1]Why would one expect Boudet to refer to a cave he discussed with other priests in 1912, in a book he wrote in 1886, a gap of some 26 years? Perhaps Boudet learned of this votive cave later? Stop using tunnel vision i say!
2] As Boudet never mentioned a cave of immense significance in his publications this new piece of information must be fake? And that is despite Boudet being an amateur archaeologist to boot? And yet, on that note Boudet never wrote about any of the artefacts he found as an amateur archaeologist - but we know he did because others at the time discuss being given the artefacts and in one case provided a photograph. Therefore there are things that Boudet knew about which he never mentioned - ditto maybe a cave he was aware of?
3] I am trying to locate the source for this article. In the meantime it would seem the priest Destram - perhaps - the abbé Destrem - was linked to the church of St. Martin de Limoux and later with Notre Dame de Marceille. Around the same time Vannier, was then superior of the Vincentians of ND Marceille. This would explain why Boudet knew these priests as i believe Boudet did have associations with Marceille.
