Introduction

Skeletal remains belonging to a very tall individualwere found in a small cemetery, dated back to theImperial Age, discovered south-east of Fidenae (about7 km north of Rome, Italy).The extraordinary long bones indicate a growth

disease which may be linked to different syndromesthat produce excessive growth in most growth parame-ters. The most common etiology of overgrowth diseaseis due to a dysfunction of the pituitary gland, causingoverproduction of the somatotrophic or growthhormone (hGH). High exposure to the hGH producesgigantism in youths prior to epiphyseal fusion andacromegaly in adults (Aufderheide & Rodrìguez-Martìn,1998; Ortner, 2003).Growth disorders can also be due to a deficit of

development of the sexual organs before puberty, as

in Eunuchoid Gigantism (eunuchs are castrated males);it is characterized by a disproportionate increase in thelength of the lower compared to the upper limbs(Aegerter & Kirkopatrick, 1975). Tall stature associatedwith male hypogonadism can also be due to Klinefelter’ssyndrome caused by a chromosomal defect (Aufderheide& Rodrìguez-Martìn, 1998). Growth disorders also de-pend on cerebral gigantism associated with the so-calledSotos syndrome, in which the circulating levels of hGHare normal; children who are affected present acceleratedgrowth during the first two or three years (Melo et al.,2002). Growth increase and tall stature can also be dueto Marfan’s syndrome, a genetic disease affecting theconnective tissue, causing overgrowth of the lower withrespect to the upper limbs, with very slim diaphyses(Goodman & Gorlin, 1983).The presence of giants, like the tremendous legend-

ary individuals – such as Goliath killed by David – hasoften been reported in the past by ancient scriptures,but the first medical description of this disorder, called‘acromegaly’, was made in 1886 by Pierre Marie, whomarked the beginning of the study on pituitary disease

(Marie, 1886; Sheaves, 1999). Therefore, the cause ofacromegaly and gigantism finally became known inthe early years of the 20th century. The interest ingiant individuals was widespread in circus shows anddisplays of giant skulls and skeletons first appeared in18th century museums, but we have no reports abouttheir presence in the Roman world during the ImperialAge. The only exception was the Emperor Maximinusthe Thrax (235–238AD), described by literary sourcesas a human mountain, and according to the image onhis coinage had an acromegalic head; therefore, hemay well have been a giant (Roberts, 1978).In palaeopathological literature gigantism has been

rarely documented: a Polish female skeleton probablyaffected by gigantism dating to 12th–13th centuriesAD was described by Gladykowska-Rzeczycka et al.(1998), and a probable case was reported in a FifthDynasty skeleton (2494–2345 BC) from Giza, Egypt(Mulhern, 2005). More common cases of acromegalywere described by Brauer (1991), Brothwell (1981),Hosovski (1991), Ortner (2003), and Charlier &Tsigonaki, 2011.Cases of gigantism are better known in modern

times such as the famous case of the Irish Mr. Byrne,who died in 1783, and other case reports on generallyfamous giants published in the early years of the 20thcentury, when the abnormal stature attracted theattention of the community and also of doctors (Fulton,1946; Bergland, 1965); exhaustive descriptions in themedical literature have been reported by de Herder(2009). Some skeletons of giants are exposed inmuseums,but the oldest died only 250 years ago (Aufderheide &Rodrìguez-Martìn, 1998). Modern and more recent casesof pituitary gigantism are reported in endocrinologicalliterature (Vogl et al., 1994; Gläsker et al., 2011; Danielet al., 2013).

Materials and methods

The skeletal remains examined in this research werefound in 1991 during archaeological excavations inthe modern large estate of ‘Torre Serpentana’, to theeast of the 5th mile of the Via Salaria (di Gennaro &Finocchietti, 2006). In Roman times, this area wasindirectly managed by Rome, through the Municipium(administrative centre of the Roman territorial organi-zation) of Fidenae, the site of which lies 1.3 km fromthe burial area; Roman Fidenae arose in the site of aprevious independent Latin city, then conquered byRome (di Gennaro, 2006), from which it was dividedby Anio (Aniene river).The small cemetery probably refers to a community

living and working on one of the hundreds of farms(villae) documented in this sector of the Roman ager(di Gennaro et al., 2005). A total of 31 tombs wereexcavated, and the skeletal remains of 28 individualswere recovered. A tomb (T.30) longer than the otherswas found (2.6m), and the skeletal remains appearedto be those of a very tall individual (Pantano et al.,2011). Tomb 30 belongs to a group of simple fossagraves (originally covered with pottery roof tiles) thatseems to have been prepared and used during the firsthalf of the 3rd century. The individual was buried insupine posture with the hands placed under his pelvis,with no funerary goods. The skeleton was completeand in good condition, but the skull was fragmented.Diagnosis of the sex was performed according to the

morphological characteristics of the skull and pelvis(Ferembach et al., 1980; Buikstra & Ubelaker, 1994).Age determination was based on dental wear, stage offusion of the cranial sutures, and stages of epiphysealclosure (Brothwell, 1981; Meindl & Lovejoy, 1985;Scheuer & Black, 2000; Canci & Minozzi, 2005); the

pubic symphysis and auricular surface phases in thepelvis were evaluated (Lovejoy et al., 1985; Burns, 1999).The mandibular and postcranial bones were mea-

sured and the bone length ratio was calculated follow-ing the classical methods described by Martin & Saller(1957). Stature reconstruction was performed usingthe anatomical method proposed by Fully (1956) andrevisited by Raxter et al. (2006, 2007), including theage term of 18 years, which is probably one of the bestestimates of living stature. This method is based on thesum of all the skeletal components of height, but, in in-dividual T.30, the skull was partially fragmented andsome vertebrae were missing. Stature reconstructionwas also based on regression equations applied to longbone lengths. There are different regression formulaeobtained from different skeletal samples, but we usedthe classical formulae of Trotter & Gleser (1958) forWhite samples, which according to Formicola (1993)fit better with individuals over 179 cm. Moreover, theapplication of this method permits a comparison withother samples.Osteometric data and stature for individual T.30 were

compared with the mean values obtained from different

Roman Imperial Age male samples (unpublished datafrom the anthropological archive of the Service ofAnthropology of the Special Superintendence toArchaeological Heritage of Rome). The z-score wasaimed at evaluating the distance between the sizes ofT.30 and averages of the normal population. Z-scorewas calculated as the difference between T.30 measure-ment and average of the comparison samples dividedby standard deviation (SD).Skeletal pathologies were recorded following macro-

scopic and X-ray examination.

Results

The skeletal remains were attributed to a young male.The age estimation methods produced incongruentresults: the cranial suture closure is consistent with anage range of 35–45 years, while dental wear suggestsa range of 20–30 years. Epiphyseal closure does notprovide consistent evidence of age at death becausethe pathology may have delayed the fusion(Aufderheide & Rodriguez-Martin, 1998; Melmed &

Kleinberg, 2011). Moreover, the stage of epiphysealclosures shows variability and scarce uniformity be-tween the left and right sides, as reported in Table 1,and is consistent with an age range of 16–20 years.The pubic symphysis and auricular surface phases arein agreement with an age range of 18–20 years.Although partially fragmented, the skull presents al-

most normal dimensions and morphology, but thethickness of the frontal and parietal bones is irregular,with very thin spots and thicker areas, in addition tothe frontal internal plate which shows a slight form ofhyperostosis frontalis interna. External auditory exostosis ispresent in the right acoustic canal, half-occluding theexternal meatus. The sphenoid bone is not conserved,owing to postmortem damage, but a fragment of thehypophyseal fossa of the sella turcica is fused with theoccipital bone. The pituitary area appears enlarged anddepressed; in fact, the normal size of anterioposteriordiameter for the sella turcica is 11.3� 1.1 (Axelsson et al.,

2004), while in individual T.30, the partial dimensionsare 16mm at the anteroposterior diameter and 17mmat the transversal axis, but could be larger and longer asthe bone is only partially conserved (Figure 1).The maxillary and mandibular bones are massive and

prominent with a teeth-to-teeth occlusion; the jaw haslarge mandibular condyles and is very wide and longwith a prominent chin (Figure 2).Large residual vascular channels are visible on the

anterior surfaces of the thoracic vertebrae, a conditionoften observed in infantile skeletons with strongvascularized bones, but not in youths like individualT.30. This suggests active bone stimulation by con-tinuing growth.The most evident anomaly is represented by the

large size of all the bones: the postcranial bones arevery long with regular morphology and withoutpronounced musculature (Figures 3, 4). The handsand feet present extremely long bones. X-rays show

that cortical thickness and long bone length wereaffected proportionally (Figure 5).The proximal epiphysis of the femurs shows a

change in head orientation: the head and the foveacapitis are vertically rotated (Figures 5, 6). The proximalepiphysis of the tibias is also tilted towards the midlineresulting in genu valgum with medial bowing of the legsat the knee level, with slight different inclination of thetibial plate between the two tibias which, associatedwith non-uniformity of the epiphyseal closure, pro-duced the difference of 10mm observed in their totallengths (Table 2).These anomalies probably reduced the mobility and

working abilities of this individual, in particular in thelower limbs, where the musculo-skeletal attachments ofthe muscle involved in walking show slight development,

and the slipped capital femoral epiphysis may havecaused loss of motion in the hip joint (Loder, 1998).The stature reconstruction resulted in 196.4 cm by

the anatomical method of Fully (1956), and 197.8 withthe Raxter et al. (2006, 2007) correction. These valuescan be increased by almost 3–4 cm as supplementarycorrection because many vertebral annular epiphyseswere unfused, as well as the distal epiphysis of the leftfemur. The stature was also calculated on the basis ofthe long limb bones by means of regression formulae(Trotter & Gleser, 1958, White formulae). Staturevalues ranged from 199.6 cm for the tibia to 205.9 forthe femur with an average value of 202.2 cm.Table 2 reports the skeletal measurements for

individual T.30, Table 3 reports selected comparativedata for male samples from other Roman Imperial Agenecropoles, and Table 4 shows the estimated statureby long bone lenghts. The average male Roman staturewas around 167 cm during the Imperial Age, and thedifference with T.30 is 35 cm (21% over the averagestature of the population), indicating an overgrowthsyndrome. Classic overgrowth disorders are those inwhich all or most of the parameters of growth andphysical development exceed 2 SD above average forthe person’s age and sex (Weaver, 1994). We can eval-uate this condition by means of the z-score tabulated inTable 3, where it is possible to verify that all the mainlong bone lengths are over 5 SD. The bone length ratioshows similar values between T.30 and the Romansample, indicating normal body proportions (Table 3).In conclusion, this individual exhibited a very tall but

normally proportioned stature due to an overgrowth dis-order; some long bones and vertebral bodies did not showcomplete epiphyseal union, and therefore the staturewould probably have been taller, if he had lived longer.

Discussion

The observed skeletal evidence is characteristic of agrowth disease which may be linked to different disor-ders. Differential diagnosis was performed taking intoaccount the overgrowth syndromes that produce ex-cessive growth in most growth parameters.In Eunhnuchoid Gigantism, puberty and epiphyseal

fusion are delayed, bones are long and tubular with lackof normal muscle development, and there is a dispro-portionate increase in the length of the lower com-pared to the upper limbs. This disease, as well ashypogonadism, induces bone loss in both cortical andtrabecular bone (Aegerter & Kirkpatrick, 1975; Chew,1991; Kung, 2003), anomalies not found in individual

T.30 in which X-rays showed normal trabecular massand thick cortical bone.Klinefelter’s syndrome can be associated with delayed

skeletal maturation, small skull dimensions, short meta-carpals, radio-ulnar synostosis, and accessory epiphyses(Kosowicz & Rzymski, 1975; McAlister, 1988), notpresent in individual T.30.Cerebral gigantism associated with the so-called

Sotos syndrome induces a rapid growth during the firstyears of life with significant increase in head circumfer-ence and delayed psychomotor development (Meloet al., 2002), while Marfan’s syndrome induces over-growth of the lower compared to the upper limbs.These characteristics were not found in this case study.Pituitary gigantism and acromegaly are the most

common etiology of overgrowth disorder, caused byoverproduction of the growth hormone (hGH), associ-ated with a dysfunction of the pituitary gland(Aufderheide & Rodrìguez-Martìn, 1998; Ortner, 2003).Gigantism is a very rare condition, in which the

hypersecretion of hGH onset before epiphyseal closurestimulates cartilaginous activity at the growth plate andaccelerates linear growth of normal body proportionsultimately resulting in very tall stature. Gonadotropinsuppression causing delayed epiphyseal fusion andpuberty disorders are also quite common (Aegerter &

Kirkopatrick, 1975; Aufderheide & Rodrìguez-Martìn,1998; Melmed & Kleinberg, 2011). Overproductionof the growth hormone (hGH) during adulthoodresults in acromegaly, a more common condition thangigantism, in which the continuing secretion of hGHafter epiphyseal fusion stimulates the growth of theremaining cartilage and periosteum, causing over-growth of the facial bones, mandible, ribs, sternum,intervertebral discs, and marked periosteal bone appo-sition. Hyperpituitarism is often caused by a pituitaryadenoma, a benign tumour that can provide stimulusfor the hypersecretion of the growth hormone,resulting in body overgrowth with normal proportions(Resnick, 1988; Aufderheide & Rodrìguez-Martìn, 1998;Ortner, 2003).The pathological features observed in individual

T.30 are more consistent with a pituitary disturbancethan any other syndromes resulting in skeletal over-growth. In this case, we cannot talk of acromegalybecause T.30 presents some unfused epiphysis (Table 1).Moreover, acromegaly induces periosteal apposition andbone overgrowth in the mandible, hands, and feet,which were not observed in this case (Resnick, 1988).The very long proportionate bones and the

nonuniformity or delayed epiphyseal closure combinedwith possible enlargement of the sella turcica agree with

hypophyseal abnormality onset during childhood,leading to a diagnosis of hyperpituitary gigantism.Other elements such as alteration of the frontal bone

and femur capitis support the diagnosis. Hyperostosisfrontalis interna is a condition in which there is thicken-ing of the internal table of the frontal bone and an as-sociation with pituitary gland disorders, acromegaly,toxic goiter, and diabetes has been reported in clinicalliterature (Fulton et al., 1990; Waldron, 2008). There-fore, endocrine diseases such as gigantism and acro-megaly can be associated with slipped femoral head,as observed in individual T.30 (Reeves et al., 1978;Feydy et al., 1997).

Conclusion

Differential diagnosis, performed considering otherovergrowth disorders, suggests that the most probableetiology of the pathological alterations observed isconsistent with pituitary gigantism. In particular, thepossible alteration of the hypophyseal fossa of the sellaturcica could be due to a pituitary adenoma that canproduce a dysfunction of the pituitary gland, causingoverproduction of the growth hormone (hGH).The life span of people affected by gigantism is not

high; in fact, several diseases may be associated withthis disorder such as chronic complications dominatedby cardiovascular and cerebrovascular diseases,

generally appear before age 30 years (Aufderheide &Rodrìguez-Martìn, 1998).Gigantism is a very rare disease (modern annual

incidence: 3/1,000,000), rarely documented in ancientskeletal remains (Mulhern, 2005), so we suppose thegreat height of the individual we have studied must havemade him a curiosity in Roman society. Unfortunately,we know nothing about the presence of giants in theRoman world and whether or not they were treateddifferently from others, but we know that during theImperial Age, the members of the high society devel-oped a pronounced taste for entertainers with evidentphysical malformations, such as hunchbacks and dwarfs.We presume that even a giant is likely to have arousedinterest and curiosity. However, the archaeological datarelated to the necropolis did not reveal any peculiardifference of the tomb of the giant, which belongs to agroup of simple fossa graves with no funerary goods.This case represents an extraordinary discovery for

the first time documenting gigantism in a completeancient skeleton, providing an important contributionto palaeopathological literature.
