"A sack," Baudolino explained, like a man who knows a trade well, "is like a grape harvest: you have to divide the tasks. There are those who press the grapes, those who carry off the must in the tuns, those who cook for others, others who go to fetch the good wine from last year.... a sack is a serious job,"
