On 6 January 1378 King Charles V of France took his place in the centre of the top table at a banquet given in honour of a distinguished guest, his uncle the Emperor Charles IV. The setting in the Palais de la Cité, the company and the menu were appropriately sumptuous. Resplendent hangings covered the wall behind the marble table: the noblest guests sat at five large tables, each raised on its own platform; and divided from them by barriers were other tables with seats for more than 800 knights. The entire company was treated to three elaborate courses, each of ten dishes. Then, from its previous place of concealment at the end of the hall, a massive model of a ship emerged carrying a crowd of armed warriors, among them persons identifiable by their arms as Godfrey of Bouillon and other leaders of the First Crusade, together with Peter the Hermit, looking—we are told—as much like the descriptions of him in the chronicles as possible. Propelled smoothly along the floor by men concealed within, it crossed in front of the top table and was then turned round to face towards the centre. An even more massive structure was next brought forward—this time representing the city of Jerusalem, complete with battlemented walls and towers defended by men dressed as Saracen warriors, with the Temple high in the middle and rising still higher above it a tower on which was another figure in Saracen dress ‘crying the Law’ in Arabic. The Crusaders then descended from the ship and attacked the city with scaling ladders, from which some were made to fall off, until finally the knights entered the city, tossed the unfortunate defenders over the walls and raised in triumph the banners they had brought with them: after which the dinner finished.
