Hi! We love a niche topic, and this is proving to be a bit of a challenge…
Our best result is a journal article from 1995, “Miró’s Mystical Mollusks” by Corinne Mandel, viewable for those with JSTOR access. A preview of the text:
“Claudius Aelian considered the snail to be astute by dint of its ability to slither in and out of its shell, and in this way to evade birds bent on the kill. In the Old Testament, conversely, those creatures who slither on their stomachs, including the snail, were listed as forbidden foods. Such was not the case with the ancient Romans, whose gastronomic art led them to devise rather sophisticated methods of fattening land snails, one of their favored foods. Delightful though the snail may have been to the taste, it was thought to be altogether too paranoic on account of its insistence on carrying its house everywhere it went. The snail accordingly came to signify mistrust and deception” (pg. 117).
Probably not the precise thing you’re looking for, but interesting stuff nonetheless!
