During the long centuries of Byzantine rule, many circumstances conduced to the animation of trade and proper cultivation of the fertile soil. Cyprus was long regarded as a veritable harbour of refuge, not only by those inhabiting the neighbouring Asiatic continent, but by the persecuted victims of various religious denominations, many of whom being quiet, industrious men, settled down at once in the country of their adoption as skilful tillers of the soil; whilst the Armenian and Syrian refugees taught and improved the arts of trade and commerce. The introduction of the silkworm into Cyprus must, however, be regarded as a main cause of its long prosperity. Until that time the wearing of silk was confined entirely to the highest classes, and it could only be procured, at enormous cost, of merchants travelling from India and China. In the year 557 two monks brought a quantity of silkworms’ eggs from India to offer them to the Emperor Justinian, who, appreciating their commercial value, caused them to be distributed over different provinces. In no place did their culture succeed as in Cyprus; the warm soft air, rarely agitated by wind and storm, exactly suited their requirements, and in a very short space of time the southern coasts, and other parts, were covered with mulberry trees for their sustenance, and the celebrated silk factories established and in full work. The rule of the Arab in Cyprus brought on the contrary decadence and misfortune in its train. These sons of the desert destroyed all before them, churches and temples were laid in ruins, and books committed to the flames. Once, however, settled in the conquered dominion, they gave themselves up to the enjoyment of their new possessions. Jews and Christians were employed in building new palaces, and in translating into Arabic the poetry of Persia and works of Eastern lore. For their own share of improvement the Arabs devoted themselves to the cultivation of plants, and arranged splendid and well-irrigated gardens, which they filled with trees and shrubs brought from Egypt, Syria, and Arabia.
