Each of these four objects represents a shift in world history. The Gutenberg Bible, created by Johannes Gutenberg’s movable type printing press in 1454, was the first mass-produced book in Europe. Bronze cannon transformed warfare in Eurasia while the mariner’s astrolabe allowed 15^th century European sailors to determine their latitude and paved the way for Portuguese voyages to India and Brazil as well as more precise cartography. The world map created by Nicolas Desliens highlights those new mapmaking skills in Europe and the region’s growing awareness of the world.
