A HISTORY OF DERBYSHIRE south and Castlcton on the north. Within these limits disused mines of one date or another occur plentifully in large irregular patches. (See map, fig. 28.) The Roman mining seems to have centred round a point in the south- east of this region. Five out of the six pigs of Roman lead found in the county have been dug up on the moors in the vicinity of Matlock, east or west of the Derwent, and the circumstances of their discovery seem to indicate that they were melted down at the places where they were discovered. It does not follow, of course, that they were mined where they were smelted. The ore may possibly have been mined elsewhere, and the neighbourhood of Matlock may have been only a smelting district where the lead was separated from the more valuable silver which it contained. But the sites where the five pigs have been found are somewhat scattered ; they lie also on the edge of the mining region, and it is more natural to suppose that the lead was both mined and smelted near Matlock. The region or some part of it seems to have borne the name Lutudarum and the mining district the name metal- lum Lutuda- rense. 1 Mining was here carried FIG. 29.

Lutudaren- sian pigs from near Matlock, but also seven others found in various parts of England which are declared by their inscriptions to come from the same source. One of the pigs is dated to the reign of Hadrian (A.D. 1 1 7- 138); and so far as one may judge by the lettering the others may be even earlier. Thus much seems certain respecting the Derbyshire mining. If, however, we inquire for further details, many puzzles confront us. In the first place, with respect to the ownership and administration. Minerals in the Roman Empire were usually crown property, and were either worked by the state or were let to more or less official lessees under the control of an imperial agent. In the reign of Hadrian, as pig No. i shows, the Derbyshire lead mines did thus belong to the emperor. But most of the pigs bear not the emperors' names, but those of private persons or at least of persons who have no official titles or descriptions. L. Aruconius Verecundus, C. lulius Protus, Ti. Claudius Tr(ophimus ?), P. Rubrius Abascantus. These are the only private persons named 1 Compare the inscriptions given below with the Ravenna Geographer, 429. 2, who mentions Lutudaron next to Derventio. For some obscure reason almost all writers previous to the discovery of No. II called the name Lutudae ; but it is obviously Lutudarum. Holder (Sprachschatz, ii. 355) is certainly wrong in adhering to Lutudae. 228
