From your classmate, Mary Ann Wark, a call to check out this article:

After Mary Ann’s checkout tour, a conversation with one of her guests on the “Vices” pictured in the Ship of Virtues tapestry resulted in some further discussion and research. The one pictured on the lower right may be an example of anti-Semitic medieval iconography to represent a Jew (pointed head, scraggly beard, and beast shape, with tail). Mary Ann is exploring further research on the topic and will keep all updated.
