This design dates back to Solomon's time. It is one of the Chinese Buddhist ornaments and is therefore quite commonly found in the Samarkand, Yarkand, Kashgar, and the various Chinese products. Also used more or less throughout the Caucasus and especially in the Shemakha; in fact, it is present somewhere in most rugs of the latter class, as a talismanic design. In some of the Persian fabrics it partakes of a floral character.

Ladder bracket on the back of a ladder. These are made in various styles. Some fasten to rungs. This one attaches to the siderails. It is not, therefore, likely to depend upon a defective rung and so it is safer. They are used as shown on the outside of the ladder to hold a plank at the top of two extension ladders in painting roof cornices. It is possible to swing these brackets to a position on the under side of the ladders. There they make an excellent scaffold from which to work on a wall or window frame.

In the Roman Republic, and later the Empire, the curule seat was the chair upon which senior magistrates were entitled to sit, including dictators, masters of the horse, consuls, praetors, censors, and the curule aediles. he curule chair was traditionally made of or veneered with ivory, with curved legs forming a wide X; it had no back, and low arms. The chair could be folded, and thus an easily transportable seat, originally for magisterial and promagisterial commanders in the field, developed a hieratic significance, expressed in fictive curule seats on funerary monuments, a symbol of power which was never entirely lost in post-Roman European tradition. Sixth-century consular ivory diptychs of Orestes and of Constantinus each depict the consul seated on an elaborate curule seat with crossed animal legs.
