individuals. Since this group was too large for efficient administration, a Council of Ten (also called the Ducal Council, or the Signoria), controlled much of the administration of the city. One member of the great council was elected "doge", or duke, to be the chief executive; he would usually hold the title until his death, although several Doges were forced, by pressure from their oligarchical peers, to resign and retire into monastic seclusion, when they were felt to have been discredited by political failure. The Venetian governmental structure was similar in some ways to the republican system of ancient Rome, with an elected chief executive (the doge), a senator-like assembly of nobles, and the general citizenry with limited political power, who originally had the power to grant or withhold their approval of each newly elected doge. Church and various private property was tied to military service, although there was no knight tenure within the city itself. The Cavalieri di San Marco was the only order of chivalry ever instituted in Venice, and no citizen could accept or join a foreign order without the government's consent. Venice remained a republic throughout its independent period, and politics and the military were kept separate, except when on occasion the Doge personally headed the military. War was regarded as a continuation of commerce by other means. Therefore, the city's early employment of large numbers of mercenaries for service elsewhere, and later its reliance on foreign mercenaries when the ruling class was preoccupied with commerce. Although the people of Venice generally remained orthodox Roman Catholics, the state of Venice was notable for its freedom from religious fanaticism, and executed nobody for religious heresy during the Counter-Reformation. This apparent lack of zeal contributed to Venice's frequent conflicts with the papacy. In this context, the writings of the Anglican divine William Bedell are particularly illuminating. Venice was threatened with the interdict on a number of occasions and twice suffered its imposition. The second, most noted, occasion was in 1606, by order of Pope Paul V. The newly invented German printing press spread rapidly throughout Europe in the 15th century, and Venice was quick to adopt it. By 1482, Venice was the printing capital of the world; the leading printer was Aldus Manutius, who invented paperback books that could be carried in a saddlebag. His Aldine Editions included translations of nearly all the known Greek manuscripts of the
