I see what you are saying. I am glad Petronius was mentioned because
The Satyricon is a prime example of the unusual circumstances of the so-called primary sources of the Romans. By the way, the short version of the Satyricon I read is disgusting, but I wouldn’t let that serve as proof of “mass media”. Apart from an honest summary by Wikipedia admitting the book was found in the 17th century, they also disclose the subjective nature of dating
“The date of the Satyricon was controversial in 19th- and 20th-century scholarship, with dates proposed as varied as the 1st century BC and 3rd century AD.
[11] A consensus on this issue now exists. A date under
Nero (1st century AD) is indicated by the work's social background
[12] and in particular by references to named popular entertainers.
[13][14]
Evidence in the author's style and literary concerns also indicate that this was the period during which he was writing. Except where the Satyricon imitates colloquial language, as in the speeches of the freedmen at Trimalchio's dinner, its style corresponds with the literary prose of
the period. Eumolpus' poem on the Civil War and the remarks with which he prefaces it (118–124) are generally understood as a response to the
Pharsalia of the Neronian poet
Lucan.

The Etruscan and Sardinian languages seem to me like the prime candidates as the forerunner to Latin, more do to their proximity and antiquity. But, Etruscan is read right-to-left and overlaps with hebrew, as does ancient Greek. I don’t know what came first, but PaleoGreek, PaleoHebrew and Etruscan have many similarities, more than Each other than with Latin. There are several books on this overlap by Saul Levin and Yahuda, and one Out of print, evaluating Etruscan as a semitic language and contrasting it with Hebrew by
Sevini. Here is the rationale behind that claim:

paper briefly discusses some major similarities and differences between Latin and Etruscan. Of note, the greatest similarity not shared with another language in the region is the numbering system, characterised by “counting by subtraction” (eg. IV instead of IIII).
