Some authors have downplayed the importance of complex vaulted systems in ashlar in Roman architecture. This has led them to seek the origins of Early Modern stonecutting in Christian Syria or Languedocian Romanesque. However, some examples in many regions of the Empire, including Lazio, argue for the existence of advanced stonecutting techniques in the Roman world. In this paper, we will study an interesting example of these structures, the Grotta dei Massacci in Osteria Nuova, now in the municipality of Frasso Sabino. Starting with a precise survey carried out by 3D laser scanning and automated photogrammetry, we will put forward some hypotheses about its measurement system, proportion, stonecutting technique and the hoisting systems used in its execution.

Grotta dei Massacci 的罗马阿什拉腹股沟拱顶

一些作者淡化了罗马建筑方石中复杂拱形系统的重要性。这导致他们在基督教叙利亚或朗格多克罗马式中寻找早期现代石刻的起源。然而，包括拉齐奥在内的帝国许多地区的一些例子都认为罗马世界存在先进的石刻技术。在本文中，我们将研究这些结构的一个有趣例子，即现在位于 Frasso Sabino 市的 Osteria Nuova 的 Grotta dei Massacci。从通过 3D 激光扫描和自动摄影测量进行的精确测量开始，我们将对其测量系统、比例、石材切割技术和执行中使用的起重系统提出一些假设。
