The Order of the Thistle has a Collar composed of thistles alternating with a badge made of four sprigs of the ancient rue interlaced, the whole being enamelled in the proper colours. Depending from the centre thistle of the collar is the Badge, a star of eight points bearing the figure of St. Andrew supporting his white cross. His gown is green and the surcoat purple, and he stands on a mount of green. When not used with the collar the Jewel hangs from the dark green ribbon that is worn over the left shoulder. Fig. 171 from the series at Alloa House shows a method of treating the collar in gesso photographed before painting. The star of the order consists of a silver St. Andrew’s cross having rays issuing from its angles and bearing in the centre a thistle within a circle of green enamel, that is edged with gold and bears in golden letters the motto, “Nemo me impune lacessit.” It is this circle and motto that are placed round the shields of the knights of the order and sometimes with the collar in addition. [Illustration: FIG. 171.--Shield with Collar of the Order of the Thistle. Arms of John, sixth Earl of Mar, K.T. Gesso, before painting. Geo. W. Eve.] The Knights of the Order of St. Patrick surround their arms with the sky-blue circle of that order inscribed with the motto, “Quis separabit,” and the date MDCCLXXXIII. The Collar is composed of roses and harps alternately, tied together with knots of gold. The roses are double and are white within red, and red within white alternately, like those of the Garter collar. In the centre is an imperial crown ensigning a harp from which hangs the badge of gold, oval in shape, and surrounded with a wreath of shamrocks which encloses the circle of light blue enamel on which is the motto and the date MDCCLXXXIII in golden letters. Within the circle is the cross of St. Patrick, Gules on a field Argent, surmounted with a trefoil slipped and with each of its leaves charged with an imperial crown, Or. The star is of eight points, the perpendicular and horizontal rays being larger than the diagonal ones, and bears the device within a motto circle exactly similar to those of the badge, but without the shamrock wreath. These are the three principal orders which form a group that is somewhat apart from the rest. In the foregoing orders consisting, as was customary in earlier times, of a Grand Master and of Knight Companions ranking equally among themselves, the amount of insignia associated with their arms is unimportant as a mark of rank, the simplest being equally efficacious heraldically with the more elaborate. In the case, however, of orders which are divided into classes, the different parts of the insignia have acquired a special importance as indications of rank within the order which must be very carefully observed.
