luz equinoccial 8
Bright phenomenon that occurs in some Romanesque churches in Spain in the spring and autumn equinoxes. Sunlight penetrates at a time determined by the windows and illuminates the temple somewhere. In the Church of Santa Marta de Tera at Zamora the sun comes through the oculus of the head toward the 8 solar time, and illuminates the capital located to the left of the apse, about 5 minutes. This fact occurs two days before and after the equinox.
