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.
