While both the Norse seafarers of the North Atlantic and the Polynesian navigators of the Pacific successfully traversed vast open oceans without modern instruments, their methodologies relied on fundamentally different environmental interactions. Norse navigation was primarily episodic and dependent on transient celestial and physical markers. To navigate the foggy, storm-prone northern seas, Norse sailors utilized the 'sunstone'—a polarizing crystal of Iceland spar that could locate the sun even through heavy overcast—and closely observed the migratory patterns of birds and whales to estimate proximity to land. In contrast, Polynesian wayfinding was a continuous, holistic discipline centered on the 'star path' (aveia). Rather than relying on physical tools to isolate specific environmental phenomena, Polynesian navigators memorized complex stellar paths, aligning their vessels with the rising and setting points of key stars. Furthermore, while the Norse viewed ocean swells primarily as hazardous obstacles to be negotiated, Polynesian navigators interpreted swells as reliable, permanent roadmaps. They could detect the refractive patterns of waves bouncing off distant islands, allowing them to navigate in total darkness without the need for optical aids like the sunstone.
According to the passage, how did the Norse use of the sunstone differ from the Polynesian use of the star path?
- AThe sunstone served as a permanent roadmap for navigating in total darkness, while the star path was an episodic guide reserved for heavy overcast.
- BThe sunstone was designed to trace the migrations of birds and whales, while the star path was used to track the refractive patterns of waves.
- The sunstone was a physical tool employed to detect a specific environmental cue, while the star path depended on memorized celestial trajectories.Cevap
- DThe sunstone was a continuous method of navigation across open oceans, while the star path was an episodic system relying on transient markers.
