The earliest writing of Europeans on the East refer to these fisheries. An account of them was given by the Greek writer Megasthenes, who accompanied Seleucus Nicator, the Macedonian general, in his Asiatic conquests, about 307 B.C. Shortly afterward they were noted by the Greek historian, Isidorus of Charace, in his account of the Parthian Empire. Extracts from Nearchus preserved by Arrian also mention them. Ptolemy speaks of the pearl fisheries which existed from time immemorial at Tylos, the Roman name for the present Island of Bahrein. These resources were well known in the days of Pliny. In his “Historia Naturalis,” Book IX, ch. 35, he says: “But the most perfect and exquisite [pearls] of all others be they that are gotten about Arabia, within the Persian Gulf.”[90] Pliny states also (Book VI, ch. 25) that Catifa (El Katiff), on the Arabian coast opposite Bahrein, was the center of an important fishery. In the ninth century these fisheries were noted by Massoudi, one of the earliest Arabian geographers.[91] In the latter part of the twelfth century they were visited and described by the Spanish-Hebrew traveler, Rabbi Benjamin of Tudela.[92] The Arabian traveler, Ibn Batuta, wrote of them about 1336.[93] In 1508 they were noted in the account of Lodovico Barthema’s expedition to the Island of Ormus. According to him: At three days’ journey from this island they fished the largest pearls which are found in the world; and whoever wishes to know about it, behold! There are certain fishermen who go there in small boats and cast into the water two large stones attached to ropes, one at the bow, the other at the stern of each boat to stay it in place. Then one of the fishermen hangs a sack from his neck, attaches a large stone to his feet, and descends to the bottom—about fifteen paces under water, where he remains as long as he can, searching for oysters which bear pearls, and puts as many as he finds into his sack. When he can remain no longer, he casts off the stone attached to his feet, and ascends by one of the ropes fastened to the boat. There are so many connected with the business that you will often see 300 of these little boats which come from many countries.[94] Shortly following the visit of Barthema, the Portuguese under Albuquerque took possession of the principal ports of the Persian Gulf, and they imposed heavy taxes on the pearl fishery throughout the century of their retention. While under their jurisdiction, the fisheries were visited and described by J. H. van Linschoten in 1596, who wrote:
