Note 438 — Chapter VII · The Educational Work of the Jesuits in the Nineteenth Century.

Father Hagen’s Synopsis has been called a “splendid contribution to the history and progress of mathematics,” Nature, London, June 7, 1894; “a colossal enterprise,” Revue Bibliographique Belge, Sept. 30, 1891; “a really grand work,” Professor Cantor, in Zeitschrift für Mathematik und Physik (hist.-lit. Abth.), XXXVII, 4, p. 151. “One must be astonished how one man can master such an amount of learning,” Zeitschrift für math. und naturw. Unterricht, XXVII, p. 43. The American Annals of Mathematics (1893, vol. VII, No. 3) call it a “monumental work” and say: “A more useful labor than this in the present condition of mathematical literature can hardly be imagined; moreover, it calls for all but the very highest, that is creative mathematical power; in particular, for immense erudition; an unerring logical instinct ..., but above all for untiring industry, etc.”—Father Hagen’s Atlas Stellarum Variabilium was also highly praised, v. g. in the Bulletin Astronomique, 1900; in the Vierteljahrsschrift, XXXV; in the Leipzig Litterarische Centralblatt, 1900, No. 4, and 1902, No. 26.
