Here is an interesting article on possibly pushing back the date of the redaction of the bible and the extent of literacy at the time and in the culture.
The article misses some serious problems with literature and literacy prior to the common era. It just so happens almost no culture wrote their religious books down prior to 65BCE. Then around 65BCE it all got written in a storm.
What was going on in 65BCE was the Persian Emperor, who had conquered India, set up scriptoriums to set down in print much of the religious literature of the day, including the Pali Canon and the Bible.
My interpretation of this even, as an anthropologist who has studied ancient literature extensively, is prior to the redaction of religious literature, the priesthood of each religion had control of religious literature through memorization. This meant anyone who wanted to understand the teachings of the ancient sages, mystics, and prophets of the past had to go to a priest to do so, which more often than not came with a donation.
This means control of the religion's literature was a livelihood for the priests, and a source of power. This means, when King Malinda (Minander) had the religious literature written down, he took power from the priesthood and took it for himself, and gave it freely to the population who were interested in literacy.
Now, how common was literacy? Books needed to be printed for access to literature, which required Gutenberg to invent the printing press in 1439. Literacy; however, was not common in any culture until the 19th century. Now literacy is so common that we almost never meet someone who is illiterate.
So, in my opinion, the article has a number of problems with its basic premises.
The Bible was written way earlier than we thought, mathematicians suggestEven if you’re not religious, there’s no denying the enormous - and sometimes devastating - influence that the Bible as an historic text has had on the world over the past 3,000 years. And yet, when it comes to the most widely distributed book on the planet, we still can’t agree on who wrote it, and when.
So a bunch of mathematicians teamed up with archaeologists to shed a bit of light on the origins of the Bible, by using artificial intelligence to come up with an estimate of how many people could read and write during certain periods in ancient history.
Led by mathematician Shira Faigenbaum-Golovin from Tel Aviv University in Israel, the team came up with new image processing techniques and a handwriting recognition tool to investigate 16 inscriptions found in the desert fortress of Arad, just west of the Dead Sea.
Dated to around 600 BCE (so about 2,600 years ago) these ink inscriptions detail fairly mundane military commands and supply orders, and were written on ceramic pottery shards called ostraca during the late First Temple Period - 24 years before the Kingdom of Jerusalem was overthrown by the Babylonian king.
