In his work Wagner returns repeatedly to a geometric formal language that is reduced in its composition and abstractly constructed.
Thus drawings, watercolours, silkscreen prints, gouache and acrylic paintings have a fixed place in Wagner’s repertoire.
[1] He chooses clean, geometric forms, amongst others, and carries these over into his subjects, "or even onto the picture’s topic, which has no inherent geometry, like clouds or rain, for example," as Friedrich Meschde has explained.
For example, Alexander Wagner has produced photographs in which a chance description of space in terms of geometry can be recognised, in the form of an everyday object.
[1] His newest works are increasingly wall paintings, as have been on display recently in the Kunsthalle Bielefeld, amongst other venues.
