An artifact found in the wreck of the Esmeralda ship belonging to the
Vaska da Flota, in the waters near Oman, is the oldest known instrument
for navigation.! ....
Marine archaeologists claim that it is the oldest astrolab, an instrument used by sailors to determine the time, the position of the Sun, the Moon and the stars during the journey. It is believed that this instrument - astrolab, dates from the period between 1495 and 1,500 years.
Astrolab was found in 2014 in a wreck of a Portuguese exploration ship that sank during the storm in the Indian Ocean in 1503.
The ship was called "Esmeralda" and was part of a fleet led by Portuguese explorer Vasco da Gama, the first person to directly fly from Europe to India.
"It is a great privilege to find something so rarely, something historically important, something that archaeologists will study," British astrologer David Merns, the team leader who found (the oldest in the world) astrolab, the oldest astrolab navigational instrument
The bronze disc diameter is 17.5 millimeters, and it is thinner than two millimeters.
Although initially experts seemed to find nothing important on astrolab, laser marking at University "Vorvik" detected labels on the edges of the disk, and between each spacing of five degrees.
Thanks to this, seafarers could measure the sun's height over the horizon at noon and thus determine the location. Astrolabs are very rare, and this is a total of 108 that was found.
