The chapter on Venice in Pictures from Italy -- which Dickens sets up as a long and elaborate dream -- is amazing. I'm not sure whether this is because Dickens loved Venice or because I love it (or rather, I love the idea of it, having never actually been there). I wish I could reprint the whole chapter, but a couple of excerpts will have to do.
Floating down narrow lanes, where carpenters, at work with plane and chisel in their shops, tossed the light shaving straight upon the water, where it lay like weed, or ebbed away before me in a tangled heap. Past open doors, decayed and rotten from long steeping in the wet, through which some scanty patch of vine shone green and bright, making unusual shadows on the pavement with its trembling leaves. Past quays and terraces, where women, gracefully veiled, were passing and repassing, and where idlers were reclining in the sunshine, on flag-stones and on flights of steps. Past bridges, where there were idlers too; loitering and looking over. Below stone balconies, erected at a giddy height, before the loftiest windows of the loftiest houses. Past plots of garden, theatres, shrines, prodigious piles of architecture -- Gothic -- Saracenic -- fanciful with all the fancies of all times and countries. Past buildings that were high, and low, and black, and white, and straight, and crooked; mean and grand, crazy and strong. Twining among a tangled lot of boats and barges, and shooting out at last into a Grand Canal! There, in the errant fancy of my dream, I saw old Shylock passing to and fro upon a bridge, all built upon with shops and humming with the tongues of men; a form I seemed to know for Desdemona's, leaned down through a latticed blind to pluck a flower. And, in the dream, I thought that Shakespeare's spirit was abroad upon the water somewhere: stealing through the city.
