Perilʹlo Swords
.Perillo is a “little stone,” a mark by which Julian del Rey, a famous armourer of Toleʹdo and Zaragoza, authenticated the swords of his manufacture. All perillo swords were made of the steel produced from the mines of Mondragon. The swords given by Katharine of Aragon to Henry VIII. on his wedding-day were all Perillo blades.
