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.https://en.wikiquote.org/wiki/Marco_Girolamo_Vida
