Tattenai

Tattanu or biblical Tattenai was used under Darius I. Transeuphratene Persian governor. Presumably, he was subordinate to the satrap of Babylon and the Transeuphratene Hystanes. Tattanu is known from cuneiform sources and biblical texts.

518 BC, the Babylonian " Commissioner " Šamaš - aba - usur appointed by the Jewish exiles as a witness for a supposedly in 538 BC by Cyrus II decreed the adoption of the correspondence of Tattenai in which the return of the temple vessels should be arranged by the destroyed sanctuary in Jerusalem.

Therefore Tattenai traveled specially to Jerusalem to sift spot said document because he did not own any appropriate administrative certificate. The trip was an attempt to settle the emerging tensions between the Samaritans and the Jewish returnees. Since no one was able to provide a duplicate of the certificate management, Tattenai did not meet the oral request, handed over to the temple treasury, and came away empty-handed on the way home.
