Catherine De' Medici by Honoré De Balzac

The little house of Madame de Belleville, where Charles IX. had deposited his prisoners, was the last but one in the rue de l'Autruche on the side of the rue Saint-Honore. The street gate, flanked by two little brick pavilions, seemed very simple in those days, when gates and their accessories were so elaborately treated. It had two pilasters of stone cut in facets, and the coping represented a reclining woman holding a cornucopia. The gate itself, closed by enormous locks, had a wicket through which to examine those who asked admittance. In each pavilion lived a porter; for the king's extremely capricious pleasure required a porter by day and by night. The house had a little courtyard, paved like those of Venice. At this period, before carriages were invented, ladies went about on horseback, or in litters, so that courtyards could be made magnificent without fear of injury from horses or carriages.

This fact is always to be remembered as an explanation of the narrowness of streets, the small size of courtyards, and certain other details of the private dwellings of the fifteenth and sixteenth centuries.
