A little study of the hinge seems to show that these branching portions were so arranged as to make the mechanical {113} moment of the swinging door less of a dead weight than it would have been if the hinge were a solid bar of iron. Besides the spreading of the branches over a wide surface serves to hold the woodwork of the door thoroughly in place. While the hinge was beautiful, then it was eminently useful from a good many standpoints, and trivial though it might be considered to be, it was in reality a type of all the work accomplished in connection with these Thirteenth Century Cathedrals. According to the old Latin proverb "_omne tulit punctum qui miscuit utile dulci_," he scores every point who mingles the useful with the beautiful, and certainly the Thirteenth Century workman succeeded in accomplishing the desideratum to an eminent degree. This mingling of the useful and the beautiful is of itself a supreme difference between the Thirteenth Century generations and our own. Mr. Yeats, the well known Irish poet, in bidding farewell to America some years ago said to a party of friends, that no country could consider itself to be making real progress in culture until the very utensils in the kitchen were beautiful as well as useful. Anything that is merely useful is hideous, and anyone who can handle such things with impunity has not true culture. In the Thirteenth Century they never by any chance made anything that was merely useful, especially not if it was to be associated with their beloved Cathedral.
