First Edition of Halley's definitive Apollonius, one of only four hundred copies, containing the first edition of the first four books in the original Greek, and Halley's translation from the Arabic of Books V-VII, making it the first, and the only complete, edition of this work by Apollonius. Sir T. L. Heath in 1896 called it "a monumental work, beyond praise alike in respect of its design and execution" (Carter, A History of the Oxford University Press, p. 242). Books V-VII of this work were believed lost to the Western world until a German scholar, Christian Ravius, bought a manuscript in Arabic of the whole work, except Book VIII, at Istanbul in 1641. It is believed to have been translated from the Greek in the ninth century by Thabit ibn-Korra of Haran. Ravius published books V-VII in Arabic with a Latin translation at Kiel in 1669 (Carter, loc. cit.). A page of the book is illustrated in Brian J. Ford's Images of Science (British Library, 1992), praising the artistry of the geometrical woodcuts.
