Robin Hood - who in his earliest manifestations was referred to by names including "Robehod", "Robbehod" and "Rabunhod" - began to be cited in the rolls of English Justices, across a wide area of central England, from 1281 onwards. The form of the references seems to allude to a popular folklore. Although they offer little specificity, they generally appear to characterise Robin Hood as an outlaw, associated with the practice of robbing from the rich and giving instead to the poor.
