According to some of the pious writers of antiquity, they made large fires, which might be seen at a great distance, upon the vigil of this saint [John], in token that he was said in holy writ to be "a shining light." Others, agreeing with this, add also, these fires were made to drive away the dragons and evil spirits hovering in the air; and one of them gravely says, in some countries they burned bones, which was called a bone-fire; for "the dragons hattyd nothyng mor than the styncke of brenyng bonys." This, says another, , they have from the heathens. The author last cited laments the abuses committed upon thes occasions. "this vigil," says he, "ought to be held with cheerfulness and piety, but not with such merriment as is shewn by the profane lovers of this world, who make great fires in the streets, and indulge themselves with filthy and unlawful games, to which they add glotony and drunkenness, and the commission of many other shameful indecencies."
