This firm was the biggest Dutch one for publishing maps in the 18th century. The late eighteenth century saw a number of successful reissues by publisher Cornelis Covens (1764-1825), who ran the famous cartographical publishing house of Covens & Mortier (1721-1866) in Amsterdam. Leonard Valk died in relative poverty: his wife had to take in the washing of their aunt to make ends meet. Leonard naturally took over the business on his father's death in 1726, and following his own death in 1746 the firm was run by Maria Valk, cousin, and wife to Gerard. The cartography, as stated on the cartouche, is based closely on the celestial atlas Uranographia, published in 1687 by the celebrated Polish astronomer Johannes Hevelius (1611-1687).Īround 1711, when he became a member of the bookseller's guild, Leonard Valk (1675-1746) came into partnership and his name started to appear alongside that of his father on the cartouches of the globes, although the earliest of these, both terrestrial and celestial, still bear the date 1700. The Valks produced several editions of 3, 6, 9, 12, 15, 18 and 24-inch diameter terrestrial and celestial globes. In 1701, he applied for a charter for making globes and the "Planetolabium", designed by Lotharius Zumbach de Coesfelt (1661-1727), an astronomy lecturer at Leiden University. Initially, they published maps and atlases, but in 1700 the company moved the shop to the building previously occupied by map and globe-maker Jodocus Hondius. Initially an engraver and art dealer, and having worked for map-sellers Christopher Browne and David Loggan in London between 16, Valk established the firm in Amsterdam in 1687. ¨in de Calverstraet bij den Dam in de Witte Pascaert¨.Gerard Valk, or Gerrit Leendertsz Valck (1652-1726) together with his son Leonard, were the only significant publishers of globes in the Netherlands in the eighteenth century, enjoying an almost total monopoly in the first half of the 1700's.
