This marble-type stone coat of arms proceeds from the European antiques market. As regards to its origin, we only know that it comes from the Kingdom of the Two Sicilies, namely, the historic territories of Naples and Sicily. It must have belonged to a Royal Heritage or public building from a city or town in the Neapolitan or Sicilian Kingdom. As regards its morphology, as it has a three-pointed chief, it can qualify as a Swiss coat of arms, which used to be very common in the Hispanic Kingdoms during the first two decades of the 16th century. At first sight, we can observe that it belonged to a member of the House of Aragon, a Trastámara from the Neapolitan branch of the Trastámara; but if we analyze the last quarter, we can assure that it belongs to the arms of Ferdinand the Catholic. The coat of arms is divided in quarters that include many arms, not only the lions and castles of Castile and León, the pallets of Aragon and the black eagles of Naples and Sicily, but also the stripes of Hungary, the fleurs-the-lis of the Anjou and the Jerusalem cross, which represents that lost crusader kingdom. In the base we can see the pomegranate enté en point, which represents the kingdom that Ferdinand and Isabelle conquered in 1492, the last Islamic kingdom of Spain, the Kingdom of Granada. That means that the coat of arms is subsequent to that year.
Moreover, the coat of arms reveals that it is also subsequent to the death of Isabella, the Catholic Queen, because the arms related to the political ambitions of Alfonso of Aragon. Ferdinand's uncle, are present. He received the rights over this Kingdom and over the Kingdoms of Hungary and Jerusalem from Joanna II, last Queen of Naples in the Angevin line, which is why the fleurs-the-lis of the Anjou are present. II regretted her adoption, King Alfonso conquered her kingdom, and Sicily already belonged to Aragon in the 13th century.
