As artists, Zóbel and Chillida began to develop in a sort of isolation and in a problematic context. In the early 1950s Chillida conceived his first sculptures in plaster and stone, which would later result in works like Lurra 16 (Earth 16) (1978), Lurra G-326 (Earth G-326) (1995) andLurra M-20 (Earth M-20) (1995), which conserve and rethink the corporeality and the folding of forms characteristic of those early figures. Meanwhile, Zóbel was concurrently moving between figuration and abstraction after witnessing the development of abstract expressionism.
Following his discovery of Rothko’s work in 1955, Zóbel reduced the content of his pictures to the essential, in compositional and thematic terms as well as in the use of colour. This would give rise to the Saetas (Arrows) paintings and to his first paintings with a limited colour palette, known under the generic title of Serie Negra (BlackSeries), of which some of the works on display, such as Aquelarre (Witches’ Sabbath) (1961) or Segovia II (1962), form part. Alfonso de la Torre notes that “In the Saetas Zóbel appears to concur with Chillida as to the heightened script-like stroke of black on the canvas, the two of them orienting their researches towards a certain mark-making that our consciousness attempts to comprehend, the rhythm of its unfolding. […] They can be understood as visual chords that waver between levity and gravity, in movement.” It was Zóbel’s definitive shift towards abstraction.
The Hispanic-Filipino artist evolved towards the study of light and the evocation of memory, both his own and that of the spectator. Zóbel himself explained that “essentially I’m speaking of light, of large forms and small forms, of what is far and what is near. Above all I think I speak of memories.”The works of this second period are characterized by the reintroduction of colour—now symbolic—which constitutes the basis for the construction of the painting. In pictures like Canción protesta III (Protest Song III) (1968) we can see how the forms emanate from their coloration, becoming increasingly blurred until they blend into the background, in ever lighter and more neutral tones, which would eventually give rise to the so-called Serie Blanca (White Series), to which works like La plazoleta (The Little Square) (1975) pertain.
Light was also one of the principal themes in the works of Chillida. In his case his works are plays of matter and void in which light comes into being, assumes its importance and turns into a generator of spaces and volumes. As well as the Lurras, see such works in steel as Yunque de sueños XIX (Anvil of Dreams) (1998), Besarkada V (Embrace V) (1991) or the bronze Hierros de temblor III (Trembling Irons III) (1957). Without a doubt, the handling of this light and the delicacy of their creations means that the works of both artists have a high poetical value.
According to the director of the gallery, Jordi Mayoral, “not only is this exhibition an original dialogue between two artists of great relevance in postwar art, it is an encounter of ‘crisscrossing paths’ that render the project exceedingly attractive and exceptional.” In that sense, the curator concludes the meeting of the two artists in 1964 thanks to Zóbel’s wish to include the sculpture Abesti Gogorra IV (Rough Chant IV), one of Chillida’s seminal works, in the collection of art on show in the Museo de Arte Abstracto Español was a moment of “mutual admiration, the feeling of having known each other forever, friendship, a fondness for poetry, a way with words, a eulogizing of the East”.
