But there were other views in which those who devoted themselves to a monastic life might be supposed useful to society. They were often employed either in cultivating their gardens, or in curious mechanical works; as indeed the nuns are still famous for many elegant and ingenious manufactures. By the constant communication they had with those of their own order, and with their common head at Rome, they maintained some intercourse between nations at a time when travelling was dangerous, and commerce had not, as now, made the most distant parts of the globe familiar to each other: and they kept up a more intimate bond of union amongst learned men of all countries, who would otherwise have been secluded from all knowledge of each other. A monk might travel with more convenience than any one else; his person was safer, and he was sure of meeting with proper accommodations. The intercourse with Rome must have been peculiarly favourable to these northern nations; as Italy for a long time led the way in every improvement of politeness or literature: and if we imported their superstition, we likewise imported their manufactures, their knowledge, and their taste. Thus Alfred sent for Italian monks, when he wanted to civilize his people, and introduce amongst them some tincture of letters. It may likewise be presumed that they tempered the rigour of monarchy. Indeed they, as well as the sovereigns, endeavoured to enslave the people; but subjection was not likely to be so abject and unlimited where the object of it was divided, and each showed by turns that the other might be opposed. It must have been of service to the cause of liberty to have a set of men, whose laws, privileges, and immunities the most daring kings were afraid to trample on; and this, before a more enlightened spirit of freedom had arisen, might have its effect in preventing the states of christendom from falling into such entire slavery as the Asiatics. Such an order would in some degree check the excessive regard paid to birth. A man of mean origin and obscure parentage saw himself excluded from almost every path of secular preferment, and almost treated as a being of an inferior species by the high and haughty spirit of the gentry; but he was at liberty to aspire to the highest dignities of the church; and there have been many who, like Sextus V. and cardinal Wolsey, have by their industry and personal merit alone raised themselves to a level with kings.
