Israeli President Shimon Peres presented visiting Pope Benedict XVI an Old Testament that local scientists have inscribed on to a pinhead-sized silicon chip.
The Hebrew-language Bible was engraved on a 0.5 square millimeter (0.0008 square inch) chip by scientists from Technion, Israel's Institute of Technology.
According to the nanotechnology experts at the Technion Haifa Institute of Technology, the text measured less than 0.5 sq mm, which was written on a silicon surface covered with a thin layer of gold (20nm in thickness - 0.0002mm).
The veteran Israeli statesman presented the 308,428-word text to the pontiff during his visit to Israel.
The chip is in a glass case decked with a magnifying glass along with technical explanations of the nano Bible in Hebrew and English, and the first 13 verses of the Book of Genesis magnified 10,000 times.
The 86-year-old president is a known enthusiast of nanotechnology, which he has branded as the key to solving the Jewish state's security needs.
