Final answer:
The art of the Roman Empire shows a blending of classicizing style and Christian influences, which challenges the idea of artistic decline. Notably, the detailed sarcophagus of Junius Bassus and advanced Roman paintings demonstrate sophisticated tastes and skills.
Step-by-step explanation:
The subject of the question pertains to the complexities within Roman art and its evolution over time, particularly how it reflects various cultural and political influences. The information provided addresses the perceived artistic decline during the reign of Emperor Constantine, by contrasting classical style with the emerging Christian sentiment in Roman society. One detail that supports the notion that variances in tastes rather than a decline in skill is demonstrated by the Amiternum Tomb and the sarcophagus of Junius Bassus. Despite being from an increasingly Christian society, a classicizing style was preferred. This is evident in the sophistication and detail of Roman paintings that used techniques such as atmospheric and linear perspective, and in Roman sculptures that incorporated both classical Greek influences and a distinctive Roman emotional expression.
