| Just think of the quipus which enabled the Incas to manage their food administration in the 15th century. |
| These runners carried oral messages, small packages, or quipus from village to village and from the capital to all parts of the empire. |
| Among the most important objects we can mention an great collection of mommies and Paracas mantles, utensils, quipus and musical instruments. |
| The quipus of the ancient Incas of Peru encoded a wide range of data about people, land, and crops for the government bureaucracy. |
| I wonder whether there might be lessons in the Incan calendar and quipus. |
