From D.H. Montgomery's Leading Facts of English History (I'm preparing it for Project Gutenberg, visit to see the draft):

"It was, in fact, a time when the Protestant faith seemed everywhere marked for destruction. In France evil counselors had induced the King to order a massacre of the Reformers, and on St. Bartholomew's Day thousands were slain. The Pope, misinformed in the matter, ordered a solemn thanksgiving for the slaughter, and struck a gold medal to commemorate it. Philip II of Spain, whose cold, impassive face scarcely ever relaxed into a smile, now laughed outright."
