The Amathus bilingual was an inscription on black marble from ancient Cyprus.
It features a bilingual dedication inscribed in both Eteocypriot and Greek. Discovered and published in 1914 by Ernst Sittig, the inscription has been important to the decipherment of Eteocypriot, thought to be related to Luwian. The monument was lost during its transport to the United States.
The Cypriot or Cypriote syllabary (also Classical Cypriot Syllabary) is a syllabic script used in Iron Age Cyprus, from about the 11th to the 4th centuries BCE, when it was replaced by the Greek alphabet. It has been suggested that the script remained in use as late as the 1st century BCE. A pioneer of that change was King Evagoras of Salamis. It is thought to be descended from the Cypro-Minoan syllabary, itself a variant or derivative of Linear A. Most texts using the script are in the Arcadocypriot dialect of Greek, but also one bilingual, the Amathus bilingual, a Greek and Eteocypriot, was found in Amathus.
