Gargoyles & Grotesques
From the 13-15th century ce. Europe saw the
birth of a new artistic/architectural style... it was called gothic.
Gargoyles and grotesques became popular images in the churches. The
theory was that demons would see these images and assume that the
devil was already present there and they should pass on by.
Originally gargoyles (from the French garguille - meaning rain spout) were
used as gutter drains, but eventually all winged beasts and demons came to
be called gargoyles.
