The warm sun of a bright spring day, in the year of grace 1574, shone down on the beautiful city of Leyden, on its spacious squares and streets and its elegant mansions, its imposing churches, and on the smooth canals which meandered among them, fed by the waters of the sluggish Rhine. The busy citizens were engaged in their various occupations, active and industrious as ever; barges and boats lay at the quays loading or unloading, some having come from Rotterdam, Delft, Amsterdam, and other places on the Zuyder Zee, with which her watery roads gave her easy communication.
