What is the difference between
Ne mea dona tibi studio disperta fideli
Nec mea dona tibi studio disperta fideli
and is the latter version, which differs in the single letter 'c' only, wrong?
This is a line from a famous poem of Lucretius.
This line, together with the one immediately following it, appears as the epigraph of quite a few, and quite different, 18th- and 19th century texts.
The second version does appear in the epigraph, but more rarely than the first line, which of course suggests that the second version is less correct.
My Latin is sadly much too rusty to understand what the difference between the two versions is.
