Latin Literature
The Roman Empire lasted for more than a thousand years, so there was plenty of time to produce a lot of writing. Latin, an Indo-European language, was written in an alphabet derived from the Greek alphabet, with some letters changed: the Latin or Roman alphabet is essentially the one Americans use today. English-speakers have added the letters J and U and W.
Most of what was written during those thousand years
has been lost, but a fair amount still survives and we can read it today.
We like to think that the best writing has survived, but certainly some
very good works have been lost, while some of what survives is not very
good. Nearly all of the Latin literature that we still have today survives
because it was copied over and over by hand by different people through
hundreds of years. That is, almost none of the actual books that people
read at that time survive: papyrus
and parchment just don't
last that well. The words survive, but in later copies of later copies.
For some books, many copies survive; for other books, only one.
