The Coat of arms of Bivona is the representational emblem of the Italian town of Bivona, in Agrigento, Sicily, situated in the Monti Sicani mountain range.[1]
It represents the ancient state of nobility and wealth, social and cultural development of the country, that became a duchy in the 16th century,[2] capital of the district,[3] and a Comune, in the 19th century; and the seat of sottintendenza and sub-prefecture,[4] [5] reason that the emblem also act as the coat of arms of the province of Agrigento.
In ancient times the emblem was stamped on the crown walls:[6] in 1554, the town was adorned with the title of city.[2]
The description of the coat of arms, included within the municipal charter of Bivona, is as follows:[7]
Until 1785, a seal engraved with the municipal arms of the lord of that time was used on the official acts of the University of Bivona. On 5 March 1785, with the publication of the royal circular letters, it was willing that the barons of the kingdom do not interfere in the election of judges, and mayors of their respective lands:[8] thus, there was no longer baronial issuing power, the city administration bivonese was endowed with a new seal. The latter bore the emblem of the House of Bourbon-Sicily at the top, and a few naturalistic elements (such as some plants) around a tower at the bottom.
Below are the descriptions of three municipal seals of Bivona of 1593,[9] the 1638 and 1801.[10] [11]
A seal of the University of Bivona in a document of 1593 (currently available at the State Archives of Palermo)[12] probably depicts the arms of families D'Aragona, De Luna d'Aragona and Peralta, although there are doubts about the exact identification of the latter.[9]
In 1593 a woman was the head of the duchy of Bivona, Aloisia de Luna,[13] daughter of Peter de Luna (first Duke of Bivona) and Isabella de Vega, also the daughter of Juan de Vega, Viceroy of Sicily.[14] Aloysia became the investiture of the duchy in September 1592, after the death of brother Giovanni,[15] in 1567 she married Cesare Moncada, died in 1571;[15] in 1577 she became the wife of Antonio Aragon, duke of Montalto.[13]
A seal of the University of Bivona present in a document dated May 17, 1638 (also available at the State Archives of Palermo)[16] depicts the arms of the families of Luna, de La Cerda and Aragona-Sicilia; missing are the arms of the Moncada family.[10]
In 1638, Luigi Guglielmo Moncada was the Duke of Bivona, great-grandson of Aloysia de Luna and descendant of the Aragon family.[17]
