1871 B. Taylor tr. J. W. von Goethe Faust (Boston ed.) I. Notes 336/2 Paracelsus ascribes a similar, though a lesser, degree of virtue to the hexagram.

2. Geometry. A figure of six lines.The term is spec. applied to: (a) Pascal's mystic hexagram, which is formed by lines joining six points on a conic, and has the property that the intersections of the first and fourth, the second and fifth, and the third and sixth of these lines lie on one straight line; (b) Brianchon's hexagram, which is a six-sided figure circumscribed about a conic, and has the property that the three lines joining opposite angles intersect in one point.

1863 R. Townsend Chapters on Mod. Geom. I. 145 In a hexastigm or hexagram every triangle determined by three points or lines is said to be the opposite of that determined by the remaining three.

1885 Encycl. Brit. XVIII. 338 He [Pascal] established the famous theorem that the intersections of the three pairs of opposite sides of a hexagon inscribed in a conic are collinear. This proposition, which he called the mystic hexagram, he made the keystone of his theory.

3. In Chinese literature, one of the sixty-four figures, consisting each of six parallel (whole or divided) lines, which form the basis of the ‘Yih-king’ or ‘book of changes’.

1882 Athenæum 2 Sept. 296/3 The ‘Yi King’, or ‘Book of Changes’, consists of sixty-four hexagrams, the component parts of which are whole or divided lines, placed one over the other in a certain fanciful order, and called by a name which in its turn suggests an explanation found in the text.
