Ardabil is one of the most noble names in Persian carpets. Two of the largest rugs ever made were in the shrine of Shaykh Safi al-Din, and after an earthquake, were sold to Zeigler & Co. The undamaged one is on display at the Victoria & Albert Museum, lit for only ten minutes every half hour to preserve its colours. The damaged one was in Los Angeles, and was recently restored in London. The English designer William Morris, when sent by the V & A to inspect them, reported them to be of "singular perfection ... logically and consistently beautiful".
