Abstract

During the excavations carried out in summer 2011 in Piazza Anita Garibaldi in Ravenna, during construction of the new underground waste containers, five rooms decorated with mosaic floors were found, probably dating back to the early Roman Empire (1st-2ndcentury AD). The mosaics were removed for restoration and musealisation, however –given the size of the large lacunae-it would not be possible to reintegrate them in a traditional restoration without creating arbitrary reconstructions. Therefore, we opted for a digital reconstruction of the lacunae, attempting virtual restoration hypotheses for the recovered mosaics. Subsequently, it was possible to grasp the trend of the figuration and how it could have appeared in the past. The characteristics of many mosaics, such as the symmetry and the repetition of geometric patterns, make them suitable for both a simulated integration and are construction by the analogies of the pattern. As a matter of fact, we used simple and easily accessible software to perform this work. The purpose of this digital workflow was to give an example of virtual processing useful for conservators and restorers, as well as for scholars (archaeologists, art historians, etc.) that can be carried out without specific information technology expertise and computer skills. After the images were acquired digitally, we were able to proceed with the reconstruction of the floor, by taking into account the geometric motifs that make up the mosaic assembly and that made the recomposition the most reliable. The virtual restoration also provides the opportunity of simulating the type of integration and the colour so that scholars, restorers and conservators may evaluate the final appearance of the work and the different aesthetic choices. The virtual restoration is finally considered an essential tool for the enhancement of cultural heritage.Highlights:An example of virtual restoration is presented relevant to Roman mosaics recently found in Ravenna (Italy).A simulated integration by the analogies of the geometric patterns present in the mosaics allows a reliable reconstruction.Virtual restoration results in a useful tool for enhancement, knowledge and improvement of understanding of mosaics by the general public.

意大利拉文纳城出土罗马马赛克的非度量数字重建

2011年夏天，在拉文纳的阿尼塔·加里波第广场进行的挖掘中，在建造新的地下垃圾箱时，发现了五个装饰有马赛克地板的房间，可能可以追溯到罗马帝国早期（公元1世纪至2世纪）。然而，为了修复和博物馆化，马赛克被移除了——考虑到巨大的缺口的大小，如果不进行任意的重建，就不可能将其重新融入传统的修复中。因此，我们选择了对缺口进行数字重建，尝试对恢复的马赛克进行虚拟修复假设。随后，我们可以掌握这种造型的趋势，以及它在过去是如何出现的。许多马赛克的特征，如几何图案的对称性和重复性，使它们既适合模拟集成，也适合通过图案的类比来构建。事实上，我们使用了简单易用的软件来完成这项工作。这种数字工作流程的目的是提供一个虚拟处理的例子，对保护人和修复人以及学者（考古学家、艺术史学家等）来说都很有用，而这些虚拟处理可以在没有特定信息技术专业知识和计算机技能的情况下进行。在以数字方式获取图像后，我们能够继续重建地板，通过考虑构成马赛克组件的几何图案，并使重新组合最可靠。虚拟修复还提供了模拟融合类型和颜色的机会，以便学者、修复师和保护人员可以评估作品的最终外观和不同的美学选择。虚拟修复最终被认为是加强文化遗产的重要工具。亮点：虚拟修复的一个例子与最近在拉文纳（意大利）发现的罗马马赛克有关。通过模拟马赛克中的几何图案进行模拟整合，可以进行可靠的重建。虚拟修复为增强、了解和提高公众对马赛克的理解提供了一种有用的工具。

期刊介绍： Virtual Archaeology Review (VAR) aims the publication of original papers, interdisciplinary reviews and essays on the new discipline of virtual archaeology, which is continuously evolving and currently on its way to achieve scientific consolidation. In fact, Virtual Archaeology deals with the digital representation of historical heritage objects, buildings and landscapes through 3D acquisition, digital recording and interactive and immersive tools for analysis, interpretation, dissemination and communication purposes by means of multidimensional geometric properties and visual computational modelling. VAR will publish full-length original papers which reflect both current research and practice throughout the world, in order to contribute to the advancement of the new field of virtual archaeology, ranging from new ways of digital recording and documentation, advanced reconstruction and 3D modelling up to cyber-archaeology, virtual exhibitions and serious gaming. Thus acceptable material may emerge from interesting applications as well as from original developments or research. OBJECTIVES: - OFFER researchers working in the field of virtual archaeology and cultural heritage an appropriate editorial frame to publish state-of-the-art research works, as well as theoretical and methodological contributions. - GATHER virtual archaeology progresses achieved as a new international scientific discipline. - ENCOURAGE the publication of the latest, state-of-the-art, significant research and meaningful applications in the field of virtual archaeology. - ENHANCE international connections in the field of virtual archaeology and cultural heritage.
