By the middle of the sixteenth century the scene has changed. Much blood has flowed through the arches of time; and now the conqueror has learnt from the Church to be merciful, from nascent science to be strong. He can spread peace wherever his sword reaches; and fear that of old ruled all under the sun, now can walk only in dark places. Walls no longer bring comfort, and soon they are to be thrown down to make way for the broad streets which will carry the movement outwards; and, most significant change, the country house with 'its gardens and its gallant walks' takes the place of the grange. From the thraldom of terror what an escape, to light, air, freedom, activity! The gates of joy are opened, the private citizen learns to live, to follow choice not necessity, to give the reins to his spirit and take hold on the gifts that Nature spreads before him. In the pursuit of peace, human progress has lain in the enlargement of the units of government capable of holding together; from villages to towns, from towns to provinces, from provinces to nations. The last step had been the achievement of the Middle Ages, though even by the end of the fifteenth century it was not yet complete: the twentieth century finds us reaching forward to a new advance. We have spoken of Erasmus' efforts to bring back peace from her exile, of the experiences of his youth when Holland had wept for her children. In 1517, when he wrote his 'Complaint of Peace cast forth from all lands', he was a man and one of Charles' councillors; but Holland was still weeping and refusing comfort. She had good reason. The provinces of the Netherlands were disunited, no sway imposed upon them with strength enough first to restrain and then to knit together. On either side of the Zuider Zee lay two bitter enemies: Holland, which had accepted the Burgundian yoke, and Friesland, which after a long struggle against foreign domination, had been reduced by the rule of Saxon governors, Duke Albert and Duke George. To the south was Gueldres, which, under its Duke, Charles of Egmont, had thrown in its lot with France against Burgundy, and was continually instigating the subjugated Frieslanders to rebellion. Then was war in the gates. This was the kind of thing that happened. In 1516, after a fresh outbreak of the ceaseless struggle, Henry of Nassau, Stadhouder of Holland and Zeeland, ordered that all Gueldrians or Frieslanders who showed their faces in his dominions should be put to death; and some who were resident at the Hague were executed on the charge of sending aid to their compatriots. A raid by the Gueldrians ended in the massacre of Nieuwpoort. Nassau replied by ravaging the country up to the walls of Arnhem, the Gueldres capital.
