Biography
According to his college records, Sinapius was born in Bořenovice in Moravia in a lower-class family. He initially worked as kitchen helper at the Jesuit school at Český Krumlov, but was eventually admitted to the of poor students in 1590. Sinapius eventually graduated from the Krumlov Gymnasium, where he studied poetry and rhetoric, and became a pharmacist himself. There he also worked in the college's pharmacy, on topics involving chemistry and herbalism, under the overseeing of Martin Schaffner.By 1598, he started studying Aristotelian philosophy at the Clementinum college in Prague, and at the same time oversaw the kitchen and pantry, but continued working in chemistry and pharmacy. However, Sinapius was not satisfied with the teachings there, musing over Barbara Celarent, instead of studying physics and the origins of nature. Because his herbal skills to treat illness impressed, he was allowed gardening near the river Vltava, under the Bräke. Here he grew herbs and set up a laboratory at Smíchov, the Clementinum's botanical garden. There, or at the garden, he distilled a very popular aqua sinapis whose sale made him a wealthy man.
In 1600, he became the administrator of the Jesuit college in Jindřichův Hradec, and in 1606 he became capitaneus and administrator of the properties of the St. George's Convent in the Prague Castle. In 1607 he was named imperial chemist by Emperor Rudolf II. In return for curing the emperor of a grave disease, he was ennobled with the title "de Tepenec", presumably after the medieval Tepenec Castle near Olomouc. He lent Rudolf II money and received from him in return an estate around town Mělník. He also supported students of the studies of Catholic theology financially.
In the religious disputes of the early 17th century, Sinapius strongly defended the Catholic side. He became the administrator of the Mělník Castle but was jailed in 1620, when the Protestants took charge of the town. Subsequently, was exchanged for another prisoner and exiled, but later, after the failure of the Bohemian Revolt, he returned to Mělník and lived there the rest of his life.
He died in 1622, from a horse-fall that he had suffered a year before. Two days before his death he was moved to the Clementinum in the care of the Jesuits, and left them the sum of 50,000 gold coins and his Mělník estate. He is buried in the Church of St. Salvator in the Clementinum.
