Rhomb. n.s. [rhombe, Fr. rhombus, Lat. ῥομβος.] In geometry, a parallelogram or quadrangular figure, having its four sides equal, and consisting of parallel lines, with two opposite angles acute, and two obtuse: it is formed by two equal and right cones joined together at their base.

Save the sun his labour, and that swift
Nocturnal and diurnal rhomb suppos'd
Invisible else above all stars, the wheel
Of day and night. Milton.
See how in warlike muster they appear,
In rhombs and wedges, and half moons and wings. Milton.
