Giovanni de' Medici - 25 + 1 = 26. Do not underestimate his powers. In a recently constructed Commercial Hub, Giovanni spares you a great deal of production at a moment of the game at which Banks are somewhat costly; the ten to fifteen gold gained from the Hub's adjacency bonus, a Market, and a Bank is also a useful bonus, as are the three Great Merchant points that collectively ensue from them. The vacant slots for Great Works renders it extremely useful for Cultural Victories, making Giovanni one of the game's more versatile Great People.
