Here's a picture of the "Antony and Cleopatra" shrine ("Temple 0"). Note the foundation walls of Temple 1 that was built entirely over it. The floor of that temple, built by Herod for Augustus, was at the top of those walls. Sure looks like deliberate obliviation to me. (I got the date of Temple 2 wrong yesterday, it was built at the end of the 1st century CE, about 100 years after this shrine and 80 years after Herod's temple.)
Went out on a "surface survey" this afternoon organized by one of the professional archaeologists. A group of people organized in straight line walk over an area, sometimes over a period of weeks, and look for evidence of human activity. We were fairly disorganized but it was still an interesting activity.
