In this century, under sultan Barsbay Bulaq became the main port of Cairo. Bulaq is a dense indigenous district filled with small-scale workshops of industries such as the old printing press , metalworking and machine shops, which supported

The Periplus also describes how Hippalus first discovered the direct route from the Red Sea to India . The Red Sea was favored for Roman trade with India starting with the reign of Augustus , when the Roman Empire gained control over the Mediterranean, Egypt , and

His son and successor, Shamsuddin Ahmad Shah , had slightly delayed the dispatching but nevertheless sending the initial gifts of his father off whilst also adding more gifts of his own. In total, the package was worth over 12,000 red tankas and included clothes, cotton, ginger , myrobalan and other spices. The envoy, travelling from Bengal to Cairo via

As well as Mare Rubrum in Latin (alternatively Sinus Arabicus , literally "Arabian Gulf"), the Romans called it Pontus Herculis (Sea of Hercules). Other designations include the Arabic : البحر الأحمر , romanized : Al-Baḥr Al-Aḥmar (alternatively بحر القلزم Baḥr Al-Qulzum , literally "the Sea of Clysma "),

To its north lie the Sinai Peninsula , the Gulf of Aqaba , and the Gulf of Suez —leading to the Suez Canal . It is underlain by the Red Sea Rift , which is part of the Great Rift Valley . The Red Sea has a surface area of roughly 438,000 km (169,000 sq mi),

It has an average depth of 490 m (1,610 ft), and in the central Suakin Trough it reaches its maximum depth of 3,040 m (9,970 ft). Approximately 40% of the Red Sea is quite shallow at less than 100 m (330 ft) deep, and about 25% is less than 50 m (160 ft) deep. The extensive shallow shelves are noted for their marine life and corals . More than 1,000 invertebrate species and 200 types of soft and hard coral live in

In 1949, a deep water survey reported anomalously hot brines in the central portion of the Red Sea. Later work in the 1960s confirmed the presence of hot, 60 °C (140 °F), saline brines and associated metalliferous muds. The hot solutions were emanating from an active subseafloor rift .

By observing the strontium isotope composition of the Red Sea brines, it is possible to deduce how these salt waters found at the bottom of the Red Sea could have evolved in a similar way to Lake Asal, which ideally represents their compositional extreme. The high salinity of the waters was not hospitable to living organisms. Sometime during

In 1436, the Governor of Jeddah sent some men to search the Red Sea for the gifts and they came back with the textiles although the spices were damaged by the water. After Barsbay was informed of this by the governor, he ordered for the arrest of all members of the Bengali embassy, the confiscation of their envoy's merchandise, and banned them from ever travelling to Cairo again. The revenues from this military victory and these trade policies may have helped him finance his construction projects, and he

The resulting change in biodiversity, without precedent in human memory, is currently accelerating, in particular for fishes according to surveys engaged by the Mediterranean Science Commission . The rich diversity of the Red Sea is in part due to the 2,000 km (1,240 mi) of coral reef extending along its coastline; these fringing reefs are 5000–7000 years old and are largely formed of stony acropora and porites corals. The reefs form platforms and sometimes lagoons along

In the process he diverted the Indian Ocean trade routes through Jeddah (closer to Cairo) and also introduced a state monopoly on sugar and pepper. His Red Sea activity included the final destruction in 1426 of ‘Aydhab , a once important port which had been in decline in the previous century. The 15th century saw an international economic recession. During this time, Barsbay knew

This canal was a predecessor to the modern Suez Canal , which
