Sacred Journey Towards the Sun
Based on the provided quote from the text, it becomes clear that the term “posolon” is used to indicate a movement directed toward the sun. In the context of a religious rite involving crosses, it is emphasized that when sanctifying a church, the crosses should be carried specifically in that direction. In this way, the act is understood as a processional movement facing the luminary—the side on which the sun is present—which is most likely symbolically associated with the east (the beginning of a new day, light, and renewal).

“In support of their claim that during the consecration of a church, one should carry the crosses posolon, they, as the chronicler reports, having no other testimony, said the following: ‘The righteous Sun, Christ, trampled upon hell and bound death and liberated souls, and for that reason they depart on Easter, and similarly transform it at Matins.’ The dispute was left unresolved for a year or more due to the invasion in 1480 by Khan Akhmat of the Golden Horde.”
