Shells
on churches, tombstones, and used by pilgrims:
(1) If dedicated to James the Greater, the scallop-shell is his recognised emblem. (See James.) If not, the allusion is to the vocation of the apostles generally, who were fishermen, and Christ said He would make them “fishers of men.”
(2) On tombstones, the allusion is to the earthly body left behind, which is the mere shell of the immortal soul.
