Coptic Anno Martyrum, Diocletian and Basilica Santa Maria Maggiore
Coptic years are counted from 284 CE, the year Diocletian became Roman Emperor, whose reign was marked by torture and mass executions, especially in Egypt. Hence, the Coptic year is identified by the abbreviation A.M. (for Anno Martyrum or "in the Year of the Martyrs").
Coptic from KA PTAH, the energy of Ptah (Lucifer, Freyr, Deus/DIO/Zeus, Set, Khafre, Ptolemy XIII, etc etc).
DIO Christianus > Diocletian
Etymology: The French word crétin is derived from the Alpine dialectal crestin, which in turn stems from the Vulgar Latin christiānus ("Christian" or "poor fellow").
The "Christian" Connection: The term was originally used as a form of pity, implying that a person with such a disability was "a poor Christian" or "Christ-like" .
