Alphonsine Tables - Oblique ascencions for the I Clima

Summary

[edit]
Description
Español: Traducción desde las Tablas Alfonsíes, Incunable 1612, obra de Juan de Sajonia (astrónomo) y publicado por Erhard Ratdolt en 1483. Agregüé unas columnas en el actual sistema decimal, correspondiente al sistema sexagesimal ptolemaico.

Esta tabla corresponde a uno de los siete climas o clímatas ptolemaicos, el I clima (Meroe). Las Horas Desiguales corresponden a las horas diurnas desiguales en grados (de tiempo), en función de la longitud de Sol siendo este el argumento en la columna Grados Iguales (Líneas de Números). En un día cualquiera del año, una hora diurna desigual es una doceava parte del tiempo que transcurre entre el orto y el ocaso y una hora nocturna desigual es una doceava parte del tiempo entre el ocaso y el orto.

NdT: del libro "Tablas Alfonsíes de Toledo" de José Chabás y Bernard R. Goldstein, pág. 220, Capítulo 28.

Las celdas en fondo celeste son mis correcciones al Incunable 1612.
