Pergamon
Pergamon lies on the north edge of the Caicus plain in the historic region of Mysia in the northwest of Turkey. The Caicus river breaks through the surrounding mountains and hills at this point and flows in a wide arc to the southwest. At the foot of the mountain range to the north, between the rivers Selinus and Cetius, there is the massif of Pergamon which rises 335 metres above sea level. The site is only 26 km from the sea, but the Caicus plain is not open to the sea, since the way is blocked by the Karadağ massif. As a result, the area has a strongly inland character. In Hellenistic times, the town of Elaia at the mouth of the Caicus served as the port of Pergamon. The climate is Mediterranean with a dry period from May to August, as is common along the west coast of Asia Minor.
Pergamon Altar
Between 1431 and 1444 the Italian humanist Cyriacus of Ancona visited Pergamon and described it in his commentarii (diary). In 1625 William Petty, chaplain to Thomas Howard, 21st Earl of Arundel, a collector and art patron, traveled through Turkey, visited Pergamon, and brought back to England two relief panels from the altar. These pieces were forgotten after the Earl's collection was dispersed and were only rediscovered in the 1960s. For this reason these two panels are lacking in the Berlin reconstruction. Other travelers known to have visited Pergamon during the late 18th and early 19th centuries were, for example, the French diplomat and classical scholar Comte de Choiseul-Gouffier, the English architect Charles Robert Cockerell and two Germans, the archaeologist Otto Magnus von Stackelberg and the classical scholar Otto Friedrich von Richter. Choiseul-Gouffier was the first to propose excavations in Pergamon; the other three travelers made drawings of the city's acropolis.
