Age of Exploration S2

Explain how early maps from the 1300s were created and what limitations they had. (DoK Level 3)

• They were synthesized from fragmented narratives provided by itinerant merchants, religious pilgrims, and classical manuscripts, often resulting in cartographic depictions characterized by conjectural coastlines, mythological elements, and significant distortions due to the absence of empirical surveying techniques or uniform cartographic conventions.

• They were generated through advanced trigonometric calculations and systematic aerial observations, yielding cartographic representations with minimal spatial inaccuracies and comprehensive topographical detail.

• They were meticulously assembled by state-sponsored cartographers utilizing a network of standardized geodetic measurements and exhaustive terrestrial reconnaissance, ensuring high fidelity to actual geographic features.

• They were faithful facsimiles of ancient cartographic archives from lost civilizations, meticulously preserved and transmitted without alteration, thereby maintaining an unbroken lineage of geographic precision.

What challenges did explorers face when using early map designs to chart new worlds?

• They contended with profound navigational inaccuracies and systemic miscalculations stemming from rudimentary cartographic methodologies, limited astronomical instrumentation, and fragmented or speculative geographic data.

• They grappled with complex logistical dilemmas, including the absence of advanced preservation technologies for perishable supplies and the unpredictable duration of transoceanic expeditions.

• They encountered significant difficulties in decoding indigenous spatial representations and topographical cues, exacerbated by deep-seated cultural divergences and the lack of standardized translational frameworks.

• They were impeded by intricate geopolitical constraints, such as clandestine restrictions on the dissemination or production of cartographic intelligence enforced by competing imperial powers or regulatory authorities.

Describe the progression of map-making from the 1300s to modern times and the impact it had on exploration. (DoK Level 3)

• Cartography transitioned from medieval, symbolic, and often Eurocentric representations to empirically grounded, mathematically informed, and globally comprehensive maps. This evolution not only enabled more precise navigation and the discovery of new territories, but also accelerated the development of global trade networks, imperial expansion, and the exchange of scientific and cultural knowledge.

• Despite advancements in navigational instruments, the proliferation of increasingly sophisticated maps paradoxically led some explorers to question their reliability, resulting in a complex interplay between traditional wayfinding methods and emerging cartographic science.

• While early maps were sometimes imbued with religious or mythological symbolism, their gradual transformation into practical tools for navigation and territorial claims reflected broader shifts in scientific thought and geopolitical ambitions.

• Although the fundamental purpose of maps—to represent spatial relationships—remained constant, the methodologies, accuracy, and intended audiences of cartographic works underwent significant transformation, challenging explorers to continually adapt their strategies and interpretations.

Explain two detailed reasons why people in the Middle Ages needed spices.

• To stimulate the growth of transcontinental commerce and to serve as decorative elements during elaborate banquets.

• To slow the proliferation of microorganisms in food preservation and to disguise the taste of food that had deteriorated due to limited storage methods.

• To engineer protective dwellings and to manufacture woven materials for garments.

• To synthesize complex medicinal compounds and as a pigment base for illuminated manuscripts.

Match the spice to the correct part of the plant: Which spice comes from the bark of a tree?

• Nutmeg

• Cassia

• Cinnamon

• Sassafras

Which spice is the strong-smelling center of a nut and is found in the East Indian Islands?

• Grated nutmeg

• Nutmeg seed

• Javitri (mace)

• Myristica fragrans aril

What was the main purpose of the magnetic compass for sailors in the 15th century?

• To analyze oceanic thermohaline circulation patterns

• To ascertain orientation relative to Earth's magnetic poles and facilitate transoceanic navigation

• To predict atmospheric pressure fluctuations during maritime expeditions

• To enable encrypted communication between geographically separated fleets

Which instrument did sailors use to measure their latitude, and why was this important for navigation?

• The astrolabe, as it enabled mariners to determine their latitude by measuring the altitude of celestial bodies above the horizon, a crucial factor for open-ocean navigation before the advent of accurate timekeeping devices.

• The sextant, as it allowed navigators to ascertain their longitude by calculating the angular distance between the moon and a given star, a method requiring complex astronomical tables and precise timing.

• The marine chronometer, as it provided the exact time at a reference location, which, when combined with local noon observations, allowed for the calculation of longitude rather than latitude.

• The barometer, as it measured atmospheric pressure changes to predict weather patterns, which could indirectly influence navigational decisions but did not provide positional information.

What were the three things sailors needed to know to measure longitude at sea before the late 18th century?

• The precise time at a reference meridian, the ship’s course relative to geographic north, and the vessel’s speed determined by dead reckoning

• The barometric pressure at sea level, the vessel’s gross register tonnage, and the navigator’s proficiency in celestial navigation

• The solar declination at local noon, the total complement of officers, and the hull’s color pattern

• The distance from the nearest landmass, the nature of cargo manifest, and the national flag displayed by the vessel

How did Portuguese sea captains contribute to the exploration of Africa’s west coast in the 15th century?

• By establishing a network of heavily fortified feitorias and instituting complex administrative hierarchies to control maritime commerce along the coastline

• By systematically compiling detailed portolan charts, maintaining exhaustive maritime logs, and erecting intricately inscribed stone markers known as padraos to demarcate territorial claims at key landing sites

• By designing hybridized caravel models integrating lateen and square sails, and inventing sophisticated navigational instruments such as the mariner’s astrolabe and cross-staff

• By conducting exclusive trade negotiations with coastal polities while deliberately eschewing any inland reconnaissance or territorial expansion
