Of the multitude of ancient Greek producing and exporting centers, which exported their goods, especially liquids in amphorae, only a small number of them applied stamps to commercial amphorae: Thasos, Sinope, Rhodes, Chersonese, Cos, Knidos, Mende, Samos, etc. Most of the times the stamp consisted of text (legend), which contained the function and name of the magistrate and the manufacturer or only of the manufacturer and a symbol (emblem). Some cities used only the legend, others used both the legend and the emblem. The emblems often had different images: from various objects to animal and human images. The most diverse emblems appear on stamps on Sinope and Thasos amphorae. Among the anthropomorphic emblems, the most common are the male ones, representing the protective gods – Hermes, Heracles, Helios, Satyrs, Poseidon, etc. Sometimes, female faces can also be found among the emblems. Similar to emblems with male faces, those featuring female faces represented deities of the Greek Pantheon, such as Athena, Artemis, Hecate, Nike, Demeter. Some deities are not to be found on Greek amphora stamps, among them is the goddess of beauty – Aphrodite, or the goddess Hera (wife of Zeus), Persephone or Hestia, Iris or Cybele. The Greeks most likely used as protective emblems and images of deities which offered protection (in cases with female representation), as they believed these gods had a special role and place in their trade with other countries, often long, arduous and, sometimes, dangerous.
