LUBLIN, POLAND—A metal detectorist in southeast Poland discovered a medieval pilgrim badge, which was made of tin-lead alloy and decorated with a mythological design, according to a Live Science report. Such badges were often worn by Christian pilgrims to signify that they were traveling or had traveled to a certain holy place, and were also believed to safeguard the wearer against illness and accidents while on a journey. At the center of this circular badge is the figure of a basilisk, a winged mythological creature that resembles a dragon. Although researchers have found other pilgrim badges throughout Poland, this is the first to feature the image of a basilisk. More commonly, the medieval artifacts depict saints or knights, or are shaped like shields, crosses, or spirals.
