1. Math and Memory of the Inca

3.  Sophisticated information recording system based on math and mnemonics.  Data stored in a series of knotted cords.  Requires schooling and a bureaucratic class of “accountants” knowledgeable of the specific quipu and system employed.  Also trained in mathematics.

5. Quipu shown in use From the letter of Guzman Pome de Ayala, 1615

8.  Length  Thickness  Color  Material  Position  Add-ons (knots/loops)  Types of knots

9.  Numbers…quantities  Dates  Types of tribute  Town or village names  Commodities  Population figures  Any quantifiable statistic

10.  Our first step is to recognize elements of the quipu.  Next we will try to decode the Inca counting system.  Finally we will put our new knowledge to the test by constructing a quipu of the same type to record a significant number.
