The department of the Mediterranean Archaeology of the Archaeology Museum in Kraków possesses twenty unpublished and one published amphora handle stamps. These handles were collected and later donated by Jarosław Sagan, the curator of the Museum before the Second World War, in which he joined the British Force in Palestine and collected archaeological materials in Egypt and Sudan. Seventeen out of the twenty-one stamps are from Ras el-Soda near Alexandria in Egypt, famous for its temple of Isis built in the second century CE. One stamp is from El-Kantara, which I tentatively identify with El-Qantarah el-Sharqiyya in northern Sinai, about 50 kilometres south of Port Said. Another stamp is also from Egypt but from unknown provenance. The other three are from unknown provenance. What follows is the catalogue of the stamps categorised according to the place of production. One stamp is Thasian, one is unidentified, and the other nineteen are Rhodian.
