In his notes to St. Augustine, 1610, Ludovicus Vives writes about a lamp that was found in his father's time, in 1580 A.D. According to the inscription, the lamp was burning for 1,500 years, however when it was touched it fell into pieces. Obviously, Ludovicus Vives did not share St. Augustine's views as he considered perpetual lamps to be an invention of very skilled men and not demons.
