=A.D. 1623.=--Hervart--Heroart--Herwart--Hörwarth (Joannes Fridericus), son of Johann Georg Hervart ab Hohenburg, the well-known scientist (1554–1622), who during forty-five years occupied the post of Bavarian Chancellor under three reigning princes--completes his father’s work entitled “_Admiranda ethnicæ theologiæ ..._” which, Larousse says (“Dictionnaire Universel,” Vol. IX. p. 250), was published at Munich, 1624, and in which he demonstrates that the earlier Egyptian divinities were natural phenomena personified and adored under symbolic names. Michaud, who reiterates this (“Biographie Universelle,” Vol. XIX. p. 364), speaks of the edition which appeared at Munich in 1626, and he also states that, at the end of the latter, will be found “_Exacta temporum ... chronologiæ vulgaris errores_,” which is the continuation of the “_Chronologia Nova_,” left unfinished by the Bavarian Chancellor. This is, in fact, so mentioned in the only copy possessed by the British Museum, which was published by J. F. Hervart ab Hohenburg at Ingolstadii, 1623, and of which the title reads: “_Admiranda Ethnicæ Theologiæ Mysteria propalata. Ubi lapidem magnetem antiquissimis passim nationibus pro Deo-deocultum: et artem qua navigationes magneticæ per universum orbem instituerentur...._” Libri’s “Catalogue,” 1861, Part I. p. 405, No. 3703, has the following entry: “_Admiranda Ethnicæ ... ubi Lapidem Magnetem antiquissimis Nationibus pro Deo cultum commonstratur_ ...” Ingolstadii, 1623. The work itself endeavours to prove that the loadstone’s properties were well known to the ancients. The “General Biographical Dictionary” of Alexander Chalmers, London, 1814, Vol. XVII. p. 426, makes following entry: “Herwart (or Hervart) John George, Chancellor of Bavaria at the beginning of the seventeenth century, published some works wherein his learning was more displayed than his judgment, in supporting the most extravagant systems. Two of his works are: ‘_Chronologia nova et vera_,’ in two parts, 1622 and 1626, and ‘_Admiranda Ethnicæ Theologicæ Mysteria propalata, de antiquissima veterum nationum superstitione, qua lapis Magnes pro Deo habitus colebatur_,’ Monach, 1626, quarto. It was here asserted that the ancient Egyptians worshipped the magnet,” etc. (see Deveria, under B.C. 321).
