon their meaning.
The House of Life was a series of interacting monuments to these moments — an elaborate whole made from a
mosaic of intensely described fragments. This was Rossetti's most substantial literary achievement.
In 1881, Rossetti published a second volume of poems,
Ballads and Sonnets which included the remaining sonnets from the
The House of Life sequence.
Toward the end of his life, Rossetti sank into a morbid state, darkened by his
drug addiction to
chloral and increasing mental instability, possibly worsened by his reaction to savage critical attacks on his disinterred (1869) poetry from the manuscript poems he had buried with his wife. He spent his last years as a withdrawn recluse.
On Easter Sunday, 1882, he died at the country house of a friend, where he'd gone in yet another vain attempt to recover his health, which had been destroyed by
chloral as his wife's had been destroyed by laudanum. He is buried at
Birchington-on-Sea, Kent, England. His grave is visited regularly by admirers of his life's work and achievements and this can be seen by fresh flowers placed there regularly.
