You have only to examine the crossing of the white lines in any of these last-mentioned patterns to see that, now that they are not separately glazed, they do not really interlace as before. It is out of the question that they should.

It is easy enough to glaze up bands so that they shall interlace; but, when some of the drawing lines are lead and some paint, it occurs continually that you want a leaded line to pass behind a line of clear glass—which, of course, is a physical impossibility. It follows that the pretended interlacing comes to grief. The pattern is confused (it is worse when there is no hatched background) by the occurrence of leads, stronger than the painted lines, which, so far from playing any part in the design, occur just at the points where they most interfere with it.

That this did not deter them, that they made a shift with interlacing which does not truly interlace, marks a falling off in what may be called the conscientiousness of the Gothic designers. French and English Decorated grisaille, effective as it often is in the window, is distinctly less satisfactory in design than the common run of earlier work. Its charm is never in its detail.

The patterns may be ingenious and not without grace, but they are never altogether admirable, any more than are the figures.
