ERNESTO BRIEL (1943-1992) Proyecto OP ART #2 India ink and graphite on card 14 1/4 x 16 5/8 in (36.2 x 42.3 cm) Executed circa 1980 Footnotes: This work is accompanied by a certificate of authenticity issued by the Estate of Ernesto Briel and signed by Jesús Selgas. Provenance Acquired directly from the artist's estate by the present owner. Proyecto OP ART #2 (1980) is a representative example of Ernesto Briel's sustained investigation into optical perception and geometric structure. The composition is organized around a hexagonal module that governs the visual field through repetition and mathematically precise line work, generating a perceptual vibration that actively engages the viewer. The contrast between the dark peripheral frame and the internal grid intensifies a sense of depth and illusory movement, situating the work within the traditions of Op Art and constructive abstraction. Rather than functioning as decorative pattern, the image operates as a perceptual system in which symmetry, repetition, and variation produce shifting optical effects. Executed in 1980, the work exemplifies Briel's conceptual and formal rigor, as well as his commitment to perception as a central artistic concern. A pioneering figure of Op Art in Cuba, Briel is recognized for his systematic approach to visual language and his contribution to the development of geometric abstraction. The work is documented in Ernesto Briel, The Rest in Silence (2022), underscoring its significance within his oeuvre.
