Yes, I asked for the sources.
I never criticised Henry Conway. I didn't deny Gibson's assertion that the former Pope bought 30 sets of vestments because it may be true. I criticised Gibson's scurrilous attempt to tar Benedict with the same brush as Leo X because the vestments were similar to those of the medieval pope. You seem to think that the inference is legitimate.
I did search the Internet but apart from the Star Register, found little else on the subject.
I am no fan of Rocco Palmo either but I didn't  find anything particularly untoward in the piece he wrote; a bit of 'August' journalism perhaps but quite innocuous, certainly not offensive or accusatory.
Who knows or even cares where a pope's shoes, clothes, vestments, sunglasses or possessions come from, whether he buys them or they are gifts?
