Coat of arms of Puerto Rico.  Flanked by crowned "F" and "Y" letters for Ferdinand and Isabella of Spain.  The central emblem is the Agnus Dei (symbolic representation of Christ as a lamb) sitting on a book sealed with the seven seals of the Book of Revelations in the Bible. Around the edge of the shield are symbols of the kingdoms of Leon and Castile, of the union of Leon and Castile, and of the crusader kingdom of Jerusalem.  The motto is Latin for "John is his name", from the description of John the Baptist's birth in the New Testament.
