Daniel Angelocrator (October 19, 1569 - July 30, 1635) was a German Reformed minister, theologian, and mapmaker. He was born Daniel Engelhardt in Korbach, and studied theology at the universities of Marburg and Franeker. Upon adopting Calvinism - a decision that caused a break with his family - he relocated to Geneva. In Switzerland, he taught in high schools; later, he became a minister in Germany. The Landgrave of Hesse-Kassel made him Archdeacon of Marburg in 1607. During this period, in 1617, he published the first edition of his book on weights and measures, 'Doctrina De Ponderibus, Monetis, et Mensuris per totum terrarum orbem usitatis' (Weights, Measures, and Coins Used Throughout the World.) He was a delegate to the Synod of Dort in 1618. The Thirty Years' War uprooted him from Hesse-Kassel, and he became minister of Gudensberg - only to be completely dispossessed by Imperial troops sacking the city in 1626. He relocated again in 1627 to Köthen. During his time there, he published a further edition of his Doctrina De Ponderibus, which contained a new world map Novum Orbis Terrarum Schema, in Plano sic Descriptum. Despite its likely invention by da Vinci, Angelocrator claimed the projection to be his own composition, while its geographical information was drawn from Geelkercken. He died in Köthen in 1635.
