Questions for Viewing
- Look closely at the featured work of art; note its individual pieces and the way they link to one another. How might the various parts move?
- Describe the markings that cover each surface and the forms that make up the screenlike panel that covers the face (the rete, the Latin word for "net"). What might these shapes and markings indicate? (See fig. 19 and The Parts of an Astrolabe.)
- An astrolabe is a tool that performs a range of tasks that include telling time, identifying when the sun will rise and set, and locating celestial objects in the sky. What are some ways this information might be useful every day? In the Islamic world, astrolabes were often used to help find the direction of Mecca (qibla) and determine prayer times. In this example, the rete forms the bismillah, the opening phrase of most chapters of the Qur'an.
- What are some devices people use today to help with telling time, navigating the environment, and viewing distant objects?
Activity Setting: Classroom
Materials: Paper; pencil; research materials supporting investigations of an astrolabe, sundial, celestial globe, compass, water clock, and telescope; a computer and Internet access (ideal but not required)
Subject Area: Science
Duration: Approximately 60 minutes (longer if you plan to build and test models of each device)
Research the origin, function(s), and underlying principles of one of the following tools: astrolabe, sundial, compass, water clock, or telescope. Compare and contrast your findings with your peers. Discuss what functions or guiding principles, if any, the works share and how these devices might support daily life or scientific practice. If time permits, build and test a model of the device (see Resources below for links to relevant materials).
Reflect on the various tools used today to support tasks such as finding your way to a new place, telling time, and observing objects too far away or too small to see with the naked eye. What benefits might these devices offer? What limitations do they present? Why might some people view the creation of a digital watch or GPS navigation as "progress" while others challenge this idea? Watch the video Tom Wujec Demos the 13th-Century Astrolabe. In what ways does his presentation challenge or reinforce your opinion about the benefits or limitations of modern technological devices?
