"Let any irregularly shpaed body, as a stone or chair, be suspended so as to move freely. Drop a plumb line from the point of the suspendsion, and make it fast or mark its direction. The center of mass will lie in this line. From a second point, not in the line already determined, suspend the body; let it fall a plumb line as before. The center of mass will lie in this line also. But to lie in both lines, it must lie at their intersection." -Avery 1895

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.
