Within the Persian Rug is a magnificent array of color and design weaved and knotted magically into a cohesive structure of Persian thought, stories, tradition and beliefs. Ancient motifs originating from cave paintings have transferred from the golden age of pottery through basket weaving and to its expression in carpet weaving. To trace the history of the Persian carpet is to follow a path of cultural growth of one of the greatest civilizations the world has ever known. From being simply articles of need, as pure and simple floor entrance covering to protect the nomadic tribesmen from the cold and damp, the increasing beauty of the carpets found them new owners - kings and nobleman, those who looked for signs of wealth or adornment for fine buildings. The first documented evidence on the existence of carpets came from Chinese texts dating back to the Sassanid Dynasty (AD 224 - 641). In AD 628, the Emperor Heraclius brought back a variety of carpets from the conquest of Ctesiphon, the Sassanid`s capital. The most important time in the history of Persian carpets came with the accession to power of the Safavid dynasty (1501 - 1722). During the reign of Shah Abbas (1588 - 1629), commerce and crafts prospered in Persia. Shah Abbas encouraged contacts and trade with Europe and transformed his new capital Esfahan, into one of the most glorious cities of Persia. He also created a court workshop for carpets where skilled designers and craftsmen set to work to create splendid specimens. Most of these carpets were made of silk, with gold and silver threads adding even more embellishment.
