The floor is covered with an oilcloth mosaic of jade and azure and cinnabar rhomboids. — Ulysses, James Joyce
I saw again those gray moving shapes on the roof, saw Esdaile suddenly stride to the blind-cords, saw the movement with which he had bidden me do the same, and the little bright gold rhomboids of light in the rafters as the deep blue blinds had been shut. — A Case in Camera, Oliver Onions
Some of these plants are spherical, some rhomboid, and some of an oblong shape, and all of those either black, bright-coloured, or tawny, rude to the touch, and mantled with a quickly-blasted-away coat, yet such a one as is of a delicious taste and savour to all shrill and sweetly-singing birds, such as linnets, goldfinches, larks, canary birds, yellow-hammers, and others of that airy chirping choir; but it would quite extinguish the natural heat and procreative virtue of the semence of any man who would eat much and often of it. — Gargantua and Pantagruel, François Rabelais
