“If the slave was generally absent from the rural landscape, the tenant farmer (colonus) was an important feature of it. A man of degraded and anomalous status, the colonus was theoretically free, but in practice tied to his plot. He was, as a law of [AD] 393 puts it, ‘a slave of the land’. His condition was hereditary, his freedom to marry restricted, and he could not even join the army. The master of his land collected his taxes and was empowered to put him in chains if he tried to run away. It was openly admitted by the government that there was little difference between the status of a slave and that of a colonus. The authorities, of course, were not animated by pure sadism in curbing the liberties of the tenant farmer; their primary concern was the collection of tax.” – Cyril Mango, Byzantium: The Empire of New Rome
