I've given you the periods at the top of the chart: early Bronze Age; middle Bronze Age from about 2100 to 1550; we date the late Bronze age from about 1550 until 1200--the introduction of iron and the beginning of the Iron Age in 1200. Prior to that, the Bronze Age, which is divided into these three periods.
