An Ancient Anchor From the Byzantine Era

Two lifeguards found an ancient 600-pound metal anchor off the coast of Bat Yam, adjacent to Tel Aviv, leading to the discovery of two others  The anchor dates back to the Byzantine period of approximately 1,500 years ago and measured at 2.1 meters (nearly seven feet) long. It was found buried in the sand only 100 feet from shore.

I have to say I’m not really all that interested in the Byzantine era- but I would like to know more about the other items found:

Further explorations in the area uncovered an identical anchor and a stone anchor, much older.

Well how much older?  From what period?

IAA maritime archeologist Dror Felner said that the discoveries raise the possibility that boats anchored in the area, a fact unknown in the past. Another possibility is that the anchors were from boats that were out at sea and sought refuge from sudden storms.

All interesting questions.  Looking forward to more- especially on the older items.
