Padre Athanasius explored a live volcano which had recently erupted, Vesuvius. Also explored underground in Malta. Some of the theories Athanasius came up with and were reject are true. He had access to the vast underground archives of the Vatican. There are treasures there from the pre-flood world and ancient civilizations. Some of his errors were due to reports from others which turned out to be false. Lots of his work was based in experiment but also from documents written in various languages. Just saying.
