Thought-provoking: the #Astronomy knowledge and technology refined and developed by #Muslims during the #Almohad and #Nazarid reigns in #Andalucia was critical in the success of the #Spanish armada in colonizing the western hemisphere.
Below are pictures of nautical navigation instruments used by Spanish sailors. These tools were made after #Muslims were expelled from #Spain (starting in 1492 CE).
#Astronomy related instruments, refined and developed by #Muslim scholar-craftsmen during the #Almohad and #Nazarid eras in #Andalucia, are on display now at the Cuarto Real in #Granada .
Some of the knowledge and technology was a borrow from the Greek and Phoenician worlds, but the Muslim contribution to what we now know as astronomy is staggering in scope.
These are mostly reproductions: most of the originals have found their way into northern European museums.
