Austin Dobson in A Bookman’s Budget (1917) claims the longest sentence ever written in English can be found in William Hazlitt’s Spirit of the Age; Or Contemporary Portraits (1825), in the essay devoted to “Mr. Coleridge.” Dobson tells us: “Writing of Coleridge, he contrives to spin out a single sentence to one hundred and ten lines. It contains the word ‘and’ ninety-seven times, with only one semi-colon.”
You can find this tour de force of bloviation about midway through the essay, with the paragraph beginning “Next, he was engaged with Hartley’s tribes of mind . . .” and concluding with the line quoted from Coleridge: “In Philarmonia’s undivided dale!” By my count that’s about 840 words. Hazlitt is usually a forceful writer. His sentences have the quality he most admired, gusto. I take this uncharacteristic monstrosity as a parody of Coleridge’s gaseous manner. Hazlitt begins his essay like this: “The present is an age of talkers, and not of doers,” and continues, “If Mr. Coleridge had not been the most impressive talker of his age, he would probably have been the finest writer . . .”
Hazlitt is the poet-in-prose of resentment and humiliation, about which he wrote not theoretically but from unhappy experience. He was ridiculous about women and forever scrambling after money. His sentences glow with autobiographical heat. He even managed to alienate some of his closest friends. His readers appreciate his prickliness. Hazlitt’s indulgence in linguistic gigantism, of course, was surpassed with the coming of modernism. Consider Molly Bloom’s monologue and dozens of serpentine sentences in Proust.
