Engravings of ships have been found on an ancient water cistern discovered in a city in Israel’s Negev desert, Fox News.

The Roman era-cistern, which is 39-feet deep, was excavated by the Israel Antiquities Authority in the Negev city of Beer-Sheva. “After initial clearing a well hewn and plastered staircase leading into the depth of the cistern was exposed,” officials explained, in a statement.

Thinly engraved lines were found on the plaster walls of the cistern. On closer inspection, archaeologists discovered that the lines represented boats, a sailor and animal-style figures.

Whomever did the engravings had knowledge of ship construction, according to Dr. Davida Eisenberg-Degen, an Israel Antiquities Authority specialist in Rock Art and Graffiti. The cistern likely served a nearby Roman residence, she added.

The cistern was apparently in use until relatively recently – archaeologists discovered ammunition shells and parts of weapons dated to World War I in its sediment.

The find is just the latest fascinating archaeological discovery in Israel.

In a separate project, archaeologists recently confirmed the first full spelling of “Jerusalem” on an ancient stone inscription excavated in the area of Jerusalem’s International Convention Center, known as Binyanei Ha'Uma.

In another project, experts discovered a site that may offer fresh insight into the ancient biblical kingdom of David and Solomon. In a separate archaeological dig, a trove of bronze coins, the last remnants of an ancient Jewish revolt against the Roman Empire, were recently discovered near the Temple Mount in Jerusalem.

In February, archaeologists announced the discovery of a clay seal mark that may bear the signature of the biblical Prophet Isaiah.
