PORTILLA, J. Gregorio  and  MORENO, Freddy. A manuscript of the late seventeenth century: first manifestation of an astronomical and chronological autochthonous study in the Nueva Granada. Rev. acad. colomb. cienc. exact. fis. nat. [online]. 2019, vol.43, n.167, pp.255-272. ISSN 0370-3908.  https://doi.org/10.18257/raccefyn.884.

The existence of a manuscript that deals with astronomy and chronology written in the late seventeenth century by Antonio Sanchez de Cozar, a humble priest of indigenous descent, has gone unnoticed by historians of science in the country even though in the mid-nineteenth century it had been given to know as a literary work. In this paper a synthesis of the content of this manuscript is presented, as well as an analysis of some relevant aspects that show an original and independent thought of the author, such as his cinematic proposal of the movement of the heavens, the introduction of a sky between Mercury and the Moon and the proposed reform of the Gregorian calendar. The manuscript also con tains the first astronomical ephemerides made in Neo-Granadian territory consisting of lunar phases and eclipses whose times of occurrence are referred to the local time of a town of the New World: the municipality of Velez. ©2018.

Keywords : Geocentric model; calendar; chronology; ephemerides: eclipses.
