English: An incomplete lead alloy Medieval pilgrim badge probably dating from the 15th century, probably depicting St. Thomas. The badge has a semi-circular base with is cross hatched and has a border of pellets in rings along the top. A strip of metal projects from the centre of the crescent and may represent a standing figure. It divides near the top with a downward curving spur on each side. These are incomplete. Further projections from the base suggest that the badge was openwork and may have originally been circular or anchor shaped. The breaks are well patinated. On the reverse is a vertical rib which strengthens the possible standing figure.The metal has a cream coloured patina. It is not clear what the badge represents. The semi-circular element could be interpreted as a ship, or a basket, or perhaps a nest (for a Pelican in her Piety badge?).

Some ship shaped pilgrim badges are linked with Thomas Becket returning from exile, and are know to have been produced at Canterbury. This example does not match any of the designs illustrated in Spencer (1998), but may reflect the same scene.

A common design of pilgrim badge found in London depicts the Virgin and Child in a crescent moon. This design has been tentatively associated with Our Lady of Willesden. Very many varieties of this design our known, but none in Spencer match this example as they are all more crescent shaped than this one.

St Ursula is also depicted on pilgrim badges in a ship and 15th century badges are known which depict her and her ship on the base of a circular badge of Cologne, mainly known for the cult of the Three Kings. Badge 257e on page 262 of Spencer has the most similarities to this example. Another (but very different) St Ursula souvenir on the database is LANCUM-61F133.

Michael Lewis and Naomi Speakman of the British Museum have compared the badge to the examples in the British Museum collection, but have not found a match. They feel that it is most likely to be St Thomas who is depicted.
