TITLE (translated): Uranographia, showing a most accurate depiction of the constellations and the conspicuous stars in the individual constellations, which is adapted from the observations of the matchless astronomer Johannes Hevelius for the end of the year 1700. Moreover, by a new method invented by Lotharius Zumbach, Doctor of Medicine and a famous mathematician, the horizon at the meridian of Amsterdam is added, showing accurately for more than 200 years the syzygies of the moon, as well as the common years and the bissextiles. By the labour and enthusiasm of Gerard and Leonard Valk from Amsterdam, 1715. With privilege. DEDICATION (a leaf encircled cartouche between Hydra and Argo.): VIRO / AMPLISSIMA DIGNITATE / ac / MERITORUM SPLENDORE / CONSPICUO / IOHANNI TRIP, J.U.D. / Reipublicae Amstelaedamensis / CONSULI GRAVISSIMO, / Societatis Indiae Orientalis / MODERATORI INTEGERRIMO, / Toparchae in berkenrode / IUSTISSIMO, / &c. / URANOGRAPHIAM / hic ea, qua par est, / reverentia / D.D.D. / GERHARDUS et LEONHARDUS / VALK. (Translation): To Johannes Trip, J.U.D., a man noteworthy for is most splendid deserts and for the brilliance of his virtues, the most eminent consul of the State of Amsterdam, the incorruptable director of the East India Company, most upright Lord of Berkenrode, etc., the Uranographia is given and dedicated with equal reverence, by Gerhard and Leonard Valk.

Complete with the Equator, the tropics, the polar circles, a half equinoctal colure, a half circle of declination through 30 degrees. Ecliptic, circles and parallels of latitude every 5 degrees. The equator and ecliptic are graduated. The stars / constellations are represented as their figures, and their names are displayed in Latin. There is a legend that is crowned by the sun. There is an attractive “Sextans Uraniae” situated just below “Leo.” Established at the end of the previous century by Gerard Valk, and assisted by his son Leonard, the firm became the only publisher of globes in the Netherlands in the 18th century. In Amsterdam Gerard began his publishing firm producing maps and atlases in co-operation with Petrus Schenk about 1680. It was about 30 years later that he began to publish globes with his son. After the death of Leonard, the firm continued under the stewardship of his widow, Maria Schenk, and towards the end of the 18th century the globe factory came in to the possession of Cornelis Covens.

The globe is in fine condition, cleaned and revarnished, the gold embossing has been supplemented in certain places. The colouring is fine and original, as has a lovely looking ‘aged patina’. The celestial figures are finely engraved and rendered in truly glorious and eye-catching detail, including gold embossing to the stars and some constellations, and to the decorative sextant.

Provenance: private collector from The Netherlands.
