The central figures in this piece represent Charles II. and his Queen, Catherine of Braganza, who is represented with that curious lock of hair on her forehead to which the King took so much objection when he saw it for the first time upon her arrival at Southampton. The portraits within the four circles have not at present been recognised. The late owner of this piece purchased it in Hammersmith, and from the fact that Queen Catherine had a house there it is possible that it may have once been a royal possession. Size, 13-1/2 × 17-1/2.] Knot-Stitches [Illustration: FIG. 66.--FACE WORKED IN SPLIT-STITCH: ENLARGED FROM LOWER PORTION (NOT REPRODUCED) OF FIG. 64.] Knot-stitches--these, by the way, have no connection with the knotting-work popular at the end of the seventeenth century--are introduced freely into the stump-work pictures to represent the hair of the human figures, together with the woolly coats of sheep and the sundry and divers unclassified animals invariably found in this type of embroidered picture. These knots or knotted stitches range from the small, tightly-worked French knots which, when closely massed, produce a sufficiently realistic imitation of a fleece, to the long bullion knots formed by twisting the silk thread ten or twelve times round the needle before drawing the latter through the loops. The sheep (enlarged from Fig. 64) in Fig. 67 shows very clearly the effect of the massed French knots. The longer knot-stitches are found to be arranged in even loops sewn closely together, or are worked loosely and placed irregularly to meet the requirements of the design. Knot-stitches of all kinds are seen, too, in the foliage, grass, and mossy banks, although for these couchings of loops of fine cord, untwisted silk and gimp, as well as of purl, seem to have been equally popular. At a later period, that is, towards the middle of the eighteenth century, chenille replaced knot-stitches, couched loops, and purl for the purpose, but it proved much less satisfactory both as regards appearance and durability. [Illustration: FIG. 67.--KNOTTED-STITCH: ENLARGED FROM EMBROIDERY REPRODUCED IN FIG. 64.] Looped-stitches are also used to indicate flowing ringlets, for which the bullion knots would be too formal, as may be seen in Figs. 65 and 66. The loops in these examples are of partly untwisted gimp. In flat embroidery, it may be mentioned, the hair is frequently worked in long-and-short or split stitch, or in short, flat satin-stitches, the lines whereof are cleverly arranged to follow the twists of the curls. In this way the hair of the lady, shown on an enlarged scale in Fig. 66, is worked. Plush-Stitch
