An historic sign, possible Mesolithic menhir, DStretch, and problems in dating rock art to the Sauveterrian in the Massif de Fontainebleau

This paper assesses the application of a consumer-grade unmanned aerial vehicle (UAV) solution for the imagebased three-dimensional (3D) reconstruction of a buried Medieval landscape at Monnikerede, a deserted former outport of Bruges, with the archaeological aim to achieve a better characterization of the (micro)topography and ultimately a better understanding of the site. The UAV survey resulted in a highly detailed and accurate 3D model of the terrain, allowing a thorough topographic analysis of the complex archaeological landscape. Application of algorithms to produce an enhanced visualization of the topographic variability led to a sequence of derivatives each highlighting the topography in a different way. Additionally a decorrelation stretch was applied on the collected imagery, thereby generating enhanced orthophotos producing another view on the archaeological landscape. Integrating the (enhanced) orthophoto(s) with the digital surface model (DSM) and derivatives to conduct a thorough analysis of the archaeological landscape resulted in the detection and identification of new archaeological features and the formulation of new insights in the layout of this important Medieval outport. ResultsDespite the slightly irregular flight pattern and flight altitude (both a result of the manual control of the UAV), we were able to generate a highly detailed 338 J. De Reu et al.

“…Menhir culture has been known since prehistoric times (Caldwell, 2014), and continues until the era of ethnography in various parts of the world. Etymologically the term menhir (in Toraja is called simbuang) comes from the Breton language, namely from the word "men" means stone and "hir" means to stand.…”

The Toraja ethnic community has a unique culture that was passed down from a predecessor generation and is still maintained today. One of the cultural uniqueness is the tradition of establishing a simbuang (menhir) in the implementation of ritual ceremonies, especially in the ceremony of the death of the nobility that is marked as the ritual ceremony. The question is what the role of the establishment of the simbuang in the procession of the death ceremony for the Toraja people. The research method was carried out using survey and interview techniques with ethnoarchaeological approach. The results of this study provide an explanation that the nature of the establishment of the simbuang at Rante during the rapasan ceremony is a sign for a deceased figure who will become a media of respect by his children and grandchildren and the relatives he left behind. When the ceremony of the ceremony is placed in a place of symbol (rante), the symbols that stand in the rante are considered as the embodiment of the ancestors who need to receive certain treatment such as respect, given offerings, a place to bind the buffalo symbolically to be offered, and even as a medium for worship of ancestors, as stipulated in the aluk to dolo belief.

“…Another enhancement treatment worth mentioning, is implemented in the very handy DStretch plugin developed by John Harman [17] and based on a decorrelation stretch algorithm [19,20]. This plugin was designed for rock art color enhancement of standard (reflection) photographs (see [21][22][23][24] for example), but has occasionally been applied to other materials, such as an Egyptian wall painting [25] and a Mesoamerican manuscript [26]. We show that it can be equally useful for the enhancement of medieval writings (or any other graphical contents) in UV fluorescence color photographs (Figure 10).…”
