Welcome to Martin Brunold, Maker of astrolabes

Martin Brunold

Martin Brunold is a maker of astrolabes and related instruments since 1975. But since 1997, the reproduction of ancient astronomical instruments is his main profession. The brass reconstructions are made by hand but also modern tools are used as for example the computer for calculations. The instruments follow antique originals but are not exact copies or facsimiles. The stars, shifting their positions during the centuries due to precession, are not «corrected» to our epoch. Corrections enable us to use the instruments today. The information is found in the detailed manual (German/English). The instruments are not lacquered and therefore need some care until a natural patina has developed. Each instrument is signed with the literals "MB" and is numbered.


Technique of construction

The technique of construction corresponds mainly to the past centuries: drilling, sawing, filing, soldering, screws. But also modern technique is used: e.g. gluing, or the computer for calculations. The inscriptions are not engraved but etched. The polished brass is not laquered for aesthetic reasons. Until a natural patina has developed, some care is needed to avoid stains: rub the instrument with a towel.
Due tho the handcrafted nature of production, several weeks may be required for delivery, but I endeavour to carry most of the instruments in stock.
