6, The Borussian; from A. C. 1509. to 1529,
7. Mixt Observations; from A. C. 1529. to 1582.
In which year (1582) do begin the Observations of Tycho (as is affirm'd in this Edition) contain'd in 20 Books, and made in as many years, ending An. Chr. 1601, which was the end of Tycho's Life: Of which time yet there being wanting one year (viz. 1593) of the Brahean Observations, that is supply'd by the Hessian; and by a Catalogue of the Fixt Stars, made and digested by the Authority and Care of that Renowned Prince for Learning and Magnanimity, William, Landgrave of Hessen, and by the Labours of Rhotmannus and Birgius.
To all these is added a Continuation of such Astronomical Observations as were made from the time of Tycho's death unto An. 1635, by Mæstlinus and Schickardus.
Having given the Reader this short Account, I find my self obliged to give him notice withall of a Paper publish'd this year, entitled Specimen Recognitionis nuper editarum Observationum Astronomicarum, Nob. Viri Tychonis Brahe, printed at Copenhagen in 4°: wherein are remark'd by Erasmius Bartolinus the more considerable Errors in the Observations of An. 1582. In this Edition of the Histor. Cælestis, by comparing it with the Orginal, in the power of the present King of Denmark. In which Paper hopes also are given of a more correct Edition, and that of the Original itself; together with the Observations both from An. 1563. to An. 1582. and those of An. 1593; all wanting in this Edition of Ausburgh.
THese Works contain,
1. Of Astronomy 8 Books, wherein the Author hath explain'd the whole Doctrine of that Science in such a gradual Scientifick Order, that now (as himself in his own Preface intimates) a Student 'without the Aid of a Master may learn the whole by his own Study, which was formerly not easie to attain with the best Instructions.
It may be, the Inquisitive Reader will be desirous to know, what Systeme of the World it is, this Author insists on; concerning which we shall give you his own words, p. 326.
Hanc controversiam (sc. de Motu Terræ) Joh. B. Ricciolus Almag. l. 9. ea tum eruditione tum copia prosectus est, ut facile omnes in hoc negotio superaverit. Primo, Copernicanorum pro Motu Terræ Argumenta 49. deducit ac destruit; pari deinde cura, quæ contra Terræ Motum afferri solent & possunt Argumenta, vid. 77. recenset. Mihi vero, cum nihil hactenus in utramvis partem adductum videam, quod Probabilitatis metam excedat, hic immorari non est enimus. Unum est tamen ex omnibus contra Terræ Motum
