Monica Marioni was born near Treviso in 1972, but moved to the area of Vicenza when she was still very young, where she still lives several months of the year. She instinctively approached art during her studies, enrolling at the Vicenza Institute of Art; nevertheless, she obtained a degree in statistical sciences because of her passion for mathematics, a science in which she has found ample space for creativity.

She spent several years in a large industrial group, thereby developing strong ties with certain materials and the types of manipulation functional to them. This was translated in the dense material nature of her first abstract works, created on the most disparate supports, with a wealth of strong juxtapositions between metals, plastics, earth and resins, which she commanded through an intense manual action of selection and transformation. Her personal shows at Contarini-Fasan Palace in Venice and at Yvonne Artecontemporanea of Vicenza in 2007 were expressions of this phase.

Her continuous and intense experimentation rapidly led her to take action with respect to her own artistic magma, striking out on the road of progressive simplification and order, in observance of the principle according to which art is discipline. She thus elected the canvas as her sole medium, continuing to pursue material lightness and encountering figurative depiction, which she realised through a singular balance between collages and painting. This was the season of her personal shows in the United States, at the Carlo Livi Gallery of Miami and the Poltrona Frau Showroom of Washington D.C., both of which took place in 2008, and her shows in Rome, Capri and Vicenza, again, between 2008 and 2009. At the end of 2008 she won the First Prize of the Fiorino d'Oro for Painting, which was given to her in Florence, testifying to the fact that she had achieved great technical and expressive maturity in material on canvas, from which the stylistic elements of the highest Italian pictorial tradition emerge, with the strength of a contemporary and extremely personal re-interpretation. Her great personal show in 2009 at the Museo de Arte Italiana in Lima, within the Italy-Peru economic and cultural forum, inaugurated by the authorities of the two countries, was based on this important heritage.

In the summer of the same year, she was invited to realise a monumental work for Detournement Venise, a collateral event of the 53rd Biennale d'Arte of Venice, which offered her the opportunity to express her eclectic nature on a large scale: with no reverential fear, she realised "Ego", which was an initial trial installation and video art, in conjunction with a single work, designed to stimulate awareness of the duality of the human spirit. The success of this experience reinforced the artist's desire to express her research on the emotional dynamics of the contemporary individual, through the use of different "brushstrokes" than material on canvas. She thus came to "digital painting", a meeting point and point of equilibrium between photography and digital art; a further evolution, baptised by Anna Caterina Bellati in "Il vuoto e le forme", a collective exhibition that was a collateral event to the Biennale Architettura of Venice 2010, and was fully expressed in her recent personal exhibition Ninfe (Nymphs) in Vicenza, organised on the initiative of the Vignato Foundation for Art of Vicenza, by Oliver Orest Tschirky.
