First, the surprise, then, the
emotion, followed by the irresistible desire to interpret, understand or
at least to begin to understand the sublime meaning of it all!
We have just visited the first spot
excavated by the archaeologist Francesco P. Eugenia Alliata in the
Grotto of the Annunciation in Nazareth. Next, we will see some
unexpected, and very exciting new historical and archeological
discoveries made during the work to clean this holy site.
In addition to the discoveries of some
floral motifs in the adjacent grotto of Conon, floral motives were found
inside the Grotto of the Annunciation which date back to between the
fourth and fifth centuries. However, what has provoked the most
historical and archaeological interest has been the discovery of
numerous symbols of the cross etched into the wall outside the Grotto
which are believed to have been carved by Christian pilgrims to Nazareth
in the Middle Ages.
Both outside and inside the cave painted areas never before
seen have been discovered along with some Greek letters.
Yet the most exciting discovery by far
has been the unearthing of the Gallery that leads to the Franciscan
Convent. This Gallery was commonly believed to have been dug by the
Franciscans to enable hidden access to the Shrine without their being
seen by others. However, further research done on the painting and
ancient graffiti now suggest that the Gallery must be even older than
what was first believed. This gallery certainly existed before the
arrival of the Franciscans in 1600 and it is believed it probably
predates even the Crusader period.
To our delight, in several layers of plaster and
superstructures that were applied on the rock, we found incisions left
by pilgrims. Until now, these incisions had not been detected in any
previous excavations or archaeological searching. The biggest surprise
was when the paintings were discovered. They are tiny fragments, not
complete works. However, they provide us with a new interpretation as to
what the original Grotto may have looked like.
The discoveries of the paintings were
made during the restoration work which is still in progress and being
conducted by specialists in the technology of archeological
preservation.
Monitoring of humidity and temperatures of the Grotto over the past months has revealed the threat of future serious deterioration of these precious painting fragments which have already been compromised by the exposure to light and the constant traffic of pilgrims. An attempt at preserving the walls of the Grotto and paintings in the 1970's by treating them with special plastic polymers has resulted in damage to some areas of the original stone matrix and even to some of the paintings.
A team of chemical and geological
experts from the University of Florence have been brought in to do the
vital restoration work to preserve for posterity this sacred site. Their
plan is to remove the entire polymer material from the Grotto walls and
through a process of highly sophisticated nanotechnology reconsolidate
the original stone structure.
The use of these polymers in the earlier restoration
work did not take into consideration the perspiration arising from
humidity and thus, a huge amount of salt accumulated and with time
seeped out through the walls damaging both the walls and the paintings.
The scientists cutting edge technology
makes possible the reconsolidation of the stone material which will
permit the salts to be released slowly from the walls over several years
ultimately leading to a point of systemic balance after which the
conservation will remain permanently enduring well beyond our lives and
those of our children.
