Cargo from the remains of the oldest shipwreck to be found in the deep sea has been discovered in the eastern Mediterranean, Israeli archaeologists have said.

Hundreds of intact amphorae - ancient storage jars - believed to be 3,300 years old, were discovered 90km (56 miles) off the northern coast of Israel at a depth of 1,800m (5,905ft) on the sea bed.

"From this geographical point, only the horizon is visible all around. To navigate they probably used the celestial bodies, by taking sightings and angles of the sun and star positions.”
...
Only two of the amphorae - believed to have been used by the Canaanite people who lived in an area stretching from modern-day Turkey to Egpyt - were removed using specially designed tools, so as not to disturb the remaining artefacts.
