'Aurora Consurgens'
Saint Dominic's experience drinking the Virgin Mary's breast milk made its way into alchemical illustrated manuscripts like the Aurora Consurgens ("Dawn Rising"), from the 1420's. This is one of the most unusual works I come across. Once attributed to Thomas Aquinas, now it's to a writer called the "Pseudo-Aquinas." Such manuscripts were produced for rich patrons who themselves liked to dabble in alchemy. Make of it what you will.
