"Towards sunset we had cleared down to the level of the 12th step, which was sufficient to expose a large part of the upper portion of a plastered and sealed doorway"

This quote is from Howard Carter, an archaeologist who found the burial place of Tutankhamun in 1922. In this quote, he is describing the procedure of removing the particles from the entryway of the tomb. He and his group had actually worked until sunset, and had actually handled to clear down to the 12th action, which sufficed to reveal a big part of the upper portion of a plastered and sealed doorway. This was an amazing moment for Carter and his team, as it was the first indication that they had found the entrance to the burial place. It was a substantial moment in history, as it marked the start of the discovery of Tutankhamun's burial place and the treasures it contained.
