1) Does "Scoffers at history" mean "The people who scoff at Greek history"?
Read the whole sentence. The scoffers are those who say that to study history is to merely learn about "the gossip of dead people"; and are implied, I imagine, to be ignorant dicks, like those who call literature the study of dead poets, dead carrying a strong implication of irrelevant obsolescence.
