  5. Rare scientific instrument in National Museums Scotland's collection marks its 1000th anniversary.
    The object is an #astrolabe, an intricate brass instrument made in 11th century Spain, which was used for charting the position of the stars. One of Europe’s oldest surviving signed and dated astrolabes, the object was made in Cordoba by Muhammad ibn al-Saffâr, and is dated 417 AH (the Islamic calendar), which equates to 1026-1027 AD.
