From Wikipedia:
Chymical Wedding of Christian Rosenkreutz (Chymische Hochzeit Christiani Rosencreutz anno 1459) was edited in 1616 in Strasbourg (annexed by France in 1681), and its anonymous authorship is attributed to Johann Valentin Andreae. It is the third of the original manifestos of the mysterious "Fraternity of the Rose Cross" (Rosicrucians).
It is an allegoric romance (story) divided into Seven Days, or Seven Journeys, like Genesis, and tells us about the way Christian Rosenkreuz was invited to go to a wonderful castle full of miracles, in order to assist the Chymical Wedding of the king and the queen, that is, the husband and the bride.
This manifesto has been a source of inspiration for poets, alchemists (the word "chymical" is an old form of "chemical" and refers to alchemy – for which the 'Sacred Marriage' was the goal [1]) and dreamers, through the force of its initiation ritual with processions of tests, purifications, death, resurrection, and ascension and also by its symbolism found since the beginning with the invitation to Rosenkreutz to assist this Royal Wedding.
