From The Guardian:
The most intriguing aspect of George Eliot's life has to be her honeymoon in Venice, in the summer of 1880. Her decision, at the age of 60, to marry John Cross, a young friend some 20 years her junior, had excited disapproval among friends and acquaintances, not least because GH Lewes, with whom she had enjoyed a long and loving relationship, had been dead for less than two years. Like Dorothea in Middlemarch, who begins to love Will Ladislaw while she is still married to Casaubon, Eliot had been delighted by Cross's youth and devotion long before Lewes's death. But their honeymoon punctured the fantasy for both when Cross leaped from the balcony of their hotel suite, sailing over three or four gondolas before landing in the middle of the Grand Canal. He was rescued and carried back to his room unharmed.
Tongues started wagging. Had Cross been in flight from the sexual demands of his older wife? “One could say he had a lucky escape!” wrote an Italian journalist with unconscious irony. Was it true Cross had begged the gondoliers not to drag him out of the canal? Brenda Maddox, in her jaunty sketch of Eliot's life, believes Cross was suffering from a recurrence of severe depressive illness. She also thinks that the marriage was unconsummated. It was, in any case, short-lived. Eliot was dead and buried in Highgate cemetery in just six months. Cross – “George Eliot's widow”, as he was unkindly known – became the keeper of the flame, producing a biography of his late wife that enshrined her as a sibyl and earnest talking head, leaving one critic to bemoan the absence of the “salt and spice” of Eliot's life.
