"Pope/bishop Zephyrinus" is a fake, he really matches emperor Septimius Severus.
* Zephyrinus: name Zephyrinus / Zepheniah. name related to Greek west(ern) wind god. * Severus: name Septimius Severus. [gens Septimia. built the Septizodium? "Severan Wall".] [Annexed Zabi?] "After consolidating his rule over the western provinces...." Visited Britain (in West). Was fluent in Greek. "With his rearguard safe, he moved to the East...."?
* Zephyrinus: "The pope is described ... as a simple man without education. This is evidently to be understood as meaning that Zephyrinus had not taken the higher studies...." * Septimius Severus: "Little else is known of the young Severus' education, but according to Cassius Dio the boy had been eager for more education than he had actually got."
* Zephyrinus: "They formed an independent heretical community at Rome which was ruled by another Theodotus, the Money Changer, and Asclepodotus." * Severus: [Annexed Thabudeos? "Thyatira" in 'Revelation' = Constantinople (Byzantium which Severus campaigned against)? Argentocoxos?] "Arcus Argentariorum dedicated by the money changers of Rome to the Severan family." "Pertinax's successor in Rome was Didius Julianus, who had bought the emperorship in an auction."
* Zephyrinus: "A refutation of Proclus in the form of a dialogue was written by a learned and rigidly orthodox Roman Christian named Caius...." * Severus: "Severus's maternal cousin was Praetorian prefect and consul Gaius Fulvius Plautianus. .... In 173, Severus' kinsman Gaius Septimius Severus was appointed proconsul of the Africa Province. The elder Severus chose his cousin as one of his two legati pro praetore." "... after 197 Severus fell heavily under the influence of his Praetorian Prefect, Gaius Fulvius Plautianus...." Succeeded as consul by Gaius Cassius?
* Zephyrinus: "Although not physically martyred, he is called a martyr for the suffering he endured." / "Although he was not physically martyred for the faith, his suffering – both mental and spiritual – during his pontificate have earned him the title of martyr." * Severus: "...for he actually was conveyed in a covered litter most of the way, on account of his infirmity.... .... Severus' campaign was cut short when he fell fatally ill." heavy Roman casualties in Caledonia? [And/or by inversion: executed Pertinax's murderers. exterminating Caledonians. executions of large number of Senators. Eusebius' description of Severus as persecutor of Christians. Persecutions occured during his reign including martyrs. "...the edict of persecution appeared which forbade conversion to Christianity under the severest penalties."] [&/or Antonine plague??]
* Zephyrinus: Hippolytus was his contemporary and "antipope" after him. * Severus: "... and served as a high priest to the local cult of the sun god Elagabal. Domna's older sister was Julia Maesa, later grandmother to the future emperors Elagabalus...." ["...he ordered the covering of the tomb of his fellow Carthaginian Hannibal with fine marble."?] Heliogabalus/Elagabalus was Baal/El-worshipping emperor not long after him.
* Zephyrinus: "Combated against the adoptionist heresies of the followers of Theodotus the Byzantium...." * Severus: "While campaigning against Byzantium he...."
* Zephyrinus: "pope/papa / bishop / [pontiffex]". + Wearing a Crown in a picture. "this holy pastor was the support and comfort of the distressed flock" * Severus: "... Severus was well disposed towards Christians, employed a Christian as his personal physician and had personally intervened to save several high-born Christians known to him...." [Aemilius Papinianus?] Deified by the senate. [Pontiffex Maximus.] + Was emperor.
* Zephyrinus: Natalis "... was persuaded by Asclepiodotus to become a bishop in their sect in exchange for a monthly stipend of 150 denarii." * Severus: "Additionally the annual wage for a soldier was raised from 300 to 500 denarii." "Upon his accession he decreased the silver purity of the denarius from 81.5% to 78.5%. .... Nevertheless, the following year he debased the denarius substantially because of rising military expenditures. The silver purity decreased from 78.5% to 64.5% — the silver weight dropping from 2.46 grams to 1.98 grams. In 196 he reduced the purity and silver weight of the denarius again, to 54% and 1.82 grams respectively."
