This is reply to The Liturist post 275 (and Root of Jesse post 271).
The ebook when I last looked at it again I noted it was terribly written and hard for people to understand, and the ebook is down for rewriting now anyway so there is no need to worry about it or for me to give it. Also since you said you wanted to strongly complain to the publisher it seems unfair because if a person discovers something they believe to be true with evidences then it is unfair if they are barred from being able to publish it, because truths would never get out if they are barred from publishing. However I could post the some (more) evidences for the first 16 popes and you could try write a formal rebuttal ("perhaps with [our] help") as you said. Though i am pretty convinced from the quantity and quality of matches evidences. (There are even more matches between each pope and emperor than just the few ones i gave in the previous post.) I'll post each of the 16 popes below with some more of the matches (though still leaving out some). Or if you let me know if you/they don't want me to post all 16 here and I could post them in the history forum likned in my signature and then you can write your rebuttal from reading them there. I've written 5 of the 16 so far. I will cover the criticisms in posts 271 & 275 in the relevant pope posts. Below is the one on Pius 1 with a few more details than I previously gave.
10th Pope Pius 1
&
Emperor Antoninus Pius.
Both are named Pius.
(The meaning of the name Pius "religious, pious/piety, dutiful, holy, honest" might also match emperor Antoninus Pius?
"Antoninus acquired the cognomen Pius after his accession to the throne, either because he compelled the Senate to deify his adoptive father, or because he had saved senators sentenced to death by Hadrian in his later years." "One of his first acts as Emperor was to persuade the Senate to grant divine honours to Hadrian, which they had at first refused; his efforts to persuade the Senate to grant these honours is the most likely reason given for his title of Pius (dutiful in affection; compare pietas). Two other reasons for this title are that he would support his aged father-in-law with his hand at Senate meetings, and that he had saved those men that Hadrian, during his period of ill-health, had condemned to death."
"Antoninus was known as an avid observer of rites of religion....")
("like the similar error "Anicetus, Pius" for "Pius Anicetus"". Anicetus Pius similar to Antoninus Pius?)
Dates match:
Pope Pius 1 reigned 140/142/146-154/155/157/161 (compiled from six different official popes lists) "during the [reign] of Antoninus Pius".
Emperor Antoninus Pius reigned 138-148-156-161 (and his successor Marcus Aurelius took some role from 156.)
Both dates coincide 140-155/161 (the whole of pope Pius' reign),
both almost the same start date 138/140, or similar date 146/148;
both the same date 155/156/157,
both the same end date 161.
The argument that Pius "reposed in 155 AD, ... he predeceased Emperor Antoninus Pius by six years" is not valid because (1) the end date for Pius is 154/155/157/161 in different sources, and (2) the end date "155" probably relates to that Marcus Aurelius took some role from 156.
Both are pontiffex maximus.
Pius 1 is bishop / "pope" / "pontiffex maximus" / "supreme pontiff" (Annuario Pontificio, Liber Pontificalis).
"the account of his [Justin's] martyrdom indicates there was no Roman bishop present there."
Antoninus Pius was pontiffex maximus (the emperors from Augustus to Gratian were pontiffex maximus).
"Antoninus was known as an avid observer of rites of religion...."
[The argument that the titles pontiffex maximus and pope were not used by/for bishops of Rome until later (mid-5th & mid-6th centuries) and so is an anachronism is not necessarily valid because bishop/pope/pontiff are still related.]
Both are in Rome.
With both the popes & emperors before and after also match each other all in order.
1 Peter (Nero) = Nero (Peter)
2 Linus = Vespasian
3 Cletus = Titus
4 Clement 1 = Domitian (Clemens)
5 Evaristus = Nerva
6 Alexander 1 = Trajan (Alexander)
7 Sixtus 1 = Trajan? or Hadrian?
8 Telesphorus = Hadrian?
9 Hyginus (Graecvs) = Hadrianus (Graeculus)
10 Pius 1 = Antoninus Pius
etc.
See each separate pope & emperor chapter for matches details.
Both died aged 74:
Pope Pius aged "74" at end of his papacy (ref Wiki).
Emperor Antoninus Pius aged 74 at end of his reign.
Both are associated with the 10/11th of July:
Pius 1's feast day 11 July.
Antoninus Pius accession day 10/11th of July.
Both are linked with freed slaves:
Pius: "The writer of the later text identifies himself as a former slave. This has led to speculation that both Hermas and Pius were freedmen."
Antoninus Pius: "Antoninus passed measures to facilitate the enfranchisement of slaves. Mostly, he favoured the principle of favor libertatis, giving the putative freedman the benefit of the doubt when the claim to freedom was not clearcut."
Pope Pius 1 built 1/2 churches & baptistry.
He "built a concealed church on the second floor of a bath house which had been converted to a residence. This church, Santa Pudenziana, is the oldest surviving church in Rome...."
Antoninus Pius authorised the construction of a temple to Faustina.
"Antoninus built temples, theaters, and mausoleums...."
["newly built temple to Hadrian"?]
Pius "Martyr (by sword)". But they otherwise say it was a conjecture and is no grounds for consideration, and he is not presented as martyr in 'Roman Martyrdom'.
There is no contemporary proof that any pope Pius 1 ever existed. "Many popes in the first three centuries of the Christian era are obscure figures". "the account of his [Justin's] martyrdom indicates there was no Roman bishop present there."
"The actions of Pius I are recorded in multiple second and third century sources." But what are the details, and how reliable really are these sources even to a secular academic historian? Do they say he was bishop? They might have even begun the pope/emperor correspondences as early as then.
"Additionally, he (Pius) also left us archaeological evidence as to his existence, for he built a concealed church...." But there is no contemporary inscription of name of bishop Pius in/on the church?
"Hermas the brother of Pius wrote The Shepherd of Hermas which work is dated to the mid-2nd century". But does that work mention a bishop Pius?
