Numbers and letters are recurring motifs in the art of László Lakner. Numbers may allude to phases or states, to successive visual montage elements recalling film sequences, to enigmatic narratives, to cause-and-effect relationships, to the ontological question of the identicality/non-identicality of corresponding picture fields, or to the paradox of the depictability/non-depictability of time. Numbers may be graphic marks and associative motifs typical of the forms used in pop art, but besides all this they may also be metaphors of being.
