Cairo, EGYPT - The Nile - Faluccas:  Cairo (Arabic: القاهرة‎) is the capital of Egypt and the largest city in the Arab world. Its metropolitan area, with a population of over 20 million, is the largest in Africa, the Arab world, and the Middle East, and the 6th-largest in the world. Cairo is associated with ancient Egypt, as the famous Giza pyramid complex and the ancient city of Memphis are located in its geographical area. Located near the Nile Delta,  Cairo was founded in 969 AD by the Fatimid dynasty, but the land composing the present-day city was the site of ancient national capitals whose remnants remain visible in parts of Old Cairo.  The Nile Delta (Arabic: دلتا النيل‎ Delta an-Nīl or simply الدلتا ad-Delta) is the delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea.  It is one of the world's largest river deltas—from Alexandria in the west to Port Said in the east, it covers 240 km (150 mi) of Mediterranean coastline and is a rich agricultural region.  From north to south the delta is approximately 160 km (99 mi) in length. The Delta begins slightly down-river from Cairo.   A felucca (Arabic: فلوكة‎, possibly originally from Greek ἐφόλκιον (Epholkion)) is a traditional wooden sailing boat used in protected waters of the Red Sea and eastern Mediterranean, in Egypt and Sudan (particularly along the Nile), including Malta and Tunisia, and also in Iraq. Its rig consists of one or two lateen sails.  They are usually able to board ten passengers and the crew consists of two or three people.  This Linen Era (1930-45) postcard is in good condition.
