Chalcedon
The site of Chalcedon is located on a small peninsula on the north coast of the Sea of Marmara, near the mouth of the Bosphorus. A stream, called the Chalcis or Chalcedon in antiquity and now known as the Kurbağalıdere (Turkish: "stream with frogs"), flows into Fenerbahçe bay. There Greek colonists from Megara in Attica founded the settlement of Chalcedon in 685 BC, some seventeen years before Byzantium.
Ur of the Chaldees
Ur Kaśdim ( "ʾur kasdim"), commonly translated as Ur of the Chaldees, is a city mentioned in the Hebrew Bible as the birthplace of the Israelite and Ismaelite patriarch Abraham. In 1862, Henry Rawlinson identified Ur Kaśdim with Tell el-Muqayyar, near Nasiriyah in southern Iraq. In 1927, Leonard Woolley excavated the site and identified it as a Sumerian archaeological site where the Chaldeans were to settle around the 9th century BCE. Recent archaeology work has continued to focus on the location in Nasiriyah, where the ancient Ziggurat of Ur is located.
