AN EARLY 19TH-CENTURY DUTCH ‘ROEDEN’ (ROD) ALIDADE RULE BY BRENER, NAMUR
the brass bedplate secured to coromandel wood base, signed as per title and further inscribed Dubbe De Schaale / Generalitait Schaale van 160 Rýnlan dse Roeden with measurements and Gunter squares delineated along length, each end with hinged sights, each with two further hinged sights, contained within original felt-lined leather-covered box with securing hooks and handle -- 24in. (61cm.) diameter
At the date this was made, many variations of rod measurement co-existed. The Dutch roede was generally shorter than the English rod (16.5 ft) however the subdivisions, or voeten, varied dramatically from place to place and there could be anything between 7 and 21 voeten to a roede. Louis XIV invaded Namur 1692-5 when he built Namur castle. Napoleon re-occupied the area from 1794-1815 when he introduced his Code Napoleon unifying all these measurements and making instruments such as this lot obsolete.
£300-500
