The Three Cities, Rome Volume IV by Émile Zola

IT was ten o'clock when Pierre and Narcisse, after dining at the Caffe di Roma, where they had long lingered chatting, at last walked down the Corso towards the Palazzo Buongiovanni. They had the greatest difficulty to reach its entrance, for carriages were coming up in serried files, and the inquisitive crowd of on-lookers, who pressed even into the roadway, in spite of the injunctions of the police, was growing so compact that even the horses could no longer approach. The ten lofty windows on the first floor of the long monumental facade shone with an intense white radiance, the radiance of electric lamps, which illumined the street like sunshine, spreading over the equipages aground in that human sea, whose billows of eager, excited faces rolled to and fro amidst an extraordinary tumult.

And in all this there was not merely the usual curiosity to see uniforms go by and ladies in rich attire alight from their carriages, for Pierre soon gathered from what he heard that the crowd had come to witness the arrival of the King and Queen, who had promised to appear at the ball given by Prince Buongiovanni, in celebration of the betrothal of his daughter Celia to Lieutenant Attilio Sacco, the son of one of his Majesty's ministers. Moreover, people were enraptured with this marriage, the happy ending of a love story which had impassioned the whole city: to begin with, love at first sight, with the suddenness of a lightning-flash, and then stubborn fidelity triumphing over all obstacles, amidst romantic circumstances whose story sped from lip to lip, moistening every eye and stirring every heart.
