The books...were...picture books?
You keep making that absurd claim yet regardless of countless requests to show documented verification have failed to do so. Here are some quotes for you to ponder.
"by the 1st century AD certain neighbourhoods of Rome were known for their bookshops (tabernae librariae), which were found also in Western provincial cities such as Lugdunum (present-day Lyon, France). [Cavallo, "Between Volumen and Codex," p. 71; Marshall, "Library Resources and Creative Writing at Rome," p. 253, citing on the book trade in the provinces Pliny the Younger, Epistulae 9.11.2; Martial, Epigrams 7.88; Horace, Carmina 2.20.13f. and Ars Poetica 345; Ovid, Tristia 4.9.21 and 4.10.128; Pliny the Elder, Natural History 35.2.11; Sidonius, Epistulae 9.7.1.]
"Collectors amassed personal libraries," [Marshall, "Library Resources and Creative Writing at Rome," pp. 252–264]
"An individual benefactor might endow a community with a library: Pliny the Younger gave the city of Comum a library valued at 1 million sesterces, along with another 100,000 to maintain it." [ Pliny, Epistulae 1.8.2; CIL 5.5262 (= ILS 2927); Marshall, "Library Resources and Creative Writing at Rome," p. 255.]
Even in Paul's day he commended the Bereans who "searched the scriptures daily".
All that reading yet no one could read!
