In my journal on "16 Saviors Who Were Cruciied for Humanity", this is a folllow-up.
There were several of the 16 Saviors who experienced resurrection from the dead at about the time o the vernal equinox.
Those demigod Saviors who rose from the dead after 3 days burial, and the time of their resurrection is in several cases fixed for the 15th of March [it was also later, the same date for the resurrection of Jesus] are:
Quexalcote of Mexico, Chris of Chaldea, Quirinus of Rome, Prometheus of Caucasus, Osiris of Egypt, Atys of Phrygiu, and Mithru the Mediator of Persia are the only ones out of the 16 who DID rise from the dead. The others didn't make it!
