Description: This is a silver-plated mariner's astrolabe made by Nicolao Ruffo and dated 1645. The astrolabe was found by Gigi Fernandes Corcia, an experienced diver and full time member of the Arqueonautus dive team, during the survey and excavation of a wreck site at Passa Pau on the island of Santiago in November of 1999. The astrolabe was found associated with other wreck material of mid-seventeenth century date within a complex of deep gullies and caves at a depth of 7 to 12 meters. There was little or no site contamination with extraneous material. This astrolabe has been catalogued as the 84th astrolabe in existence with The National Maritime Museum at Greenwich. It is in the collection at The Mariners' Museum in Newport News, Virginia.
