Caganers

These figures appeared in late 17th century in Catalan and environs. Wikipedia explains them in detail. Here is image search showing a full array. Here is a caganer store where the figures are sold for $19.00 each. They're also sold on Amazon. However they're described they're foremost testament that on Earth, everything sacred comes tainted with the profane, an impulse, a fact of material life, that cannot be avoided or resisted.

The Catalan pessebre, their nativity, is more extensive than mere creche, encompassing the whole town of Bethlehem and surrounding pastures including women doing ordinary things and shepherds waking with gifts, so this figure can be tucked into the scene and hidden. So along with angels singing the glory of God actually bestowing himself on Earth in a scene of high spiritual aspiration, an anachronistic figure is included having a poo, joking, now that God is on Earth and one of us, he too must deal with that residual portion.

One of the sites describing the shops selling these figures wrote, this time of year business really piles up.
