The Donum Dei: An Alchemical Manuscript

The Pretiosissimum Donum Dei, 'the most precious gift of God', is an important early alchemical work, with a famous series of 12 illustrations. There have been identified over 60 manuscripts of the Donum Dei, the earliest dating from the 15th century. Some of these versions ascribe the work to Georgius Aurach de Argentina [sometimes 'Anrach'] and date it to 1475, though this unverified. There are versions in Latin, German, French and Italian, and one in English in the British Library.
