Within it, and specifically in the geographical region that was part of Phoenicia, is a concentration of hoards dated between 1200 and 800 BC. There is no other known such concentration of silver hoards in contemporary Mediterranean, and its date-range overlaps with the reigns of King Solomon (990 - 931 BC) and Hiram of Tyre (980 - 947 BC). Hacksilber objects in these Phoenician hoards have lead isotope ratios that match ores in the silver-producing regions of Sardinia and Spain, only one of which is a large island rich in silver.
