The Hispanic Society of America possesses three pairs of the Valk globes, each apparently dated 1750, though in some instances, as noted below, these dates have been altered by skilfully cutting out the last two figures of the original and inserting the number 50. The diameter of each of the largest pair is 46 cm. (Fig. 120). Each is supplied with a graduated meridian circle of brass, the celestial being furnished with a brass hour circle and pointer, and the terrestrial with a brass quadrant of altitude. Each is further furnished with a broad horizon circle of wood on which has been pasted an engraved paper giving the names of the signs of the zodiac, the various chronological signs, such as golden numbers, epacta, and dominical letters, the names of the months, and points of the compass, including both the old and the new nomenclature for the directions of winds, as “Borro Lybicus” or “Noord-West,” “Zephyrus” or “West.” The under supports of the globes consist in each instance of four turned columns attached at their lower extremities by crossbars on which rests a circular turned plate 42 cm. in diameter. From the center of these plates rises a post 10 cm. in length through a notch in which the brass meridian circle is made to pass in moving the globes to an adjustment for any desired altitude. The gores of each are twelve in number, those of the terrestrial globe having an equatorial mounting while those of the celestial globe have an ecliptic mounting, that is, the meridian lines pass from pole to pole of the ecliptic instead of from pole to pole of the equator. In each, the gores have been truncated twenty degrees from the poles, the polar space being covered by circular discs. The engraving of both the terrestrial and the celestial map is exquisitely done, and much of the color originally applied by hand yet remains. The several figures representing the constellations are copies of the figures as represented by Hevelius in his ‘Prodromus Astronomiae,’ and reference to this great astronomer is made in the title legend quoted below. These figures are among the most artistic representations to be found on any of the globes of the period, which the author is preparing to reissue in facsimile as a by-product of these globe studies.
