This document provides an overview of the tapestry "Tapestry of the Thousand Longest Rivers in the World" created by Alighiero Boetti from 1976-1982. The tapestry depicts a map of the world showing the locations of the thousand longest rivers. It is a complex work that required extensive research to identify all the relevant rivers and plot their paths across multiple panels that were later joined together. The tapestry reflects Boetti's interest in geography and world maps through an unconventional artistic medium.
