From Turkey round to North Africa very large quantities of spolia sources have survived, simply because population pressure has destroyed most comparable complexes in the West (compare Douai in 1391, where 95% of the stone appears to have been in reuse, with the systematic purchase of old properties for demolition.) Hence streets of tombs of which the Via Appia now provides such scarce remains are better envisaged from Elaiussa Sebaste, Hierapolis, or Assos in Turkey. In a sense, we can visit such areas today and imagine when we view the large range of surviving ancient monuments that we are actually transported into mediaeval Europe, and confronting ancient monuments there. In spite of depradations and some extremely serious earthquakes, large quantities of antiquities remain; some antique sites have only recently stopped being inhabited; and the population pressures that were such a devastating feature of later mediaeval Europe are largely non-existent, so that antique sites, except those by the sea, are probably safe for the future.
The re-use of spolia may be observed all over the ex-Greek or ex-Roman world, often by peoples who have no genetic or apparently cultural connection with Greece or Rome, but who affected the antique taste for extravagant materials such as marble, without necessarily wishing to quarry their own. This practice seems most frequently to be taken for granted, and we may suspect the re-use of spolia as totems of Roman grandeur, tradition, or architectural splendour – a usage arguably parallel to that of nouveaux-riches who acquire old portraits for their houses in order to give themselves a pedigree. In the case of fortifications, the ideological justification is an old one, because the equation between walls equalling civilisation, and no walls equalling either barbarism or subjection, goes back to the Greeks. Spolia walls, with the enormous effort needed to construct them, display continuity; but contemporary accounts are as lacking in the East as they are in the West, so we have no mediaeval rationale proffered to confirm this.
The richer the spolia, the greater the impact and influence: Crusaders and Armenians imitated classical building techniques in many of their castles, and employed antiquities frequently; the Seljuk Turks did likewise; the Ottoman Turks denuded classical sites for their own vast building works; and the French relied heavily on Roman roads and fortresses, as well as on Roman water systems and cisterns, for their conquest of Algeria. In other words, the French probably made use of antiquities in the same practical fashion that must have informed most of the Western Middle Ages, when Roman water supplies were convenient for baptisteries.
In the West documents, luckily, provide some kind of counterbalance to the lack of physical remains, but usually only by inference: explicit references to spolia are rare, although occasionally archaeology can help, as at San Vincenzo al Volturno. In the East, scholarly attention will not yet allow the production of the level of facts and figures, graphs and charts that may be found, for example, in Randsborg’s work for the West. In Greece, the beginnings of a corpus of mediaeval towers is appearing, fighting against scholarly disinterest. In Turkey, Syria and North Africa, Foss, Pringle and others are charting the landscape of mediaeval fortifications, and establishing a chronology.
Spolia are plentiful in Turkey and North Africa because in both areas invasions took over a country whose population had dropped dramatically since the hey-day of Roman occupation, and because of the fact that the invaders were without any tradition of their own of monumental architecture. Consequently, they continued at least some of the traditions of those they had conquered, including a respect for classical materials, which they also re-used in enormous quantities. For example, the 500-plus antique columns in the Great Mosque at Kairouan were famous, with some particularly admired for their sheer beauty by Leo Africanus, no doubt partly because the aesthetics imposed on the spolia with symmetry of forms and colours. El-Bekri, amongst others, remarks on the deux colonnes rouges, tachetées de jaune, dont la beauté est incomparable in the mihrab of the mosque at Kairouan, which he says came from an old church, that L'on raconte qu'avant le déplacement de ces colonnes, le souverain de Constantinople avait voulu les acheter au poids de l'or, aussi les musulmans s'empressèrent de les transporter à la mosquée. It has even been suggested that the Arabs bothered to cut but a few columns until well after Seljuk times, preferring to use spolia instead.  Certainly, foreigners were frequently impressed by their use of marble, and descriptions of sumptuous marble-rich palaces and baths abound, together with wonder at the quality of the marbles used, their whiteness and their smoothness. Even Christian churches as far east as Diyarbakir were rich in marble, and some of this survived past mediaeval times. But then, some people were clearly obsessed by marble, sometimes mistaking limestone for it.
In North Africa, such large quantities of spolia were available at least in part because of the spolia walls built during the Justinianic conquests of AD 533/554, and because of that same an acceleration of the processes of decay in once-populous cities that we find in Italy. Such walls arguably represented a renovatio for North Africa, although there are good reasons for treating such statements in inscriptions with some scepticism, the more so since dedicatory inscriptions (not to mention Procopius) do not mention spolia, perhaps taking it for granted that their very use betokens a renewal, as they claim. Certainly, some sites do display care in the reuse of spolia - such as Timgad, where the Byzantines generally did not recut any spolia for the fortress (built 539-40, as we know from the foundation inscription), but simply chose the blocks carefully. In the barrack houses, material was recut, but equally carefully laid (although of low quality when compared with the Roman wall). Columns are also reused in the walls, dans l'appareil du mur, remployé sans doute dans le noyeau du mur en cours de régularisation. However, the (usually inflated) late antique boast of renovatio tends (in North Africa, as in the West) to mean making good rather than completely building a fundamentis – although in some cases parallels with the renewal of the whole Empire are implicit, even if only rhetorically; and the very act may imply the reconstruction’s status as a historical monument, or yet, perhaps, as imitation of the antique , as is obviously the case with S. Mark’s, Venice, which struck at least one commentator (as it was certainly intended to do) as comparable to Hagia Sophia. Civic boasting is always irredeemably upbeat, and similar boasting, often explicit, is to be found in funerary inscriptions. Parallels are to be found in claims of military conquest, as well as in fort-building by the Arabs.
Even though Procopius is not explicit on the beautifying properties of spolia, from the actual results we can conclude that he believed spolia helped produce that effect. He describes Justinian's energetic wall-building at length and, even where ruinous walls were rebuilt, presumably with spolia, as at Kertsch and Sevastopol, he writes that the walls had fallen completely into ruin, and he made them remarkably beautiful and thoroughly safe (III.vii.10). But as an antidote to Procopius' exuberance (or mendacity), Cameron believes that a lot of Justinianic buildings were shoddy, relying on interior marble for their effect - perhaps this is why so many contemporary ekphraseis, including the section on S. Sophia in the Buildings, spend so much of their time praising the coloured marbles.  For Duval, spolia enceintes are a symbol of the continuity of civilization, just as the building of a wall marked the foundation of classical colonies. Assessing intent is always difficult, however. Thus with the Panaghia in Antalya, built with temple spolia, it is argued that the building was indeed a renovatio, being seen as new, not as old - what Gassi calls attualizazione del materiale antico. The spolia, in this interpretation, lose their connotation of antiquity, armonizzandosi perfettamente con quelli bizantini in un contesto ornamentale e architettonico unitario. This theory, even if correct, still gives little insight into how the builders viewed the spolia they used, or whether they knew what they were, and how old. But the general idea is surely analagous to display on fortifications; as Uggeri has it, the display of antiquities on churches are I parlanti monumenti della romanita, and the church un vero archivio di pietra, il luogo piu idoneo per conservare le memorie della citta.
One of the ironies of our study is that Crusaders and pilgrims certainly knew many of the places and monuments in our territories, including monuments which have since disappeared, much better than we can today reconstruct them. Myra, where S. Nicholas was still performing miracles, was a landfall for pilgrims as, further west, was the now-deserted Patara - jadis puissante et belle, a été aujourdhui [late 1330s] détruite par les turcs. Again, many important antique centres in Turkey (or rather their hinterland) were targetted for trade in the Middle Ages. We may suspect, by analogy with what happened in Europe, that this included trade in spolia, perhaps as ballast (cf.Vasari), along with staple commodities - an eastern counterpart to the marmorarii of Rome, whose work reached England and France by the early 11th century. Certainly, there is at least one narrative account of Christians selling spolia to North Africans, if only from the early 18th century. In a sense, after the Ottoman Turkish takeover, and the cutting of many of the sea and land routes, in the 16th century Western Europe, through her travellers, had to pick up the pieces of antiquarian study, and re-learn what mediaeval generations of crusaders and pilgrims probably already knew. Such travel accounts are frequently important, because we cannot trust the current appearance of monuments as necessarily identical to the mediaeval appearance - although they help us ponder on the meaning of renovatio. Even 19th century photographs give us information now otherwise lost.
Another irony, which hinders any chance we might have had of coherent contemporary discussions of the use of spolia, is the studied indifference that can be read into metropolitan Byzantine attitudes to classical statuary. Thus Cyril Mango believes that, when the Turks took the City the Hercules reliefs on the Golden Gate, and the serpent column, were the only two specimens of ancient sculpture left. He is equally mournful about Byzantine artistic engagement with the classical past, and with the impact of the past on the present: Each time we find a Byzantine representation of a classical subject, it appears, upon inspection, to be separated from its ultimate classical model by a long chain of transmission, usually in the minor arts. A penchant for relief sculpture, not to mention iconoclasm, of course, were the reasons. But an indifference to the past is surely startling, with the classical tradition killed in a city once crammed with antique artworks - whereas the use of spolia elsewhere in Turkey helps preserve that tradition. Mango's assessment seems confirmed by an early 8th century chronicle which intimates that not much material is left and, when it writes of portrait sculpture, cites work from four centuries before. Krousmmos' sack in 813 AD depleted the stock of antiquities even further. Some travellers much later found such a dearth of antiquities somewhat odd. Nevertheless, some imitation of the past continued in the matter of spolia, if we accept Foss’ suggestion that 12th-century restorations of the Land Walls followed, in using spolia, ninth-century models.
