Hi Basser you search. It never materialized. The reason you said is a first for me. Never heard those reason before.
You mentioned the reasons, so show us or is this your opinion.
"The relationship never did take off for whatever reason, one of which was that the Vatican Library urns were not the right size and material to fit into the burial niches in Europe. They had to be made of wood if I recall right. Do I recall correctly? I am sure that you might feel it to be an important enough of a matter so I will assign you the job of researching why the relationship did not work out. Waiting for results.
Fact is this carrot dangling didn't work out. Another missed opportunity.
