Your remarks on the similarities between German and English in no way authorizes a contention that English derives from German. As for generalizing about socities, that is precisely what you have done and it is to that which i objected.
Rufio wrote:From what I remember learning about them, they liked to party, and build theaters, and liked to participate in spectator sports.
This is one of the most hilariously ill-informed comments i've ever read. Here's a short list for you:
Titus Livius,
Ad Urbe Condite, a history of Rome written in the Augustan age, in more than 130 "books" (four or five of these books make a slim paperback).
Suetonius,
The Twelve Caesars
Tacitus,
The History of Imperial Rome,
The Annals of Imperial Rome,
Germania,
Cerealis. The first two are fragmentary, but largely complete. The
Germania is the earliest description of these people available;
Cerealis is a life of his father-in-law, who governed Britain briefly, and who was the first to circumnavigate the island, of whom we have a record, at any event.
Polybius,
The Histories. This is an extremely important work. Polybius was a Greek, writing for the Greeks of the Amphictyonic League, to explain to them the people who had overwhelmed their world. Tacitus, Livius and Suetonius wrote for other Romans, and assumed a great deal (reasonably) about what their audience knew of their own history. Polybius was at pains to explain to his fellow countrymen what the Romans were all about, including their public institutions. A must read for anyone who would understand Rome.
Plutarch,
The Lives of the Noble Greeks and Romans. Just about the earliest attempt at coherent biography, Plutarch wrote biographical sketches of his subjects, which were necessarily short, as he seems to have confined himself to what he considered reliable information. Many of his biographical sketches are in the form of comparisons of one personality with another.
Let me know when you finish those, the list is a great deal longer than that. Those are primary sources, as well--i.e., the starting point for any historian.
