These men in turn taught their children to read and write, wishing that some part of the wisdom of the ancients might be preserved. They themselves wrote down what they knew, and these manuscripts, transmitted to their children, were saved with care. Some of them remain to this day. These children, growing to manhood, took more upon them, and assumed higher authority as the past was forgotten, and the original equality of all men lost in antiquity. The small enclosed farms of their fathers became enlarged to estates, the estates became towns, and thus, by degrees, the order of the nobility was formed. As they intermarried only among themselves, they preserved a certain individuality. At this day a noble is at once known, no matter how coarsely he may be dressed, or how brutal his habits, by his delicacy of feature, his air of command, even by his softness of skin and fineness of hair. Still the art of reading and writing is scrupulously imparted to all their legitimate offspring, and scrupulously confined to them alone. It is true that they do not use it except on rare occasions when necessity demands, being wholly given over to the chase, to war, and politics, but they retain the knowledge. Indeed, were a noble to be known not to be able to read and write, the prince would at once degrade him, and the sentence would be upheld by the entire caste. No other but the nobles are permitted to acquire these arts; if any attempt to do so, they are enslaved and punished. But none do attempt; of what avail would it be to them? All knowledge is thus retained in the possession of the nobles; they do not use it, but the physicians, for instance, who are famous, are so because by favour of some baron, they have learned receipts in the ancient manuscripts which have been mentioned. One virtue, and one only, adorns this exclusive caste; they are courageous to the verge of madness. I had almost omitted to state that the merchants know how to read and write, having special license and permits to do so, without which they may not correspond. There are few books, and still fewer to read them; and these all in manuscript, for though the way to print is not lost, it is not employed since no one wants books. CHAPTER V THE LAKE There now only remains the geography of our country to be treated of before the history is commenced. Now the most striking difference between the country as we know it and as it was known to the ancients is the existence of the great Lake in the centre of the island. From the Red Rocks (by the Severn) hither, the most direct route a galley can follow is considered to be about 200 miles in length, and it is a journey which often takes a week even for a vessel well manned, because the course, as it turns round the islands, faces so many points of the compass, and therefore the oarsmen are sure to have to labour in the teeth of the wind, no matter which way it blows.
