the sixth century, when Narses besieged it for several months in 553. From 576 to 797, under the Lombards, it was the capital of a duchy, known as Ducato di Tuscia, which included a large part of today's Tuscany and the province of Viterbo, during this time the city also minted its own coins. The Holy Face of Lucca (or Volto Santo), a major relic supposedly carved by Nicodemus, arrived in 742. Among the population that inhabited Lucca in the medieval era, there was also a significant presence of Jews. The first mention of their presence in the city is from a document from the year 859. The jewish community was led by the Kalonymos family (which later became a major component of proto-Ashkenazic Jewry). Thanks above all to the Holy Face and to the relics of important saints, such as San Regolo and Saint Fridianus, the city was one of the main destinations of the Via Francigena, the major pilgrimage route to Rome from the north. The Lucca cloth was a silk fabric that was woven with gold or silver threads. It was a popular type of textile in Lucca throughout the mediaeval period. Lucca became prosperous through the silk trade that began in the eleventh century, and came to rival the silks of Byzantium. During the tenth–eleventh centuries Lucca was the capital of the feudal margraviate of Tuscany, more or less independent but owing nominal allegiance to the Holy Roman Emperor. In 1057 Anselm of Baggio (later Pope Alexander II) was appointed bishop of Lucca, a position he held also during the papacy. As bishop of Lucca he managed to rebuild the patrimony of the Church of Lucca, recovering alienated assets, obtaining numerous donations thanks to his prestige, and had the Cathedral of the city rebuilt. From 1073 to 1086, the bishop of Lucca was his nephew Anselm II, a prominent figure in the Investiture Controversy. During the High Middle Ages, one of the most illustrious dynasties of Lucca was the noble Allucingoli family, who managed to forge strong ties with the Church. Among the family members were Ubaldo Allucingoli, who was elected to the Papacy as Pope Lucius III in 1181, and the Cardinals Gerardo Allucingoli and Uberto Allucingoli.
