This city which cannot be expunged from the mind is like an armature, a honeycomb in whose cells each of us can place the things he wants to remember: names of famous men, virtues, numbers, vegetable and mineral classifications, dates of battles, constellations, parts of speech. Between each idea and each point of the itinerary an affinity or a contrast can be established, serving as an immediate aid to memory. So the world’s most learned men are those who have memorized Zora.
