News about the solar effect in the church of San Juan del Hospital
Again we bring as news a solar effect in the church of San Juan del Hospital. But some variations have surprised us.
Last Wednesday 24 June, saint john's day, this solar effect as a "flower of light", was projected completely vertically almost on the front of a bench (perhaps it would be projected like this in the bottom of the primitive ship).
Why are these effects? How to follow and anticipate your movement?
Let's see, the problem of dates.
From 1582, sustituyó gradualmente al calendario juliano, que Julio César instauró en el año 46 to. C.
The Julian calendar was, basically, el calendario egipcio, primer calendario solar conocido que estableció la duración del año en 365,25 days.
En las Tablas alfonsíes, realizadas por iniciativa de Alfonso X de Castilla, a tropic year has already been assigned a value of 365 days 5 hours 49 minutes and 16 himself. Pending corrections.
El calendario gregoriano fue un primer estudio realizado en 1515 por científicos de la Universidad de Salamanca, seguido de un segundo en 1578. Although the merit was attributed to other astronomers: Cristóbal Clavio y Luis Lilio.
Pedro Chacon, Spanish mathematician, fue el que redactó el Compendium, con el dictamen de Lilio, supported by Clavio, aprobándose la reforma el 14 September of 1580, para llevarla a la práctica en octubre de 1582.
In this way, Thursday 4 October of 1582, according to juliano, fue sucedido por el viernes 15 October of 1582, Gregorian calendar. Thus adjusting the true solar year with 11 days less.
El efecto luminoso que se produce en la nave de San Juan del Hospital, whose warheads were built at the end of the s. XIII, also undergoes this calendar gap.
The current solstice day, the light projection was not fully appreciated and we will have to wait to see it on the corresponding date of the Julian calendar. More or less will be the 7 u 8 July current. We will see what happens that day ....
For this, Rector D will be pending. Carlos Cremades and the architect Adolfo Alonso. In collaboration with experts on the subject such as Professor Kim Lloveras and Francès Llop.
Adolfo Alonso Durá that we can see it in the images, was taking action, He worked on the restoration of the Royal Chapel of Santa Barbara thanks to the "Raphael Project" of the European Commission for Culture for the Diffusion of European Heritage as well as the Project to demolish the old printing press workshop to allow the carrying out of archaeological excavations in the basement of the old hospital cemetery and in the crypt of Empress Constance.
