Shema transliterated into Greek alphabet in Austria inscription

From the University of Vienna, via NTResources.com, via e.t.c.:

Archaeologists from the Institute of Prehistory and Early History of the University of Vienna have found an amulet inscribed with a Jewish prayer in a Roman child’s grave dating back to the 3rd century CE at a burial ground in the Austrian town of Halbturn. The 2.2-centimeter-long gold scroll represents the earliest sign of Jewish inhabitants in present-day Austria.

Curiously, the prayer is Hebrew--the Shema from Deuteronomy 6--but is transliterated into the Greek alphabet:

ΣΥΜΑ ΙΣΤΡΑΗΛ ΑΔΩNΕ ΕΛΩΗ ΑΔΩN Α

[SHEMA IS[T]RAEL ADONE ELOE ADON A]

Hear, O Israel! The Lord is our God, the Lord is one.
