The Baron in the Trees by Italo Calvino:
We had already been warned against sliding down the marble banister, to tell the truth, not out of fear that we would break a leg or an arm, because our parents never worried about that, and that’s why—I think—we never broke anything, but because as we got bigger and heavier, we might knock down the statues of our ancestors that our father had had placed on the bottom pilasters of the banisters on every flight of stairs. In fact, Cosimo had already caused a great-great-grandfather bishop to tumble, miter and all; he was punished, and from then on he learned to brake a moment before reaching the bottom of the stairs and jump down, a hairsbreadth from crashing into the statue. I, too, learned, because I followed him in everything, except that I, always more modest and prudent, jumped off halfway down the staircase, or slid down bit by bit, braking constantly. One day he went down the banister like an arrow, and who was coming up the stairs! The Abbé Fauchelafleur, strolling with his breviary open before him but with his gaze fixed on nothing, like a hen. If only he had been half asleep as usual! No, it was one of those moments that came even to him, of extreme attention, of alarm at all things. He sees Cosimo, he thinks, “Banister, statue, now he’ll bang into it, now they’ll scold me, too” (because for every one of our pranks he, too, was scolded, as not knowing how to monitor us), and he flings himself on the banister to stop my brother. Cosimo collides with the abbé, sweeps him down the banister (he was a tiny old man, all skin and bones), can’t brake, crashes into the statue of our ancestor Cacciaguerra Piovasco, a Crusader in the Holy Land, and they all collapse at the foot of the stairs, the Crusader in fragments (he was of plaster), the abbé, and him. There were endless reprimands, whippings, extra exercises, confinement with bread with cold soup. And Cosimo, who felt innocent because the fault was not his but the abbé’s, came out with that fierce invective: “I don’t care a bit about your ancestors, Father, sir!” The announcement of his vocation as a rebel.
