This type of carpet is known as a ‘Polonaise carpet’ even though it was made in Iran. The design of this fragment is nearly identical to that of a huge carpet donated to the shrine at Najaf in Iraq, probably by Shah Abbas the Great.
The misleading name arose because carpets of this type came to Europe in the early 17th century through trade or as royal gifts. Many were found in Poland and were later mistaken for Polish products. This gave rise to the term ‘Polonaise carpet’.
