Decay works is a manifestation of what is hidden in the artist and which is being expressed through his work. In these works, the psyche and the unconsciousness of the artist (as well of the spectator) take up an important position. The way in which this series comes about happens according to a process at which Herck a priori has no insight into what the result will be. Once it is there, he can reconstruct the path that led to this end. Thus, every work is independent and carries a stratification and complexity.
