1973 Antonio Fernández Molina (Spanish poet, author, Art Critic)
"Amengual has a very solid professional preparation, he has studied art, knows well the techniques of painting and is constantly investigating in this field. However he could never be satisfied with only whatever he might learn of technical possibilities of expression. Art is very much more than that for him. Above all it is an adventure during which the artist reflects the times in which he is living whilst expressing his own inner self. Amengual's birth, childhood years and youth in Argentine are clearly present in his work as well as, if not the echoes then certainly, the atmosphere of such singular and differing Argentinian artists such as Xul Solar, Antonio Berni or Lucio Fontana. To all this are added his ample experiences since then and everyday impressions. So, without his origin being of a self-taught and intuitive artist, Amengual tends to express himself , by means of his splendid professional education, through extreme soulsearching within areas which are only penetrable by intuition and poetry."

1974 Miguel Angel Asturias (South American writer, Nobel Prize)
"I believe that the work of Rafael Amengual has a great quality and tremendous strength."

1974 Cristóbal Serra (Mallorcan writer and translator, specialist in William Blake)
"Within every painter who considers himself modern, a part of himself survives which is always fresh and childlike. Without actually intending to do so, he drinks from the fountain of youth. Also in his personality is a hunter of birds, a beater of game. Amengual has always incorporated in the pictoric aspect the instinct of a hunter who is successful in capturing his prey. And for that neither short nor far-sight will do. One must know how to see, and to decipher, and have considerable skill. A superficial glance might lead us to believe that Amengual does not draw very much, that he seeks abstraction and no more. But if we examine the Amengualian painting, we realize that it comprises both technique and inspiration and that he is a painter who conceals an extremely ambitious expressive purpose."

1976 Blai Bonet (Mallorcan writer and Art Critic)
"His present creative work is among the most perfectly serious, most endowed with mental vision and aesthetically elegant being done in Europe at the present time. By use of his visual language, Amengual leads the observer to discover and recognise, for the first time at least in Spain, that Painting either reveals with the form of the Times and the time of Colour the sense of dependence (upon a Superior Being), or reveals nothing at all; above all it does not reveal or express Painting itself."

1977 Josep Meliá (Mallorcan Writer, Art Critic, Lawyer and Politician)
Rafael Amengual achieves a solid and admirable level of maturity in this exhibition. His art admits a profound reading, replete with evocations and keys. Its richness, therefore,as it is presented as transcendental, incorporating the sentiment of divinity, deserves serene, pure and prejudice-free contemplation, characterised by an exercise in reflection and examination of conscience - of the conscience of each individual and the conscience of society in general. Because here exposed in synthesis are the great interrogatives which weigh upon us all - the impotence and the greatness of humanity. This is beautiful painting to be seen and experienced."

1979 Cesáreo Rodriíguez-Aguilera (President of the High Court in Palma de Mallorca, Art Critic)
"In Rafael Amengual's work one senses the culture of our times, the wounded sensitivity of the misunderstood, and the search for new realities. In a specific way, he reveals the individual outline of his personality, we are aware of his very careful consciousness of the material itself, the harmony of the colours (or almost Spartan absence of those colours on some occasions) and above all his new way of using ancient symbols."

1981 J. Corredor-Matheos (Editor, Art Critic)
The ambition of this painting emerges from the subject with the inmense depth with which the artist has confronted that theme. The way of understanding colour and the expressive brushstrokes situate the observer in the present day, within the parameters of pure painting, sharing the artist's sensual almost physical pleasure in manipulating the pigments. But his subjects, symbolism and concept of art as a vehicle to attain the profound fulfilment of a creative artist, his belief that art is not merely an aesthetic adventure, but a person's absolute compromise, distinguishes Amengual from the great majority of creative artists in the present day and age."

1993 Cristina Ros (Art Critic)
"Almost without realizing it and from the deepest of memories, Rafael Amengual translates ancient universal symbols, with strong magic, which he appropriates and adopts because for him they are his own, as they were for so many civilizations and beliefs, representing the very hub of life. And in this way he has accumulated in his particular world the rich experiences of his journey through life, and with each step along the way he has developed the cyphers of his own private language. Rafael Amengual is an artist who has opted for the least visible of realities, the kind we all keep very deep inside ourselves and do our best not to let them appear on the surface. In his painting there are no images or rather only subconscious images appear. Gestures are sparce too, in a search for unlimited purity. His is a language of relationships, essentials and symbols."
