- W4252531713 abstract "THE Observatory of the University of Leyden was founded in 1633 and celebrates its tercentenary this year. Prof, W. de Sitter has written a commemorative brochure which is illustrated by many photographs and reproductions of old prints, and describes the history of the Observatory from its foundation down to the present day (Haarlem: Joh. Ensched en Zonen). Leyden is not quite the oldest active observatory. The Vatican Observatory was founded by Pope Gregory XIII, the reformer of the calendar, in the sixteenth century. But Leyden is the oldest of the seventeenth century observatories, the others, in order of foundation, being Utrecht, Copenhagen, Paris and Greenwich. Amongst the early scientific workers mentioned by de Sitter is Jacobus Golius, the founder, who was led by the corrupt state of the Greek texts to study the ancient mathematicians in the Arabic; he possessed a very fine Arabic edition of Appolonius, but could not be prevailed upon to publish a Latin translation of it. Actually, the first Latin translation of Appolonius was published by Halley in 1710. Few observations were made at Golius's observatory. For more than a century the observatory was located on the roof of the University, and was maintained as much for instructional as for scientific purposes. As the public had the right to look through the telescopes at any time, the observers were often hindered in their work." @default.
