Paul Koudounaris is a man who is sometimes referred to as "Indiana Bones." That's magnificent on it's own, but there is a reason! He has become famous for unearthing ancient relics and taking gorgeous photographs of them. His speciality seems to be ossuaries and earthly remains associated with the church. There are a couple of big beautiful books out that collect this stuff and you should buy them. The photos above are I believe primarily of Catholic saints discovered in catacomb vaults. These guys are around 400 years old and still killing it.
Something else to consider: Indiana Bones & The Catacombs is a delicious sounding band name. Say it aloud, won't you?
