“Where was it said that all the ‘relic’ fragments of the “True Cross” could form several dozen, if not hundreds, of life size crosses?”
Not that I’m in to relics, but my understanding was that that statement was not an assessment, but merely a supposition.
Yes, I found it. It was merely a disparaging quote from John Calvin, rather than an actual assessment. In the 1870s an actual attempt to add up all of the volumes yielded a result about the third of what the size of the cross is expected to have been.
