Morgenröte im Aufgang

Twelve years after the vision in 1600, Böhme began to write his first book, Morgenröte im Aufgang ("Dawn of the Day in the East"). The book was given the name Aurora (sometimes translated into English as "The Day-spring") by a friend. Böhme originally wrote the book for himself and it was never completed. A manuscript copy of the unfinished work was lent to Karl von Ender, a nobleman, who had copies made and began to circulate them. -- Wikipedia
