An interesting post, @slowwalker.

I've always been fascinated with the use of grotesque images of animals to ward off evil spirits.

It's quite common in the western world to see these representations on the walls of churches and cathedrals, normally sacred places, but not immune to evil influences.

Oftentimes, the grotesques would serve a useful purpose as water spouts to channel water away from the main structure and then they would be considered gargoyles - but your images are under the eaves and their use is mainly symbolic and somewhat anthropomorphic.

A feature of architecture that sounds a cautionary note, the eternal presence of evil alongside good - an image of a fallen world.

Have a good day, my friend :)
