[[Renatus Cartesius]] scripsit de eis in sua ''[[Geometria Cartesii|Geometria]]'', ubi appellatio estferit quasi irrisio.<ref name="Martinez">Alberto A. Martinez, ''Negative Math: How Mathematical Rules Can Be Positively Bent'' (Princeton University Press, [[2005]]), discusses ambiguities of meaning in imaginary expressions in historical context.</ref>
