I sing the form of war, the bloodless plain,
Armies of ivory, and a mock campaign;
How two bold kings in different armour veil'd,
One black, one white, for conquest fought the field.

Vida's Game of Chess, opening lines | Compare | Of armies on the chequer'd field array'd, And guiltless war in pleasing form display'd; When two bold kings contend with vain alarms, In ivory this, and that in ebon arms. | William Jones, Caïssa; Or, The Game of Chess.
