Great Seal of the Commonwealth of Puerto Rico. Includes crowned "F" and "I" letters for Ferdinand and Isabella of Spain flanking the Agnus Dei (symbolic representation of Christ as a lamb) sitting on a book. Around the edge of the shield are the lions of Leon, the castle of Castile, and the heraldic banner of the Catholic Monarchs. The motto is Latin for "John is his name", from the description of John the Baptist's birth in the New Testament.
