On other web sites you can read about Mevlana. His sarcophagus is in the Mevlana Museum, which is both a place of pilgrimage for many muslims as well as people of other creeds who are attracted by his teaching, and a museum, housing some very good pieces of glassware, copperware, carpets, caligraphy et cetera. In a number of rooms scenes from the daily life in the dervish world are recreated.
This is a small part of a huge "April"bowl, used to collect the first rainwater of the season that would then be used to tip Mevlana's turban in it, offered to the sick as a remedy.
