An Urban Temple. Maritime Magic of the Rotting Docks...

Rainbow ribbons are one of my favorite features of May Day and Midsummer festivals. The days of fire and sun are upon us and so rise our wants, our wishes. The entire season is one for fortunes (what season isn't?), and feelings and ribbons are the banners young lovelorn lasses could tether their wishes to. Favours of the devil or the fairfolk, ribbon magic is sweet and simple.

Folklorist Cora L. Daniels mentioned in her Encyclopedia of Superstitions, maidens would go strewing rainbow ribbons during seasonal festivities, and also mentions that a yellow ribbon was lucky to find “especially if it is floating on water; it presages gold.”

According to other regional love charms, sleeping with a blue or a pink ribbon under your hip at night was said to draw the boy or girl you love. Green ribbons sewn into a christening gown might have been employed to help children see fairies. Ribbons employed in agricultural observances and divination appear to be nothing new; I totally hope to make more time to tether my work to the little magics like these.

In American regional folklore, there are a lot of ways to diagnose medical and magical maladies- including blending olive oil and water as a diagnostic divination tool.
According to sources found in the California Folklore Society's Western Folklore as well as Popular Beliefs & Superstitions (Hand, Wayland), if one suspected their headache was of supernatural origin, they were to pour olive oil into a saucer of water and if the oil formed the shape of an eye, your headache would go away. Sometimes, the charm calls for the oil-eyes to be cut with scissors before tossing the water out.
Another charm calls for pouring oil in the shape of a cross. If it stayed that way, your ailment would ease.
