Carmelo Arden Quin (1913-2010) was a Uruguayan artist who, in 1935, made contact with Joaquín Torres-García and his constructive art project. Arden Quin settled in Buenos Aires in the early 1940s, helped create Arturo magazine, became involved with the Arte Concreto-Invención [Concrete Art and Invention] Movement, and was one of the founding members of the Arte Madí group. In 1948 he settled in Paris, where he showed his work at the Salon des Réalités Nouvelles. Arden Quin lived and worked in France for many years.Aldo Pellegrini (1903-1973) was a poet, playwright, essayist, art critic, and a moving force in Argentine cultural circles. He was an early promoter of Surrealism, and directed several publishing projects. He was also an active supporter and promoter of the various expressions of Abstract act, and provided encouragement to groups such as normal;">Artistas Modernos de la Argentina [Modern Artists of Argentina] and the Asociación Arte Nuevo [New Art Association].This essay appears in Artistas Abstractos de la Argentina [Abstract Artists of Argentina], a book by Pellegrini, who introduced the concept of Abstraction to Argentina; he explained that it was a way of expressing the change experienced by a cosmic way of seeing. He also pointed out that the artists represented in this book work in different styles — some are Concrete artists, others are exponents of Madí, and still others are independent artists who work in the field of Abstraction — but they all seek a similar goal of purity in their media and discipline in the execution of their work. A variety of opinions on the subject, written by other artists, can be found in: Las tendencias estéticas actuales y sus realizaciones plásticas [Current aesthetic trends and their expression in the visual arts] (document 742569); El orden y equilibrio constructivos inducen a un equilibrio [Constructive order and balance are conducive to a state of equilibrium] (document 742769), and La conquista de la invención concreta [The conquest of Concrete invention] (document 742729). This material was selected because it documents the artist's opinions on the elements that influence his poetic art.
