1. Angelus Johannes, Almanach novum atque correctum … calculatum super anno domini 1510 (Vienna, [1510]); idem, Almanach novum atque correctum … calculatum super anno domini 1512 (Vienna, 1512). Both almanacs are extremely rare: The 1510 is extant in Gniezno, Cathedral Chapter Library, Inc. 43e; Vienna, University Library, I. 233605; Munich, Bavarian State Library, Res. 4° Eph. astr. 155/2 (incomplete); the 1512 in Vienna, Austrian National Library, 72.J.114(3); Graz, University Library, I 4070 (incomplete); Munich, Res. 4° Eph. astr. 155/3. Both almanacs contain a preface, an annual ephemeris in twelve folios, the canon from Johannes Regiomontanus's ephemerides published in 1474, and a three-folio abridgment of some rules for astrological prognostication that Erhard Ratdolt had appended to his 1484 edition of Regiomontanus's ephemerides. Angelus's 1510 work presents only planetary longitudes as had Regiomontanus; the 1512 almanac, however, also lists planetary latitudes at 10-day intervals, following the pattern established by Stöffler Johann and Pflaum Jacob, Almanach nova plurimis annis venturis inservientia (Ulm, 1499). For typographical descriptions of Angelus's almanacs, see Dolsch Walther, Bibliographie der österreichischen Drucke des XV. und XVI. Jahrhunderts, i/1: Trient-Wien-Schrattenthal (Vienna, 1913), 69–70, 73–74; Verzeichnis der im deutschen Sprachbereich erschienenen Drucke des XVI. Jahrhunderts (Stuttgart, 1983–), E1196–7.

Tabula primi mobilis Joannis de Monteregio (Vienna, 1514), sig. aa6r; Rheticus Joachim Georg, De libris revolutionum Copernici narratio prima (Gdańsk, 1540), sig. Iir. None of the recent translators of the Narratio prima explored what Rheticus or Copernicus might have known about Angelus's work.
