“Their manners are simple and honest. They are proud and reserved. If any one is kind to them, he can be sure of their gratitude, but if any one injures them they will take their revenge. They will risk their lives to wipe out dishonour. If any one in distress appeals to them, they will lay aside all thought of self in their anxiety to help. Even if they have an insult to avenge, they never fail to warn their enemy. In battle, if they pursue the fugitives they always spare all who surrender. . . . These men love study and there are many heretics among them.”
