Abraham, servant of God, of K'ot'ay [Kütahya]. In this year 959 [AD 1510]". In 1905–1907, during the construction of a new post office in the Sirkeci district of Istanbul near the shore of the Golden Horn, pottery fragments were unearthed that were decorated with spiral designs on a white background. As a result, pottery with similar spiral patterns became known as 'Golden Horn ware'. It was not until the 1930s that art historians fully realised that the different styles of pottery were probably all produced in Iznik. In 1957 Arthur Lane, keeper of ceramics at the Victoria and Albert Museum, published an influential article in which he reviewed the history of pottery production in the region and proposed a series of dates. He suggested that 'Abraham of Kütahya' ware was produced from 1490 until around 1525, 'Damascus' and 'Golden Horn ware' were produced from 1525 until 1555 and 'Rhodian' ware from around 1555 until the demise of the Iznik pottery industry at the beginning of the 18th century. This chronology has been generally accepted. İznik and Kütahya The 'Abraham of Kutahia' ewer of 1510 is not the only vessel with a possible Kütahya origin. A damaged water bottle decorated in the 'Golden Horn' style has two underglaze inscriptions in Armenian script; one, dated 1529, refers to the commissioner of the vessel, Bishop Ter Martiros, the other refers to the vessel as being sent as "an object of K'ot'ays" for a monastery. Lane argued that it was unlikely that either the 'Abraham of Kutahia' ewer or the water bottle had been made in Kütahya. However, subsequent archaeological excavations in Kütahya have unearthed fragments of pots in the blue and white Iznik style that had been damaged during manufacture ('wasters') providing evidence that fritware pottery was produced in the town. The designs, materials and manufacturing technique appear to have been similar to that used in İznik. Kütahya is further from Istanbul with less easy access to the capital and was probably only a small pottery producing centre in the 16th century. Nevertheless, it is likely that some of the pottery that is currently labelled as 'Iznik' was manufactured in Kütahya. The art historian Julian Raby has written: "For the moment we have no choice but to call all Ottoman glazed pottery of the 16th and 17th centuries by the generic label 'Iznik', and to hope that in time we can learn to
