The director of EDICES, Prof. Alfonso Sánchez Hermosilla sends us a communication in which he explains how and why the work grids have been reworked in both the Soudarion and the Síndone. At EDICES we continue researching and advancing in the knowledge of both fabrics.
Re-elaboration of the Oviedo Soudarion and Turin Shroud of Turin Grids
1. Justification
The scientific study of the Soudarion of Oviedo (SO) and the Shroud of Turin (ST) have been the subject of great interest and debate in the scientific community for decades. However, despite advances in various disciplines, such as forensic medicine, history, archaeology, chemistry, physics, biology and mathematics, significant methodological deficits persist in the investigation of these objects of great scientific importance.
One of these significant methodological deficits is graphics. Visual representation of data and results in OS and TS research has traditionally been limited and has not taken full advantage of modern visualization tools and techniques. This has made it difficult to understand and interpret the reported analyses, especially for non-experts in the field. The lack of clear and accurate graphical representations has prevented the identification of patterns and relationships that could be key to understanding the nature and origin of the characteristics of these fabrics.
By using advanced visualization techniques, this study seeks to set a referential context to improve communication between researchers and facilitate comparison and integration of results. In addition, by providing a more accurate and detailed graphical representation of the data, it may help to reveal new relationships and patterns that could have significant implications for the understanding of these archaeological objects.
Therefore, this paper presents the graphic reworking of the Oviedo Soudarion (SO) and the Turin Shroud (ST).
The following criteria have been used for the distribution of the grids:
1. A reference system is taken where the abscissa axis (X) follows an alphanumeric scale composed of a number and a letter, in that order. The number represents the grid number in increasing order from left to right of the images, and the letter indicates the part of the canvas ("r" reverse and "a" obverse in SO and "r" reverse and "f" - the original nomenclature of Flury-Lemberg, M. (2003) - obverse in ST has been preserved).
2. The coordinate axis is named with an alphabetical code, ordered in increasing order from the top to the bottom of the images. Once the entire alphabet is covered (excluding the letter ñ), i.e. up to Z, the letters are doubled and the code becomes two characters long (AA, BB and CC).
3. All the images have been covered with their respective grids, although this has meant that some cells have been left blank, that is, without an image. This confection has been necessary to save the irregularity in the perimeter of both canvases.
4. The grid has been compiled from high-resolution scans held by EDICES of both fabrics:
a. For the OS, the in-house scans obtained by the various scans of the canvas by our research team.
b. For the TS, the scanner donated by CISS (Centro Internazionale di Studi sulla Sindone) for research purposes.
5. Both the back and front of the SO have been gridded, divided into grids of 2 cm on each side, and for the ST of 4 cm on each side.
6. The different dimensions of the grid in the two canvases are explained by the difference in size between the canvases and the density of information in various areas of the OS, reasons why the reduction of the grid was considered necessary.
The grids are as follows:
1. Obverse of the Soudarion of Oviedo (Figure 1).
It is divided into 1204 grids:
· Horizontally in 43 grids ranging from 1r to 43r.
· Vertically in 28 grids ranging from A to BB.
Figure 1. Obverse Soudarion of Oviedo.
2. Reverse of the Soudarion of Oviedo (Figure 2).
It is divided into 1204 grids:
· Horizontally in 43 grids ranging from the 1st to the 43rd.
· Vertically in 28 grid squares ranging from A to BB.
Figure 2. Reverse Soudarion of Oviedo.
1. Obverse of the Shroud of Turin (Figure 3).
It is divided into 3219 grids:
· Horizontally in 111 grids ranging from 1r to 111r.
· Vertically in 29 grid squares ranging from A to CC.

2. Reverse of the Shroud of Turin (Figure 4).
It is divided into 3219 grids:
· Horizontally in 111 grids ranging from 1f to 111f.
· Vertically in 29 grids ranging from A to CC.
