Ernst Haeckel’s Kunstformen der Natur... love how organic these illustrations are..even used in our wedding invitations. Apparently..twenty-two varieties of slime mold are represented in Heronymous Bosch’s Garden of Earthly Delights. Yay..art history.
Druids and later “witches” were thought to shapeshift into hares for magical work. Because of this belief, according to Julius Cesar (since we all know his works on the Celts are just so very reliable), it was considered taboo amongst the Celts to eat hare in case you were eating someone who was just shifting.
