Samar Najm Abul Huda's translation of Ahmad ibn Yusuf al Tifaschi's study of gems. Born in 1184, Al Tifaschi first learned about gems from his father, and augmented his knowledge through readings of Aristotle, Theophrastus, and Pliny, as well as through extensive travels to mines and trading centers. In 1253, he wrote what later became known as the most 'methodical and complete' work on precious stones. Gemologists of today are still astounded by the advanced observations that Al Tifaschi made in this work.

This book was released on 2014-05-10. Sky Blue Stone available in PDF, EPUB and Kindle. This book traces the journeys of a stone across the world. From its remote point of origin in the city of Nishapur in eastern Iran, turquoise was traded through India, Central Asia, and the Near East, becoming an object of imperial exchange between the Safavid, Mughal, and Ottoman empires. Along this trail unfolds the story of turquoise--a phosphate of aluminum and copper formed in rocks below the surface of the earth--and its discovery and export as a global commodity. In the material culture and imperial regalia of early modern Islamic tributary empires moving from the steppe to the sown, turquoise was a sacred stone and a potent symbol of power projected in vivid color displays. From the empires of Islamic Eurasia, the turquoise trade reached Europe, where the stone was collected as an exotic object from the East. The Eurasian trade lasted into the nineteenth century, when the oldest mines in Iran collapsed and lost Aztec mines in the Americas reopened, unearthing more accessible sources of the stone to rival the Persian blue. Sky Blue Stone recounts the origins, trade, and circulation of a natural object in the context of the history of Islamic Eurasia and global encounters between empire and nature.

Download and read online ebook Insights into Portuguese Medical History write by Maria do Sameiro Barroso. This book was released on 2022-10-11. Insights into Portuguese Medical History available in PDF, EPUB and Kindle. Despite its richness as a potential research field, the history of medicine in Portugal has received relatively little attention outside the country. This book develops some of the understudied themes of Portuguese medical history and delivers them to a wider audience by bringing together the work of a group of international scholars. Here, a unique set of innovative studies begins to uncover details of the lives, medical practice and research of some famous and less well-known Portuguese physicians, the Portuguese response to past pandemics, and analyses of a wide range of items of medical material culture and materia medica. The contributions here elucidate topics as wide-ranging as Graeco-Roman medicine and surgery, the history of spectacles, defence against plague and other epidemics, the history of medicinal emeralds and cinchonine, and echoes of the first female forensic physician in Portugal. This book will appeal to all those with an interest in the history of science, and especially those who enjoy the history of medicine and pharmacy.
