Panagia Naupaktiotissa and the Parchment of Palermo
In the archives of Regia Capella Palatina at Palermo, Sicily, is kept a Byzantine parchment which bears the copy of the foundation act of a religious brotherhood of the 11th century, based in Thebes, Boeotia, and decorated with an illumination depiction of the icon of the Mother of God Naupaktitissa which was kept in the monastery under the same name. The see of the cult of Panagia Naupaktiotissa, as was the common name, was the Metropolitan church of the city and the cult itself was widespread in Mainland Greece in the Late Byzantine period. The specific brotherhood was founded in 1048.
The Metropolitan church (cathedral) received important donations and privileges from the emperors of the Middle and Late Byzantine period, particularly of the Komnenian dynasty; a "chrysoboullon" of Theodoros Angelos Komnenos Doukas (1228) is still extant stating his decision to support the church and exempt it from taxation. The Angevins and the Venetians respected and assimilated the worship of Panagia, which was adopted in Italy as well as Madona di Lepanto, i.e. in the iconographic form depicted on the parchment.
