"One spot on the margin of Lake Regillus was for many ages regarded with superstitious awe. A mark, resembling in shape a horse's hoof, was discernible in the volcanic rock; and this mark was believed to have been made by one of the celestial chargers."—Macaulay, Preface to the Battle of the Lake Regillus.
