Note that the Orientation Slice is cut precisely to the (100) before the crystal is rotated and cut at either +.25 degrees and toward the flat, or â.25 degrees and away from the flat (as described in Figure 3).
The era was called the Dark Ages also because we don't have a lot of written sources from that time period, especially from the early part of the dark ages (500 to 800 CE).
Iron-working is the one technological innovation that stands out during this period, so the Greek Dark Age is also known as the Early Iron Age. Iron-working was an innovation that seems to have been imported into Greece, not developed there, and it possibly reached Greece through Cyprus and the Near East.ome scholars have proposed a date between c. 1200 BCE and c. 800 BCE for the Greek Dark Age. Others believe that it begins in c. 1100 BCE and ends in 776 BCE, the date of the first Olympian Games (according to Hippias of Elis). A date between c. 1000 and 750 BCE has also been favoured.
