It's my understanding that plagiarism was NOT considered a problem until recent times. Ancient authors freely used works by other authors long dead, wrote anonymously, and even wrote pseudonymously, using the names of ancient authors. Ideas and words used to be free, as in speech. Only recently did the idea of owning imaginary property come about.

Well, if first century is "recent times" to you, then yes. Till about then it was not a big problem since human settlements were small and people know each other well enough that it was impossible to pretend you are great philosopher using only works of others. As settlement grew problem become more and more acute but it become serious problem only after invention of printing press since that's when reader finally lost any hope of ever seeing the author end and when price of books went down so drastically that you needed to sell thousands of them to make a decent living.
