Notes 1 My purpose here has been to present a general survey of a vast subject, ra<strong>the</strong>r than to offer a research paper. References have thus been kept to a m<strong>in</strong>imum, <strong>and</strong> for this <strong>the</strong> reader’s <strong>in</strong>dulgence is requested. Much of <strong>the</strong> material will be reexam<strong>in</strong>ed, with full documentation, <strong>in</strong> a book be<strong>in</strong>g prepared <strong>in</strong> collaboration with Sheila Gibson, whose help is gratefully acknowledged. 2 At <strong>the</strong> conference one member of <strong>the</strong> audience took issue with details of <strong>the</strong> architectural term<strong>in</strong>ology used, <strong>in</strong> particular with <strong>the</strong> term ‘concrete’. It is, of course, well known that what we have called ‘concrete’ is not concrete <strong>in</strong> <strong>the</strong> modern sense, but <strong>the</strong> term is reta<strong>in</strong>ed for convenience <strong>and</strong> out of deference to established usage. Any fur<strong>the</strong>r comments <strong>and</strong> suggestions will be very welcome. References 27 L<strong>in</strong>g: The mechanics of <strong>the</strong> build<strong>in</strong>g trade
Who paid for public build<strong>in</strong>gs <strong>in</strong> Roman cities? Our <strong>in</strong>formation about who paid for public build<strong>in</strong>gs <strong>in</strong> Roman Brita<strong>in</strong> is ra<strong>the</strong>r limited. Many <strong>in</strong>scriptions show <strong>the</strong> army carry<strong>in</strong>g out build<strong>in</strong>g work. Where this occurred, it was <strong>the</strong> government who paid, not <strong>the</strong> local community. But <strong>the</strong>se <strong>in</strong>scriptions ma<strong>in</strong>ly refer to military zones. There is little direct <strong>in</strong>formation about how build<strong>in</strong>gs were f<strong>in</strong>anced <strong>in</strong> civilian towns <strong>and</strong> villages <strong>in</strong> Brita<strong>in</strong>. I shall turn, <strong>the</strong>refore, to evidence from <strong>the</strong> Mediterranean <strong>and</strong> look <strong>in</strong> particular at Rome’s North African prov<strong>in</strong>ces. Many more answers to <strong>the</strong> question ‘who paid for public build<strong>in</strong>g?’ can be found here. There may not be any straightforward analogy between Africa <strong>and</strong> a nor<strong>the</strong>rn prov<strong>in</strong>ce such as Brita<strong>in</strong>: <strong>the</strong>re were crucial differences not only <strong>in</strong> climate <strong>and</strong> geography, but also <strong>in</strong> <strong>the</strong> level of Italian settlement <strong>in</strong> <strong>the</strong> two areas. Never<strong>the</strong>less, a description of how th<strong>in</strong>gs stood <strong>in</strong> one part of <strong>the</strong> <strong>Empire</strong> must demonstrate possibilities that would have existed <strong>in</strong> any of <strong>the</strong> prov<strong>in</strong>ces. Before we look at different systems of f<strong>in</strong>anc<strong>in</strong>g, it is worth say<strong>in</strong>g that some Roman public build<strong>in</strong>gs were not paid for at all. Cicero (In Verrem, ii.5.48) speaks of <strong>the</strong> ancient Capitol at Rome as hav<strong>in</strong>g been built for noth<strong>in</strong>g, because it was built with forced labour. Livy (i.56.l-2) says that <strong>the</strong> Capitol was built with a mixture of forced labour <strong>and</strong> public funds. Whatever we th<strong>in</strong>k of statements about Rome’s early past, forced labour on public works cont<strong>in</strong>ues to figure <strong>in</strong> Rome’s later history where <strong>the</strong>re is better documentation. One of <strong>the</strong> more severe punishments <strong>in</strong>flicted by law under <strong>the</strong> <strong>Empire</strong> was damnatio ad opus publicum, be<strong>in</strong>g condemned to labour on public works (cf Berger 1953,610). When <strong>the</strong> younger Pl<strong>in</strong>y was govern<strong>in</strong>g Bithynia under Trajan, he found many men <strong>in</strong> <strong>the</strong> largest cities who had been condemned ad opus publicum, but who had managed to escape. Instead of work<strong>in</strong>g on build<strong>in</strong>gs, <strong>the</strong>y had found employment <strong>in</strong> <strong>the</strong> city as public slaves, which was evidently preferable. The emperor ruled that <strong>the</strong>se men must go back to <strong>the</strong>ir orig<strong>in</strong>al punishment, unless <strong>the</strong>y had been condemned more than ten years previously. Trajan laid down that <strong>the</strong>y must work on servic<strong>in</strong>g public baths, clean<strong>in</strong>g sewers, <strong>and</strong> build<strong>in</strong>g roads <strong>and</strong> streets. This is a valuable def<strong>in</strong>ition of what ad opus publicum meant, <strong>and</strong> it clearly does <strong>in</strong>clude work<strong>in</strong>g on major build<strong>in</strong>g works (Pl<strong>in</strong>y, Epistulae, x.31-2; for corvée <strong>in</strong> <strong>the</strong> Digest, cf Brunt 1980, 82, n5). The supply of crim<strong>in</strong>als sentenced <strong>in</strong> this way was not necessarily sufficient. In <strong>the</strong> town-charter from Urso <strong>in</strong> Spa<strong>in</strong> (ILS 6087,98) <strong>the</strong>re is a provision for conscript<strong>in</strong>g <strong>the</strong> citizens <strong>and</strong> o<strong>the</strong>r <strong>in</strong>habitants of <strong>the</strong> town if <strong>the</strong> magistrates are carry<strong>in</strong>g out build<strong>in</strong>g works. This may look to us very severe, s<strong>in</strong>ce it apparently places <strong>the</strong> free citizen on a level with <strong>the</strong> serious crim<strong>in</strong>al. But <strong>the</strong> amount of time that each citizen had to contribute was very short. The st<strong>in</strong>t was five days per year, with exemption for anyone aged over 60 or under 14. The owners of teams of 28 R P Duncan-Jones oxen had to contribute <strong>the</strong>se also, <strong>the</strong> st<strong>in</strong>t for ox-teams be<strong>in</strong>g three days per year. 2 In Egypt <strong>the</strong>re was a similar st<strong>and</strong>ard requirement of five days’ labour per year, to be spent <strong>in</strong> clean<strong>in</strong>g out <strong>the</strong> irrigation channels on which Egypt depended (Sijpeste<strong>in</strong> 1964). In <strong>the</strong> nature of th<strong>in</strong>gs, compulsory labour or corvée is very rarely mentioned <strong>in</strong> build<strong>in</strong>g <strong>in</strong>scriptions. The magistrate who had access to quantities of labour from crim<strong>in</strong>als or even from ord<strong>in</strong>ary townsfolk was very unlikely to mention this <strong>in</strong> <strong>the</strong> <strong>in</strong>scription of <strong>the</strong> build<strong>in</strong>g he was putt<strong>in</strong>g up. But <strong>the</strong>re are a few exceptions. The colony of Auzia <strong>in</strong> Mauretania built a covered market <strong>in</strong> <strong>the</strong> year 230; <strong>the</strong> <strong>in</strong>scription (ILS 5590) says it was provided from <strong>the</strong> sportulae of <strong>the</strong> decurions, but also by <strong>the</strong> operae, <strong>the</strong> labour contributions, of <strong>the</strong> people of <strong>the</strong> town. In ano<strong>the</strong>r case we can still see build<strong>in</strong>g works that were carried out <strong>in</strong> this way. At Tiddis, one of <strong>the</strong> castella of Cirta <strong>in</strong> central Numidia, big ra<strong>in</strong>water cisterns were constructed to feed <strong>the</strong> town baths <strong>in</strong> <strong>the</strong> 250s. The work <strong>in</strong>cluded pull<strong>in</strong>g down <strong>the</strong> ru<strong>in</strong>s of previous build<strong>in</strong>gs <strong>and</strong> levell<strong>in</strong>g <strong>the</strong> site. It was carried out ‘per populum’, by <strong>the</strong> labour of <strong>the</strong> citizens <strong>the</strong>mselves (ILAlg ii. 1.3596). We f<strong>in</strong>d a few o<strong>the</strong>r references to build<strong>in</strong>g labour provided by <strong>the</strong> citizens <strong>in</strong> Mauretanian <strong>in</strong>scriptions of <strong>the</strong> early or mid 3rd century (ILS 6887-9). Forced labour, when it is mentioned <strong>in</strong> <strong>the</strong> <strong>in</strong>scriptions, is always <strong>the</strong> labour of free citizens. Work by crim<strong>in</strong>als, if recorded at all, would usually count as f<strong>in</strong>anc<strong>in</strong>g from public funds. When <strong>the</strong> emperor is recorded as a major road-builder, <strong>the</strong> labour, unless explicitly provided by <strong>the</strong> army, may well have been crim<strong>in</strong>al labour. 3 An enormous project like Claudius’s attempt to dra<strong>in</strong> <strong>the</strong> Fuc<strong>in</strong>e lake, which occupied 30,000 men for eleven years, is likely to have depended on crim<strong>in</strong>al labour, <strong>and</strong> when Nero tried to cut a canal through <strong>the</strong> isthmus of Cor<strong>in</strong>th, he had crim<strong>in</strong>als, apparently sent from all over <strong>the</strong> <strong>Empire</strong>, to work on it (Suetonius, Claudius, 20.2; ps-Lucian, Nero, 3; cf Dio, lxii. 16.2). Though forced labour may have been crucial to some imperial build<strong>in</strong>g projects, public build<strong>in</strong>gs <strong>in</strong> secondary towns were normally paid for <strong>in</strong> money. Us<strong>in</strong>g <strong>the</strong> citizens <strong>the</strong>mselves as workers on a large scale, as at Tiddis, was a sign that money was lack<strong>in</strong>g. This may be why <strong>the</strong> few epigraphic references to direct labour come from communities which were ei<strong>the</strong>r very small or very remote. The typical build<strong>in</strong>g <strong>in</strong>scription, <strong>in</strong> contrast, tells us that <strong>the</strong> build<strong>in</strong>g was paid for with town funds or by a private <strong>in</strong>dividual. That does not necessarily mean that <strong>the</strong> labour was free. The contractors who undertook to put up a build<strong>in</strong>g for cash may have employed a ma<strong>in</strong>ly servile workforce. At <strong>the</strong> end of <strong>the</strong> Republic Crassus had a big labour-force of slaves engaged <strong>in</strong> build<strong>in</strong>g redevelopment <strong>in</strong> Rome (Plutarch, Crassus, 2.4; for free build<strong>in</strong>g labour <strong>in</strong> <strong>the</strong> city of Rome, see Brunt 1980). In <strong>the</strong>ory a Roman town should have been capable of
