I have a problem with one sentence:
Filii divitum Romanorum ad litteris studendum in Graeciam iter faciebant.
Does it mean:
The sons of the rich Romans travelled to Greece?
and what does the part "ad litteris studendum" means?
To learn litterature?
what I don't get is why is there a preposition AD, which normally should go with accusative, and litteris is in dative or abblative...
