where I can find clip arts or simple pics related to (represent / express) latin language?

Answer 1

You can easily use regular clip art to express any of the case endings in Latin, although particular ablative of time and place usage may remain a bit vague. I think you will have a tough time with the verbs however, unless you stick to simple verb forms.
Most English speakers have a tough time understanding the concept of the pluperfect subjunctive.

Answer 2

Ecce Romani

Answer 3

I mean I dont really know but you might can go on ask.com and search the latin language (under pics of course) and u might find somethin I dunno tho
