Among the best known of the Portuguese writers is Duarte Barbosa, who wrote a detailed account of trade and society in south India. Later, after 1600, we find growing numbers of Dutch, English and French travellers coming to India. One of the most famous was the French jeweler Jean-Baptiste Tavernier, who travelled to India at least six times. He was particularly fascinated with the trading conditions in India, and compared India to Iran and the Ottoman empire. Some of these travellers, like the Italian doctor Manucci, never returned to Europe, and settled down in India.
