In
1979, Mark Lehner and James Allen started work on the first
comprehensive mapping of the Sphinx. They studied its structure and
geology and documented every detail they could, from the ancient masonry
layers and tool marks to the geological stratification of the
surrounding area. Their goal was to determine how and when this iconic
monument was built and to document its then-current state of
preservation.
For
more than 35 years most of this data remained inaccessible, but thanks
to a grant from ARCE's Antiquities Endowment Fund the original project
data is now online and available to the public for study. This archive
is especially important as many of the details documented at the time
are no longer visible. If you'd like to search the data yourself, good
starting points are the project home page or try browsing some of the over 5500 photographs and 364 maps and drawings and see what you find!
While
preparing the Sphinx Project data to go online, we realized it was the
perfect time for us to revisit the Sphinx itself. Under the Direction of Zahi Hawass, Field Directors Mark Lehner and Glen Dash started the Return to the Sphinx Viewing Project
this year to document the changes that have occurred over the
intervening years. In addition to a systemic survey, we were able to use
new technologies to take a (literally) deeper look by using ground
penetrating radar to peek under the base of the Sphinx in search of new
information on its internal structure and to look for evidence of
unknown grottoes. The data from this new work is still being analyzed,
but our preliminary results will be published soon. Stay tuned!
