The latin words templum, fanum, delubrum and aedes are all applied to a temple, a shrine or a sacred place. Even if, in some cases, their meaning may be similar, these words are not equivalent. In the Roman palliata, they are used in a specific way, which is different from the common use in Latin. Templum is commonly used in latin litterature, but scarcely occurs in Roman comedy where, on the contrary, fanum and aedes are rather frequent. Delubrum is almost never used in Plautus’ and Terence’s theater. The presence of dramatic conventions, the use of the « double énonciation » (double saying) in performance and of Roman realia mixed with Greek models (especially in Plautus), can explain these characteristics. The evocation of temples in the text and their presence on the stage trains and improves the audience’s imagination. In Plautus’ comedies, men and gods live in a neighbourly way ; houses and temples are in close proximity to one other, and have complementary functions. In Terence’s comedies, temples are rarely mentioned and, strikingly, do not appear on the stage. Links between men and gods are not important for the writing of the plot. The playwright prefers to deal with the subject of human relations and of souls’ complexity. This does not prove any social or religious pessimism on his part, as it was said.
