Red Sea in Smiths Bible Dictionary

1. Name. --The sea known to us as the Red Sea was by the Israelites called "the sea," Ex 14:2,9,16,21,28; 15:1,4,8,10,19; Jos 24:6,7 and many other passages, and specially "the sea of Suph." Ex 10:19; 13:18; 15:4,22; 23:31; Nu 14:25 etc. This word signifies a sea-weed resembling wool, and such sea-weed is thrown up abundantly on the shores of the Red Sea; hence Brugsch calls it the sea of reeds or weeds. The color of the water is not red. Ebers says that it is of a lovely blue-green color, and named Red either from its red banks or from the Erythraeans, who were called the red people. 2. Physical description. --In extreme length the Red Sea stretches from the straits of Bab el-Mendeb (or rather Ras Bab el-Mendeb), 18 miles wide. in lat. 12 degrees 40' N., to the modern head of the Gulf of Suez, lat. 30 degrees N., a distance of 1450 miles. Its greatest width may be stated at about 210 miles. At Ras Mohammed, on the north, the Red Sea is split by the granitic peninsula of Sinai into two gulfs; the westernmost, or Gulf of Suez, is now about 150 miles in length, with an average width of about 20, though it contracts to less than 10 miles; the easternmost or Gulf of el-'Akabeh, is about 100 miles long, from the Straits of Tiran to the 'Akabeh, and 15 miles wide. The average depth of the Red Sea is from 2500 to 3500 feet, though in places it is 6000 feet deep. Journeying southward from Suez, on our left is the peninsula of Sinai; on the right is the desert coast of Egypt, of limestone formation like the greater part of the Nile valley in Egypt, the cliff's on the sea margin stretching landward in a great rocky plateau while more inland a chain of volcanic mountains, beginning about lat. 28 degrees 4' and running south, rear their lofty peaks at intervals above the limestone, generally about 15 miles distant. 3. Ancient limits. --The most important change in the Red Sea has been the drying up of its northern extremity, "the tongue of the Egyptian Sea." about the head of the gulf has risen and that near the Mediterranean become depressed. The head of the gulf has consequently retired gradually since the Christian era. Thus the prophecy of Isaiah has been fulfilled, Isa 11:15; 10:5 the tongue of the Red Sea has dried up for a distance of at least 50 miles from its ancient head. An ancient canal conveyed the waters of the Nile to the Red Sea, flowing through the Wadi-t Tumeylat and irrigating with its system of water-channels a large extent of country. It was 62 Roman miles long, 54 feet wide and 7 feet deep. The drying up of the head of the gulf appears to have been one of the chief causes of the neglect and ruin of this canal. The country, for the distance above indicated, is now a desert of gravelly sand, with wide patches about the old sea-bottom, of rank marsh land, now called the "Bitter Lakes." At the northern extremity of this salt waste is a small lake, sometimes called the Lake of Heropolis; the lake is now Birket-et-Timsah "the lake of the crocodile," and is supposed to mark the ancient head of the gulf. The canal that connected this with the Nile was of Pharaonic origin. It was anciently known as the "Fossa Regum" and the "canal of Hero." The time at which the canal was extended, after the drying up of the head of the gulf, to the present head is uncertain, but it must have been late, and probably since the Mohammedan conquest. Traces of the ancient channel throughout its entire length to the vicinity of Bubastis exist at intervals in the present day. The land north of the ancient gulf is a plain of heavy sand, merging into marsh-land near the Mediterranean coast, and extending...
