After twenty miles' march they halted for the night, pursuing their way on the following morning. They had now entered a wide and fertile valley with lofty hills on either side. In some places there were stagnant marshes, and the officer in charge of the guard informed Malchus that in the autumn a pestilential miasma rose from these, rendering a sojourn in the valley fatal to the inhabitants of the mainland. The native people were wild and primitive in appearance, being clad chiefly in sheepskins. They lived in beehive shaped huts. The hills narrowed in towards the end of the day's march, and the valley terminated when the party arrived within half a mile of their destination. Here stood a small town named Metalla, with a strong Roman garrison, which supplied guards over the slaves employed in working the mines. This town is now called Iglesias.
The principal mine was situated in a narrow valley running west from the town down to the sea coast. The officer in command of the escort handed over Malchus and his companions to the charge of the officer at the head mining establishment.
Malchus was surprised at the large number of people gathered at the spot. They lived for the most part in low huts constructed of boughs or sods, and ranged in lines at the bottom of the valley or along the lower slopes of the hill. A cordon of Roman sentries was placed along the crest of the hill at either side, and a strong guard was posted in a little camp in the centre of the valley, in readiness to put down any tumult which might arise.
The great majority of the slaves gathered there were Sards, men belonging to tribes which had risen in insurrection against the Romans. There were with them others of their countrymen who were not like them slaves, though their condition was but little better except that they received a nominal rate of payment. These were called free labourers, but their labour was as much forced as was that of the slaves—each district in the island being compelled to furnish a certain amount of labourers for this or the mines further to the north. The men so conscripted were changed once in six months. With the Sards were mingled people of many nations. Here were Sicilians and members of many Italian tribes conquered by the Romans, together with Gauls from the northern plains and from Marseilles.
There were many mines worked in different parts of the island, but Metalla was the principal. The labour, in days when gunpowder had not become the servant of man, was extremely hard. The rocks had to be pierced with hand labour, the passages and galleries were of the smallest possible dimensions, the atmosphere was stifling; consequently the mortality was great, and it was necessary to keep up a constant importation of labour.
“If these people did but possess a particle of courage,” Trebon said, “they would rise, overpower the guard, and make for the forests. The whole island is, as the officer who brought us here told us, covered with mountains with the exception of the two broad plains running through it; as we could see the hills are covered with woods, and the whole Roman army could not find them if they once escaped.”
“That is true enough,” Malchus said, “but there must be at least five or six thousand slaves here. How could these find food among the mountains? They might exist for a time upon berries and grain, but they would in the end be forced to go into the valleys for food, and would then be slaughtered by the Romans. Nevertheless a small body of men could no doubt subsist among the hills, and the strength of the guard you see on the heights shows that attempts to escape are not rare. Should we find our existence intolerable here, we will at any rate try to escape. There are fifty of us, and if we agreed in common action we could certainly break through the guards and take to the hills. As you may see by their faces, the spirit of these slaves is broken. See how bent most of them are by their labour, and how their shoulders are wealed by the lashes of their taskmasters!”
The officer in charge of the mines told Malchus that he should not put him and the other two officers to labour, but would appoint them as overseers over gangs of the men, informing them that he had a brother who was at present a captive in the hands of Hannibal; and he trusted that Malchus, should he have an opportunity, would use his kind offices on his behalf.
One of the lines of huts near the Roman camp was assigned to the Carthaginians, and that evening they received rations of almost black bread similar to those served out to the others. The following morning they were set to work. Malchus and his two friends found their tasks by no means labourious, as they were appointed to look after a number of Sards employed in breaking up and sorting the lead ore as it was brought up from the mine. The men, however, returned in the evening worn out with toil. All had been at work in the mines. Some had had to crawl long distances through passages little more than three feet high and one foot wide, until they reached the broad lode of lead ore.
Here some of the party had been set to work, others had been employed in pushing on the little galleries, and there had sat for hours working in a cramped position, with pick, hammer, and wedge. Others had been lowered by ropes down shafts so narrow that when they got to the bottom it was only with extreme difficulty that they were able to stoop to work at the rock beneath their feet. Many, indeed, of these old shafts have been found in the mines of Montepone, so extremely narrow that it is supposed that they must have been bored by slaves lowered by ropes, head foremost, it appearing absolutely impossible for a man to stoop to work if lowered in the ordinary way.
