The weavers of the Koum Kapi rugs in Istanbul drew on classical 16th century carpets from Safavid Persia and occasionally from Mughal India, notably those that had ended up in the Topkapi Saray Palace. The design of this, the most frequently encountered design from Koum Kapi workshops, is a case in point, deriving directly from the Topkapi Prayer Rugs, (Rogers, J.M. & Tezcan, H., Topkapi Carpets, London, 1987). As our knowledge of the weavers from the beginning of the 20th century continues to develop, the attribution of the master weaver Zareh Penyamin remains highly important. His exacting standards, constant supervision, at all stages of weaving, and innovative techniques visibly set him apart from his contemporaries.
