.,. Poggio would have dismounted and walked up the tree-lined avenue toward the abbey's single, heavy gate.... The granaries at this point in the winter would still have been reasonably full, and there would have would have been ample straw and oats for the horses and donkeys in the stable. Looking around, Poggio would have taken in the chicken coops, the covered yard for sheep, the cowshed with its smell, and the large pigsties. He might have felt a pang for the olives and the wine of Tuscany, but he knew that he would not go hungry....I think I understand the excitement that a scholar would find--as Petrarch, Poggio, and Erasmus did--in searching out forgotten works of antiquity, and I can understand an author wishing to convey that excitement to readers who have not considered it. But above a certain density of "would have"s and "might have"s, one starts to resist.
In 1417, if Fulda was indeed Poggio's destination, that ruler was Johann von Merlau. After greeting him humbly, explaining something about himself, and presenting a letter of recommendation from a well-known cardinal, Poggio would almost certainly have begun by expressing his interest in glimpsing the precious relics of St. Boniface and saying a prayer in their holy presence.
