There are two from Samuel Beckett in the 100: from Murphy and The Unnamable. However, for my first choice, I have selected his final prose work Stirrings Still:
One night as he sat at his table head on hands he saw himself rise and go.The movement back or forth is everything. It draws one back, in, and it sets one free. This is why I disagree with CM's evaluation of Proust's famous opening line - that is famous only because of what it precedes. No. It goes back and forth. It encompasses the novel to come.
My second and third choices are by the same author, Peter Handke, both translated by Ralph Manheim.
I shut my eyes and out of the black letters the city lights took shape. Across.For my final choice, I was tempted by the two and a half page sentence hurling us into Thomas Bernhard's Yes, solely for its hilarious, horrendous excess. But I ran out of patience copying it. So instead I chose my real favourite, the first line of Extinction as translated by the late David McLintock.
A quarter of a century, or a day, has passed since I arrived in Jesenice on the trail of my missing brother. Repetition.
On the twenty-ninth, having returned from Wolfsegg, I met my pupil Gambetti on the Pincio to discuss arrangements for the lessons he was to receive in May, writes Franz-Josef Murau, and impressed once again by his high intelligence, I was so refreshed and exhilerated, so glad to be living in Rome and not in Austria, that instead of walking home along the Via Condotti, as I usually do, I crossed the Flaminia and the Piazza del Popolo and walked the whole length of the Corso before returning to my apartment in the Piazza Minerva, where at about two o’clock I received the telegram informing me that my parents and my brother, Johannes, had died.
