Egypt had sailed through the Red Sea, and keeping the land on their right had rounded Africa and returned through the Straits of Gibraltar; on the way they had found that the sun appeared for a time on the north side.
A hundred years later, after Egypt had fallen into his hands, Alexander had founded the city of Alexandria on the western side of the delta of the Nile. The city was destined to become the second city of the Roman Empire. Connected by canal with the Red Sea, and making use of the newly understood monsoon winds (A.D. 47) for crossing the Arabian Sea, it became the chief port of the maritime trade with Persia, India, and the regions beyond.
References to this maritime trade exist in the Chinese histories as well as in the writings of the Greeks. In A.D. 97 a Chinese envoy, Kan Ying, travelling from Central Asia reached the shores of the Persian Gulf, and was informed by the seamen whom he met that the sea-route from the Gulf proceeded first south-west and then north-west to the port of Wu-ch'ih-san (Alexandria), the return journey taking three months with favourable winds, and two years with unfavourable winds.
The Chinese records speak of the Persians and the Indians trading by sea with Ta-ts'in (the Chinese name for the Eastern Provinces of the Roman Empire: Egypt, Syria and Asia Minor) and of the fact that the profits were ten-fold.
They speak also of traffic between India and China by sea, and record that in A.D. 120 two jugglers who claimed to have come from the Roman Orient (Ta-ts'in) reached Burma, and were sent by the king of Burma as a present to the Emperor of China, via the Burma Road.
About the same time a book was written by an unknown Greek sailor called The Periplus of the Erythraean Sea giving a port-to-port description of the voyage down the Red Sea and around the Indian Ocean to the Malay Peninsula (The Land of Gold) 'under the very rising of the sun, with a notice of China beyond.
Shortly after this in the 2nd century A.D. the Geography of Ptolemy was written at Alexandria, where Ptolemy gathered together and systematized all that was known to the Western world about Asia and Africa. In particular he plotted the longitude and latitude of the places known, which when transferred to a modern map give surprisingly accurate results, reaching to China itself.
From this time notices of the sea-route increase, both on the Greek and on the Chinese side. The Chinese histories in particular show a rapidly increasing knowledge in the early
