Medieval pilgrim badges

Pilgrim badges are decorations worn by some of those who undertake a Christian pilgrimage to a place considered holy by the Church. They became very popular among Catholics in the later medieval period. Typically made of lead alloy, they were sold as souvenirs at sites of Christian pilgrimage and bear imagery relating to the saint venerated there. The production of pilgrim badges flourished in the Middle Ages in Europe, particularly in the 14th and 15th centuries, but declined after the Protestant Reformation of the mid-16th century. Tens of thousands have been found since the mid-19th century, predominantly in rivers. Together they form the largest corpus of medieval art objects to survive to us today... 

Pilgrim badges were cheaply mass-produced in bronze, cuttle-bone or limestone moulds or, less frequently, by die-stamping. Their easy reproducibility and modest media meant that everyone could afford them. British pilgrim badges often have an integral pin and clasp on the reverse whereas continental European badges more usually have sewing loops, but this is not a hard and fast rule. Pilgrims wore badges on their outer clothing and hats or around the neck to show where they had been on pilgrimage...

Badges were made in the Middle Ages for purposes beyond pilgrim souvenirs; livery badges were presented to employees and allies by great figures, and became highly controversial in the decades leading to the Wars of the Roses. Some political badges have survived, including a fine one for the Black Prince. Other badges, with motifs such as lovers' tokens and mini brooches, were perhaps a form of cheap jewelry. Erotic badges showing winged phalluses or vulvas dressed as pilgrims are prolific, although their cultural significance is still debated.

The embedded image shows a pilgrim badge comprised of three phalluses carrying a crowned vulva in a procession [1375-1450].  Found in Brugge.
