The Greek island of Samos is about 470 km² and lies about a mile and a half off the coast of Turkey at about 36°16'N 26°45'E. It is the home of at least two mathematicians, Aristarchus who lived between 310 and 250 b.c., and Pythagoras, who lived between 560 and 480 b.c. 
     Pythagoras was born on Samos, the son of Mnesarchus and Pythias, but left Samos and founded his school and philosophical movement at Cretona, a Greek colony in southern Italy. He died in Metapontu.
     The stamp shows Ν. ΣΑΜΟΣ, Island of Samos, with the towns of Samos and Tegani. The map is not an ancient map, although its presentation is of such a map.
     There are three other stamps in the set issued by Greece in 1955. Two show a Roman coin from Samos with Pythagoras seated. The other stamp is a graphic presentation of the Phythagorean Theorem, a² + b² = c².
