This Astrolabe, dated 1628, was discovered near Isle Aux Morts, NL (a.k.a. Island of the dead),on November 26, 1981. It is in mint condition and in working order, it is indeed a very rare and valuable find for Newfoundland and all of Canada.
The owner of the famous explorer Champlain's original maps, Joe C. W. Armstrong, commented on the founding of the astrolabe: "It is an occasion for all of Canada to celebrate". The Smithsonian Institute, perhaps the world's premiere scientific and historical institute, has described the Mushrow Astrolabe as "Priceless". The former Provincial Minister of Tourism and Culture has described it as "The most significant find in our Province".
The Mushrow Astrolabe is unique in the world because it is in mint condition and it is graduated for Zenith (overhead) distance only, which is typically Portuguese. Out of twenty-one recorded known sea Astrolabes, only four are Portuguese. These are the following:
It is the centrepiece of The Gulf Museum, Port Aux Basques, Newfoundland, Canada, and is on display during the summer months.
