The Letoon trilingual, or Xanthos trilingual, is an inscription in three languages: standard Lycian or Lycian A, Greek, and Aramaic covering the faces of a four-sided stone stele called the Letoon Trilingual Stele, discovered in 1973 during the archeological exploration of the Letoon temple complex, near Xanthos, ancient Lycia, in present-day Turkey. It was created when Lycia was under the sway of the Persian Achaemenid Empire. The inscription is a public record of a decree authorizing the establishment of a cult, with references to the deities, and provisions for officers in the new cult. The Lycian requires 41 lines; the Greek, 35 and the Aramaic, 27. They are not word-for-word translations, but each contains some information not present in the others. The Aramaic is somewhat condensed.
