roman concrete was lost during the christian period and there was significant lag in infrastructural upkeep in europe for several centuries after
>art
art also took a serious nosedive during the christian period, just look at early byzantine art. art would not achieve the same level as the romans until the renaissance and most of that was pagan influenced; even the purely christian art in subject matter took inspiration from the old roman works
>engineering
several engineering and technological marvels of the greco-roman world were lost during the christian period
>literature
highly subjective. Metamorphoses by Ovid and the Iliad by Homer are still considered masters of western literature, from whom a thousand other masters took their inspirations. Paradise Lost is a wonderful work of literature but even Milton opens the poem with a dedication to the Muses; pagan goddesses of inspiration reimagined as christian angels or spirits in the poem, and the entire structure of the poem is clearly inspired by the epic poems of the pagans. Dante used similar inspirations from roman mythology to construct his divine comedy
