The Forbidden Tree by Rafael Trelles; born in Puerto Rico with a bachelor’s degree in Plastic Arts from the University of Puerto Rico and graduate studies at the Academia San Carlos, Universidad Autonoma de Mexico; is a dry tree painted red located in the middle of a pond. The presence of this tree is filled with mythological, archetypal, but above all theological references for its purpose is to alarm us from the past of the future. It is about a call to reflection as asserted by the artist about our endangered natural environment; “The human being has disobeyed and is at the verge of expulsion from his only paradise”.
