Franklin & Marshall and Dickinson would be my picks for Ancient/World History, in probably that order. Both schools have some of the better course offerings in classics and archaeology among liberal arts colleges. Dickinson is also very good for international studies.
For Spanish and especially Arabic, that may be the case.
For Latin and Ancient History (and arguably World History as well), no. American offers neither Latin nor Greek, and its Ancient History offerings are virtually nonexistent.
The History and area studies programs at American focus almost exclusively on modern political history, and few classes touch on topics prior to the 19th/20th centuries. It lags behind virtually all of the other DC schools (Georgetown, GWU, CUA) in this regard.
