World's oldest example of an Astrolabe navigation tool discovered on a Shipwreck
Archaeologists have announced they believe is the world’s oldest example of an Astrolabe, early navigation tool that was used by sailors during the 15th century.
The Britain-based searcher David Mearns has discovered on a Shipwreck off the coast of Oman in 2014.
It is used by sailors to measure the altitude of the Sun this particular example is believed to date back as far as 1495 and 1500.
Aside from astrolabe, other items discovered on the shipwreck were a bronze bell, gold coins and a rare silver coin known as the ‘ghost coin of Dom Manuel.
Mearns’s company Blue Water Recoveries found the shipwreck in 1998 after researching it but excavations on the site did not begin until 2013 when the excavations began in collaboration with Oman’s Culture Ministry.
Presently, the astrolabe is with Oman’s National Museum.
