The Turin Shroud (TS) is a linen cloth commonly associated with Jesus Christ, his crucifixion and burial. Several medical specialists have debated the injuries of the TS Man, nevertheless there are no detailed and quantitative data about the anatomy of the TS face. The purpose of this study was to analyse the cephalometric measurements of the face image of the TS. The TS face image was acquired by a picture and processed using a cephalometric software, Oris Ceph® (Up to date 2012). The image of the soft tissues was processed in order to obtain skeletal points and a cephalometric analysis of the soft and skeletal tissues was performed. Image processing of the TS face shows that the Man represented in it has undergone a maxillo-facial trauma, especially a left displacement of the mandible, probably due to temporo-mandibular joint lesions. This condition has not been described before, despite several studies on the subject. (Folia Morphol 2015; 74, 2: 212–218)

INTRODUCTION

Suggestive and majestic, the face of the Turin Shroud (TS) is a highly controversial subject of studies, evaluations and interpretations. The TS is known throughout the world for its religious and scientific significance. It is a linen cloth depicting the image of a crucified man. The Christian religious community associates the image of this man with that of Jesus Christ [6, 18].

Since 1902, a series of anatomic studies on the consistency of the image of the TS and the nature of the wounds on it were made by many scientist and scholars starting with Yves Delage at the Academy of Sciences in Paris [10].

Several medical issues on the TS have been debated with the help of different disciplines as traumatology and forensic medicine. However, no studies about the cephalometric measurements of the TS face are currently available.

These types of measurements are normally taken from lateral or frontal radiographs, which are 2-dimensional just as the frontal photographic image of the TS face.

In our study, we have drawn inspiration from the anthropology, using the reverse procedure of the forensic facial reconstructions. In that field, the measurements of the face under investigation for recognition and identification are made starting from the skeletal structure found [3, 15]. In this study, once the data related to the soft tissues of the face depicted on the TS were obtained, we were able to analyse the skeletal facial structure by evaluating the craniofacial features, the possible asymmetries and any trauma, such as the ones of the patients undergoing orthognatic surgery [1, 2, 9, 14].

The aim of this study was therefore to analyse the cephalometric measurements of the facial image of the TS.

MATERIALS AND METHODS

Acquisition of the image

The image used for our measurements is a 1931 photograph taken by Enrie (Fig. 1), much clearer in the black-and-white negative than in its natural sepia colour. The digital image resolution was 72 dpi and the image displayed a pixel size of 0.284 mm.

The image of the face showed the measure of the height of the TS face (from the brow line to the chin) which resulted 23.4 cm. We acquired and processed the TS face image using the cephalometric software Oris Ceph® (Up to date 2012).

We performed two analysis of the TS face image:

  1. 1. Cephalometric analysis of the soft tissues. We identified 34 anatomic cephalometric points. The most significant cephalometric points of the soft tissues are listed in Table 1.

  1. 2. Cephalometric analysis of the skeletal tissues. The image of the soft tissue was processed in order to obtain skeletal points on the basis of the posteroanterior Ricketts cephalometric analysis. This procedure was based on standardised interpretation and reconstruction of the skeletal features, validated by many authors [13, 17]. We identified 23 anatomic cephalometric points. The most significant cephalometric points of the skeletal tissues are listed in Table 1.

DISCUSSION

Cephalometric analysis of the soft tissues

Vertical height. Ideally, a face can be vertically divided in equal thirds by 4 horizontal lines that pass through cephalometric points known as hairline (corresponding to trichion), glabella, subnasal point and menton. The lower third of the face can be further divided into thirds with the stomion marking the inferior boundary of the upper third, and the lower lip and chin forming the lower two-thirds [7, 11, 12]. According to our results, the upper third of the TS face has a height of 46.05 mm, the middle third has a height of 80.19 mm and the lower third has a height of 54.34 mm. The height of the middle third is increased. In the TS face, the approaching of the tip of the nose to the upper lip forms a sort of “saddle nose”, which is comparable to a fracture of the nasal cartilage as a result of a blunt trauma, like reported in other studies [16, 18]. Moreover, the correct height of the lower third of the TS face suggests that the TS man, at the time of his death, had complete, at least to his first premolars, dentition.

Widths. Ideally, a face can be divided into vertical fifths, with each fifth corresponding to the width of 1 eye. According to our results, the width of the left eye of the face of the TS (34.93 mm) is very similar to the width of the right eye (32.64 mm) as well as the width of the nose (30.07 mm). We also found a correct relation between the zygomatic width (130.23 mm) and the goniac width (112.13 mm): the cheekbone should protrude more from the goniac angle and, in the TS face, the ratio is observed.

Symmetry. To assess the proportion and the balance of the facial shape, ideally the various subunits (ears, eyes, eyebrows, nose, and lips) are symmetric if compared to the midsagittal line.

In our results, we found the lines of the right eye and of the left eye oblique and divergent; in particular, the line of the right eye forms an angle of 171.19° with the horizontal line while the line of the left eye forms an angle of 6.83°.

Also the line of the lips is not horizontal. Throu-ghout the upper vermilion skin border, 2 paramedian elevations of the vermilion form the Cupid bow and 2 raised vertical columns of tissue form a midline depression called philtrum. We found a discrepancy between the height of the right and of the left paramedian elevations of the vermillion (FIL = –0.66 mm).

Cephalometric analysis of the skeletal tissues

Maxilla mandible symmetry. In a symmetric patient, the maxilla-mandible line (MML), that joints the maxilla to the mandible (from the anterior nasal spine to the menton) should coincide with the midsagittal line (0 ± 2°). In the TS face the MML forms an angle of 4.22° with the midsagittal line. This asymmetry may be caused by a shift of the mandible, by a mandibular asymmetry or by a dependency of one of the jaws.

The distance between the lower incisors’ median line (Li) and the MML is 0.16 mm. This value, within the normal range, indicates the 2 lines are both deviated in relation to midsagittal line.

Maxilla mandible relation. The fronto-facial line (from the zygomatic-orbital point to the antegoniac point) is identified by the ZR-GA line on the right and the ZL-AG line on the left. The distance between the fronto-facial line and the zygomatic point itself (JR and JL) indicates the position of the mandible to the maxilla, regarding a possible skeletal cross-bite. As the distance ZR-GA/JR is 10.88 mm while ZL-AG/JL is 7.63 mm, a deviation due to a shift of the mandible on the left side can be considered. These measurements are schematized in Figure 4.

Majorana_04.tif

Figure 4. Maxilla mandible relation (scheme).

Dento-skeletal relation

The distance (Maxd and Maxs) between the lower molars and the maxilla (JR-GA or JL-AG) is another indicator of possible cross-bites. The position of the lower molars was automatically determined by the software starting from the anatomic visible structures. We observed a major distance between the lower molars and the maxilla on the left, which confirms the left displacement of the mandible. On the left (Maxs = 10.76 mm) there is an increase of +2.76 mm when compared to the right (Maxd = 7.32 mm). This seems to confirm the skeletal cross-bite due to a shift of the mandible on the left side.

Postural symmetry

The angle between the fronto-facial line (ZR-GA and ZL-AG) and the line from the zygomatic point to the ante-goniac point (AZ-GA and ZA-AG) is an indicator of postural asymmetries. We found the right angle (18.41°) greater than the left one (17.87°). Even if the discrepancy (0.53°) is in the normal range, this data could confirm, along with the other findings, the shift of the mandible. These measurements are schematized in Figure 5.

Majorana_05.tif

Anatomic structures

If compared with standard ranges, the width of the nose is correct (30.68 mm) while the height of the nose (from the anterior nasal spine to ZL-ZR line) is increased (72.55 mm). This result confirms the “saddle nose” (Fig. 6). The facial, maxillar and mandibular widths are inside the standard value ranges.

Majorana_06.tif

Figure 6. Increase in the height of the nose (scheme).

The new data about the TS face pointed out by this study is the presence of a mandibular asymmetry. The aetiology of the facial asymmetry may include genetic or congenital malformations (e.g. hemifacial microsomia and unilateral clefts of the lip and palate), environmental factors (e.g. trauma and habits) and functional deviations (e.g. dental interferences) [5, 8]. A recent study indicated that the man represented in the TS suffered a undeniable violent blunt trauma to the neck, chest and shoulder from behind, causing neuromuscular damage and lesions of the entire brachial plexus [4]. Thus, considering the TS face as a polytraumatised face, we can assume that the displacement of the mandible — fairly too large to be structural — was caused by the trauma itself, i.e. temporo-mandibular joint lesions. Bevilacqua affirmed that all the evidence is in favour of the hypothesis that the TS Man is Jesus of Nazareth. Even the facial trauma highlighted by the present study is confirmed by the description of Jesus’s Passion. In fact, the facial trauma could be caused by a strike on the face which is often reported in the Gospels [Mattew 26:67 “Then they spit in his face and struck him with their fists. Others slapped him.” — John 18:22 “And when he had thus spoken, one of the officers which stood by struck Jesus with the palm of his hand.”].

CONCLUSIONS

To the authors’ knowledge, this is the first cephalometric analysis of the face of the TS. From our data, there are evidences that the face depicted on the TS underwent a maxillo-facial trauma, resulting in a fracture of the nasal septum and especially in a displacement of the mandible, probably caused by temporo-mandibular joint lesions.
