This latter consideration was one of no small importance, as we can readily see by sending the thought back to the time when tapestries led a very different life (so human they seem in their association with men that the expression must be allowed) from that of to-day, when they are secured to stretchers, or lined, or even framed behind glass like an easel painting.
In those other times of romance and chivalry a great man's tapestries were always en route. Like their owner, they were continually going on long marches, nor were they allowed to rest long in one place. From the familiar castle walls they were taken down to line the next habitat of their owner, and that might be the castle of some other lord, or it might be the tent of an encampment. Again, it might be that an open-air exposition for a pageant, was the temporary use.
The tapestries thus bundled about, forever hung and unhung on hooks well or ill-spaced, handled roughly by unknowing varlets or dull soldiers, these tapestries suffered much, even to the point of dilapidation, and thus arose the need for a tape border, and thus it happens also that the relics of that time are found mainly among the religious pieces. These last found safe asylum within convent walls or in the sombre quiet of cathedral shades, and like all who dwell within such precincts were protected from contact with a rude world.
One day, sitting solitary at his wools, it occurred to the weaver of the early Fifteenth Century to spill some of his flowers out upon the dark galloon that edged his work. The effect was charming. He experimented further, went into the enchanted wood of such a design as that of _The Lady and the Unicorn_ to pluck more flowers, and of them wove a solid garland, symmetrical, strong, with which to frame the picture. To keep from confounding this with the airy bells and starry corollas of the tender inspiring blossoms of the work, he made them bolder, trained them to their service in solid symmetric mass, and edged the whole, both sides, with the accustomed two-inch line of solid rich maroon or blue.
It is easy to see the process of mind. For a long time there had been gropings, the feeling that some sort of border was needed, a division line between the world of reality and the world of fable. Examine the Arras work and see to what tricks the artist had recourse. The architectural resource of columns, for example; where he could do so, the artist decoyed one to the margin. Thus he slipped in a frame, and broke none of the canons of his art, and no more beautiful frame could have been devised, as we see by following up the development and use of the column. Once out from its position in the edge of the picture into its post in the border, it never stops in its beauty of growth until it reaches such perfection as is seen in the twisted and garlanded columns which flank the Rubens series, and those superb shafts in _The Royal Residences_ of Lebrun at the Gobelins under Louis XIV.
