Summary
[edit]DescriptionTablas Alfonsíes - Lignères (1322) - P054.png |
Español: Traducción desde las tablas del año 1322 (Tablas de Alfonso), obra de Juan de Lignères. Agregüé unas columnas en el actual sistema decimal correspondiente al sistema sexagesimal ptolemaico. La primera columna es para el argumento, de 1° a 90°, a intervalos de 1°. Las entradas corresponden a la declinación solar y se muestran en tres columnas, cada una de 30°, en grados, minutos y segundos. La entrada máxima, 23;33,30°, es la oblicuidad de la eclíptica y ocurre en el argumento 90°. La misma tabla, con el mismo valor para la oblicuidad, ya se encuentra en las Tablas Toledanas (Pedersen 2002, p. 964). Esta tabla se menciona en el capítulo 11 en los cánones que comienzan con Cuiuslibet arcus (ver Saby 1987, págs. 101-103), donde el valor máximo, 23;33,30°, se da explícitamente y en el capítulo 19 en los cánones que comienzan con Priores astrologi (ver Saby 1987, p.205). NdT: del libro "The Tables of 1322 by John of Lignères. An Edition with Commentary" de José Chabás y Marie-Madeleine Saby. Págs. 54-57. 2022, Brepols Publishers n.v., Turnhout, Belgium. La celda en fondo color celeste es mi corrección a este último libro. |
