Pseudosarcophagus slab with crosses in a colonnade

The decorated stone sarcophagus, a centerpiece of the niche tomb, had long been a standard in Early Christian as well as pagan burial in the Mediterranean world. This tradition was continued in medieval Byzantium, although increasingly the body of the deceased was laid to rest below the church paving. The decorated sarcophagus—without a corpse inside it—was maintained as a symbol of the body's presence nearby, and connected this tradition with the earliest Christian burials. Sarcophagi were decorated with a wide range of motifs in relief carving, including intricate floral and vegetal forms, geometric patterns, sacred narratives, and inscriptions naming the deceased.这件作为壁龛式墓室核心陈设的装饰性石棺（sarcophagus），长期以来皆是地中海地区早期基督教与异教丧葬传统中的标准形制。这一丧葬传统在中世纪拜占庭时期得以延续，尽管彼时逝者的遗体日渐被安葬于教堂铺地之下。这类内部未安放遗体的装饰性石棺，仍被保留以作为逝者遗体就近安葬的象征，同时将该传统与最早的基督教丧葬习俗建立了关联。石棺多采用浅浮雕工艺装饰丰富的题材，涵盖繁复精美的花卉植物纹样、几何图案、宗教叙事场景，以及镌刻逝者姓名的铭文。
