But in the past two decades, a hypothesis known as low chronology was developed whereby the pottery styles that were associated with the start of Iron IIA (as well as the monumental building program) no longer belonged to David or Solomon, but rather to later kings.Proponents of this view said that David and Solomon belonged to the simpler, far less-advanced civilization of Iron I, a period normally associated with the judges—and with decentralized, weak, unimpressive Israelite trade, institutions, government and construction.These were dated increasingly through the use of carbon dating (also known as Carbon 14 dating) rather than just pottery analysis. Josef Garfinkel at Khirbet Qeiyafa, a site located on the border of ancient Israelite territory against Philistine land, yielded remains of a hefty city wall, gates and a large public building.
However, the contention that all future and past carbon samples are 20 years too old will further muddy the waters in terms of using carbon samples to accurately date discoveries.
In that time period, they do see variations that indicate that the traditional dates were off by an average of 19 years, but in many cases, only as much as five years.
Furthermore, they deduce, that possibly, warmer weather tends to make samples appear older than colder weather.
This period covers a massive increase in building throughout Israel.
Traditionally, this building program was associated with David and Solomon.
