ヤコブス・デ・ウォラギネ
Through Genoese participation in the Crusades, colonies were established in the Middle East, Northern Africa and across the Mediterranean. Genoese Crusaders brought home a green glass goblet from the Levant, which the Genoese have long regarded as the Holy Grail. In his "Golden Legend", the Archbishop of Genoa, Jacobus de Voragine relates the history of the Holy Grail. The Holy Chalice is now kept in the Genoa Cathedral.
