To make his sovereign abroad as great as at home, he took advantage of the nice balance of power existing on the Continent. "Nothing pleases him more than to be called the arbiter of Christendom," wrote Giustiniani, and such, in fact, he very nearly was. His diplomatic gifts were displayed with immense show during the summer of 1520, when Henry met both Francis and Charles V, and promised each secretly to support him against his rival. The camp where the royalties of France and England met, near Guines, amid scenes of pageantry and chivalry so resplendent as to give it the name of The Field of Cloth of Gold, saw an alliance cemented by oath, only to be followed by a solemn engagement between Henry and Charles, {281} repugnant in every particular to that with France. When war actually broke out between the two, England preferred to throw her weight against France, thereby almost helping Charles to the throne of universal empire and raising up for herself an enemy to menace her safety in many a crisis to come. In the end, then, Wolsey's perfidious policy failed; and his personal ambition for the papacy was also frustrated. But while "the congress of kings," as Erasmus called it, was disporting itself at Guines and Calais, the tide of a new movement was swiftly and steadily rising, no more obeying them than had the ocean obeyed Canute. More in England than in most countries the Reformation was an imported product. Its "dawn came up like thunder" from across the North Sea. Luther's Theses on Indulgences were sent by Erasmus to his English friends Thomas More and John Colet little more than four months after their promulgation. [Sidenote: March 5, 1518] By February, 1519, Froben had exported to England a number of volumes of Luther's works. One of them fell into the hands of Henry VIII or his sister Mary, quondam Queen of France, as is shown by the royal arms stamped on it. Many others were sold by a bookseller at Oxford throughout 1520, in which year a government official in London wrote to his son in the country, [Sidenote: March 3, 1520] "there be heretics here which take Luther's opinions." The universities were both infected at the same time. At Cambridge, especially, a number of young men, many of them later prominent reformers, met at the White Horse Tavern regularly to discuss the new ideas. The tavern was nicknamed "Germany" [Sidenote: 1521] and the young enthusiasts "Germans" in consequence. But surprisingly numerous as are the evidences of the spread of Lutheranism in these early years, naturally it as yet had few prominent adherents. When Erasmus wrote Luther that he had well-wishers {282} [Sidenote: May, 1519] in England, and those of the greatest, he was exaggerating or misinformed. At most he may have been thinking of John Colet, whose death in September, 1519, came before he could take any part in the religious controversy.
