Difficulty: HardNavigation and Cartography

Marshallese navigators produced different types of stick charts, including the rebbelib and the mattang. Which of the following statements accurately describes how the form of a mattang relates to its specific function?

  1. Its symmetrical structure illustrates generalized wave refraction and swell patterns around an abstract island, serving as an instructional tool to train apprentice navigators on land.Answer
  2. B
    Its asymmetrical grid of coconut midribs functions as a literal topographic map, allowing navigators to measure exact nautical distances between specific Marshallese atolls while at sea.
  3. C
    Its curved rods are designed to be aligned with the horizon and the night sky during open-ocean voyaging to track celestial navigation paths in real time.
  4. D
    Its construction from shells and sticks signifies its role as a gendered prestige object woven by women to be exchanged during diplomatic ceremonies rather than a cartographic device.

Answer

The symmetrical structure of a mattang illustrates generalized wave refraction and swell patterns around an abstract island, serving as an instructional tool to train apprentice navigators on land.
The correct answer accurately reflects that the mattang is a symmetrical stick chart used for training purposes to illustrate general wave patterns, such as refraction and reflection, around an abstract island. It was studied on land rather than carried on board.

Step-by-Step Solution

1
Analyze the question stem to identify the distinction between different types of Marshallese stick charts, specifically the mattang.
The mattang is characterized by its symmetrical form, unlike the geographically specific meddo or rebbelib charts.
Recognizing the formal traits of the mattang helps isolate its functional role.
2
Evaluate the functional context of stick charts in Marshallese society.
Stick charts were used on land for memorization and training, never carried aboard vessels.
Understanding the land-based pedagogical context rules out distractors suggesting active on-board use.
3
Select the option that correctly describes the symmetrical design and educational/training purpose of the mattang.
The statement about symmetrical structure representing generalized swell patterns for instruction on land matches the art-historical consensus.
The correct answer must connect the symmetrical design to its function as a training device.

Key Concept

Function and formal characteristics of Marshallese navigation stick charts, distinguishing training aids (mattang) from geographic maps (rebbelib).
