An interdisciplinary team, have managed to discover a new ink inscription, invisible to the naked eye, written on the backside of a well known inscription

The original inscription, dating to the last phase of the Kingdom of Judah in the First Temple Period (on the eve of its destruction by Nebuchadnezzar), was found in the 60's during the excavations of Tel Arad by Yohanan Aharoni. Since its discovery, the inscription have been displayed in Israel Museum for half a century, and was carefully examined by many researchers. However, nobody noticed that there is yet another inscription hiding on its backside. Three Applied Mathematics Ph.D candidates (Shira Faigenbaum-Golovin, Arie Shaus & Barak Sober) have developed a multispectral based imaging method, dedicated for ink inscriptions over clay shards. In the course of their research, they have brought a number of inscriptions, to be imaged in the multispectral imaging laboratory built in the Nuclear Physics department. The computer expert of the department, which became the photographer as well (Michael Cordonsky) suspected he saw something on the backside of this inscription, and decided to image it on both sides. To the amazement of the researchers, a whole new inscription have been discovered. The decipherment and reading of the inscription was performed with the help of a postdoc from the department of Archaeology (Dr. Anat Mendel Geberovich). This newly found inscription, is most probably a continuation of the letter written on the front side and is dealing with the exchange of wine and money between two colleagues (friends) - logistic personnel in the army of the Kingdom of Judah
