Hugo Demarco was an Argentinian-born French painter associated with the kinetic (op art) and Nouvelle Tendance movements. Demarco's work is concerned largely with color and movement and he often used prisms to reflect light and create movement. His work created "very active structures, in spite of the simplicity of their patterns" by using form, color, texture, and rhythm, including color degradation and chromatic contrasts, to create movement.



Bridget Louise Riley, an eminent English painter, has captivated the art world with her pioneering contributions to the Op Art movement. Born in London in 1931, Riley's early works were characterized by a figurative, semi-impressionist style. However, her artistic trajectory took a significant turn in the late 1950s and early 1960s when she began experimenting with optical illusions, leading to the development of her signature Op Art style. These works, utilizing geometric patterns in black and white, explored the dynamics of perception, creating disorienting effects and sensations of movement or color in the viewer.
Riley's exploration into color, which commenced in 1967, marked a new phase in her career. Her visit to Egypt in the early 1980s further enriched her palette, leading to the creation of works that reflected the vibrant hues of the Egyptian landscape. This period also saw the introduction of her 'Egyptian palette', which captured both the spirit of ancient and modern Egypt. Notable among her colorful works is "Cataract 3", where Riley utilized the contrast between warm and cold colors to produce a shifting, dynamic effect on the canvas, a testament to her continuous exploration of the interaction between form, color, and human perception.
Riley's work extends beyond canvas, with significant contributions to public art through murals. Her installations at prestigious institutions like the Tate, the Musée d'Art Moderne de la Ville de Paris, and the National Gallery, as well as a large-scale mural for the Chinati Foundation in Marfa, Texas, demonstrate her versatility and commitment to engaging with a broader public audience.
For collectors and experts in art and antiques, Riley's work represents a fascinating intersection of art, science, and perception, offering a unique visual experience that challenges and delights. Her dedication to expanding the boundaries of visual art ensures her place as a central figure in contemporary art discourse.

Bonaventura Francesco Cavalieri (Latin: Bonaventura Cavalerius) was an Italian mathematician and a Jesuate. He is known for his work on the problems of optics and motion, work on indivisibles, the precursors of infinitesimal calculus, and the introduction of logarithms to Italy. Cavalieri's principle in geometry partially anticipated integral calculus.


Ulrich Rückriem is a German sculptor known for his large-scale stone sculptures that are often displayed in public spaces. He studied at the Werkkunstschule Krefeld and the Kunstakademie Düsseldorf.
Rückriem's early work was influenced by the Minimalist movement, and he became known for creating abstract, geometric sculptures from raw stone blocks. He often works with granite, basalt, and other types of hard stone, using traditional carving techniques to shape and refine his forms.
In the 1970s, Rückriem began creating large-scale public installations, including his "Stone Alignments" series, which consists of rows of standing stones that evoke ancient megaliths and other prehistoric monuments. His work often engages with the natural environment, creating a dialogue between the man-made and the organic.
Rückriem has exhibited his work in museums and galleries around the world, including the Tate Gallery in London, the Solomon R. Guggenheim Museum in New York, and the Kunstmuseum Bonn in Germany. He has also received numerous awards and honors for his contributions to the field of sculpture, including the International Sculpture Prize in 1987 and the Praemium Imperiale in 2010.


Lucio Fontana was an Argentine-Italian artist known for his pioneering work in the field of Spatialism, an artistic movement that explored the relationship between space and art.
Fontana studied sculpture at the Academy of Fine Arts in Milan, Italy. In the 1940s, he began experimenting with a technique he called "Spatial Concept," in which he punctured or cut holes into the canvas to create a sense of depth and dimensionality.
Throughout the 1950s and 1960s, Fontana continued to explore the possibilities of Spatialism, creating works in a variety of media, including sculpture, ceramics, and painting. One of his most famous series of works is the "Tagli" (Cuts), which consist of monochromatic canvases with one or more slashes or punctures.
Fontana's work had a significant influence on the development of the Arte Povera movement in Italy, as well as on the development of Minimalism and Conceptual Art. He exhibited his work widely in Europe and the United States, and his legacy continues to be celebrated by artists and critics today.
Fontana's innovative approach to art and his exploration of the relationship between space and form continue to be a source of inspiration for artists working in a wide range of media.
