A pair of rare Valk table globes published by Gerard and Leonard Valk in Amsterdam in 1750 and 1700. The Dutch globe makers Gerard Valk (1652-1726) and his son Leonard Valk (1675-1746) were the only significant publishers of globes in the Netherlands in the eighteenth century. The design of their globes was completely new and incorporated the latest geographical and astronomical discoveries and are hence the most accurate globes for that time. The pair includes a terrestrial and celestial globe with a diameter of 39 cm. (15 in.) each with 12 engraved gores and two polar calottes over a paper-maché hollow core, made up of two hemispheres joined at the equator and covered with a layer of plaster. Each globe is mounted in a new oak Dutch-style stand, the celestial globe with a facsimile paper horizon ring. Including the oak stand each globe has a height of 59 cm. (23 in.). The terrestrial globe in its third state, the celestial in its second state. A beautiful and eye-catching set of these rare globes.
