Christoph Helvig[1] (1581–1617) was a German chronologist and historian, theologian and linguist.
[3] He remained an authority cited well into the eighteenth century; Samuel Johnson's General Plan of Education described a course in this way: The technical part of chronology, or the art of computing and adjusting time, as it is very difficult, so it is not of absolute necessity, but should, however, be taught, so far as it can be learned without the loss of those hours which are required for attainments of nearer concern.
The student may join with this treatise Le Clerc's Compendium of History; and afterwards may, for the historical part of chronology, procure Helvicus's and Isaacson's Tables; and, if he is desirous of attaining the technical part, may first peruse Holder's Account of Time, Hearne's Ductor Historicus, Strauchius, the first part of Petavius's Rationarium Temporum; and, at length, Scaliger de Emendatiene Temporum.
And, for instruction in the method of his historical studies, he may consult Hearne's Ductor Historicus, Wheare's Lectures, Rawlinson's Directions for the Study of History; and, for ecclesiastical history, Cave and Dupin, Baronius and Fleury.
He became professor of Greek and Oriental languages and of theology at the University of Giessen.
