Iran 1956 – Nasir al-Din al-Tusi
Nasir al-Din al-Tusi (1201–1274), also known simply as Nasireddin, was a Persian scientist who set up an
observatory at Maragha (the modern Maragheh) in 1259 where he compiled a star
catalogue and tracked planetary motions with large quadrants. The resulting
tables, published in 1272, remained in use until the time of Copernicus. As
well as astronomy, al-Tusi made major contributions to many other areas of
science including mathematics and biology.
This set of three stamps was issued as an early commemoration of the 700th
anniversary of his death. They depict al-Tusi’s tomb at Maragheh; an astrolabe, an Arabic star-sighting device about which he
wrote a treatise; and a supposed representation of the man himself.
Unfortunately the stamps were poorly printed.
