This 17th-Century ‘Supercomputer’ Could Set a New Auction Record
A rare 17th-century Mughal astrolabe, crafted in Lahore in 1612 by brothers Qa'im Muhammad and Muhammad Muqim, is heading to Sotheby's London on April 29 with an estimate of £1.5 million to £2.5 million ($2 million to $3.4 million). Weighing nearly 20 pounds and measuring the diameter of a large cooking pot, it is one of only two known astrolabes by these makers—the other resides in the National Museum of Iraq. Commissioned by Aqa Afzal, a Safavid-born deputy governor of Lahore, the instrument lists 94 cities, 38 stars, zodiac signs, and includes quadrants for trigonometry and solar calculations, blending Islamic and Sanskritic astronomical traditions.
