Occasionally what seems at first sight a medallion window resolves itself, as at S. Kunibert, Cologne, into a kind of genealogical tree, enclosing subjects illustrative of the descent of Christ. The rather unusual combination of medallion and vine shown [below], also German, is of rather later date.

In the fourteenth century the tree naturally becomes a vine, usually in colour upon a blue or ruby ground, extending beyond the limits of a single light, and crossing not only the mullions, but the borders (which, by the way, often confuse the effect of a Decorated Jesse window). The vine extends also very often into the tracery, where sits the Virgin with the Infant Christ. The figure of our Lord is always, of course, the topmost feature of the tree—in the arms of the Virgin, in the lap of the Father, or sitting in Majesty. A variation upon ordinary practice occurs where the Father supports a crucifix. The figure of Jesse naturally, as at Shrewsbury ([page 241]), extends across several lights.

Occasionally a figure and canopy window proves to be also a Jesse window—a vine, that is to say, winds about the figures, and connects them with the figure of Jesse; but this combination of canopy work with tree work (as at Wells, some of the detail of which is given [overleaf]) is confused and confusing. A much happier combination of figures under canopies with tree work occurs in a sixteenth century window at S. Godard, Rouen, which has at the base a series of five figures, above whom spreads the tree, its roots appearing above the head of the central one, who proves to be Jesse.

By the fifteenth century the vine is rather more conventionally treated. It is usually in white and stain upon a coloured ground, or, if the leaves are green, the stems are white and stain. The figures also have more white in their drapery. In the earlier part of the century the main stem branches very often in an angular manner so as to form six-sided bowers for the figures, framing them, perhaps, in a different colour from the general groundwork of the window. Or the various lights of the window may have alternately a blue and a ruby ground. It is rarely that two figures are shown in the width of a single light, either in separate compartments or grouped in one.
