Ali-Shir Nava'i
From childhood onward Attar, encouraged by his father, was interested in the Sufis and their sayings and way of life, and regarded their saints as his spiritual guides. At the age of 78, Attar died a violent death in the massacre which the Mongols inflicted on Nishapur in April 1221. Today, his mausoleum is located in Nishapur. It was built by Ali-Shir Nava'i in the 16th century and later on underwent a total renovation during the rule of Reza Shah in 1940.
