Sicurezza studied at the Academy of Fine Arts in Naples, winning a scholarship to fund his studies. He obtained a diploma in painting training under masters such as Carlo Siviero, Vincenzo Volpe, Vincenzo Migliaro and Paolo Vetri.
He moved to Formia in 1933–1934, when he was called to paint the chapel of St. Anthony in the church of Maranola. Here he met Virginia Mastrogiovanni whom he married in 1934.
In the hardest times of World War II he, his wife, and their four children, fled first into the mountainous caves in Coreno Ausonio, then through the warfront to Calabria. After the war, the family returned to Formia.
The war had destroyed and damaged the churches in the area, which held many of Sicurezzi's work. Among them were Angeli musicanti (Angels Playing Music), a fresco he painted for the chapel of Our Lady of Pompei and two oval portraits of Pope Leo XIII and Blessed Bartolo Longo.
The search for new altar pieces, replacing the ones destroyed, it is not easy for both the difficult economic situation and the clergy that requires religious representations in line with the traditional iconography, which the artist sometimes agrees not to foreclose future commissions.
When Antonio Sicurezza could finally express himself more freely, he had artistically valuable results, such as the works of the apse of St. John, St. Albina in the church of Saint Erasmus, and then, above all, the paintings of St. Francis and of the Annunciation at the church of Our Lady of Carmine and that of Saint Roch in Pico. It is valuable to note that the landscape behind the figures is represented in a deliberately simple manner, so that the faithful can recognize immediately the local sights and monuments, as in St. Albina and in St. Francis, in which it is particularly significant the view of the large Gaeta gulf.
In the summertime he worked outside to paint landscapes and alleys, while during the rest of year he worked in his studio mainly with charcoal and watercolors or tempera. He produced sketches and studies for religious themes or he painted still lives with immediacy and lightness.
After the summer of 1965 he left teaching and set up the large study that, among carob trees and prickly pears, he had built on the land of Santa Maria la Noce. It was now easier to prepare sketches and large cartoons for religious works and then – limiting the charcoal and pastel studies – he could systematically focus on oil painting, especially of the human figures and still lives.
In fact the style change, which made him prefer oil painting and saw the use of systematic and almost exclusive spatula instead of a brush, occurred in the late Fifties. Some of the paintings exhibited in Rome in July 1961, including two paintings that were awarded to the contemporary art exhibition held in Turin in the context of the events of Italy '61, already put in evidence the use of the spatula to illustrate the human figure and objects.
In the following years he devoted a greater commitment to personal and collective exhibitions, with a lack of direction, but without referring to a gallery or an agent and tied to a provincial reality. Despite this, he won several distinctions and awards, and news about him with reproductions of his works can be found in various catalogues of contemporary artists.
With advancing age, Antonio Sicurezza and his wife moved to the centre of Formia. The last house was more chaotic for the desire of finding the proper light for each painting. Yet, despite his age and disorder, the work was intense. To complete a painting he took around five sessions, which meant at least two new works every week. He worked both mornings and afternoons, often devoting first energies to harder works such as the naked human figures. In the living room the walls are covered with framed paintings, while others are simply placed in the corners. It is here that he received friends and admirers. It was during this period the groups of young people with musical instruments that the artist calls concerts, many nudes, vigorous still lives and some outside scenes were painted.
Exceptionally, in August 1978 Antonio Sicurezza did not go to Santa Maria Capua Vetere for the annual celebration of the Assumption. It was the beginning of the sickness that, a year later, August 29, 1979, brought the artist to die at the age of 74 years.
The background assumptions of Sicurezza's painting are based on values indispensable for him: the respect of human dignity and the sacredness of work. The artist continued to explore and experiment with constant application for many years to reach its capacity of synthesis in painting.
His style reaches maturity based on two fundamental elements: the physical construction of the subject, with increasing use of the spatula to distribute and overlay color, and the mention of the deliberately unfinished around the main theme. The result of all this is a subjective realism. Through the filter of the artist, the performance is careful and accurate for its main theme and the parties to which are assigned a significant role. The same performance is tempered and sometimes only mentioned in the rest of the composition.
Two other considerations must be made: color and atmosphere. Sicurezza manifests for the color a particular passion and he accepts difficult challenges. The atmosphere should be clarified as a physical fact: the atmosphere of the corner of the world where the painter lived and characterized by an extraordinary transparency and brightness, and in which the subjects of his paintings systematically lie, receiving security and serenity.
Antonio Sicurezza, in a century that profoundly transforms reality, puts himself stubbornly in the vein of realism. The artist, at once humble and stubborn, finds his formula of expression in ancient heritage but with original and modern execution.
"The result reached by Antonio Sicurezza is the result of his research, where the responsiveness of more accurate technical means resolves the discovery of the deeper meaning of reality. Therefore, an understanding that surpasses all interpretations animates his painting, to respect it in its entirety. For this reason, in its naked flesh, the more flesh it is, the more chaste" (Luigi Volpicelli).
Elio Marciano for the female nude observes that "the earthly reality of the fine figures of young girls is filled with love of classical perfection of chaste nudity." Guido Bernardi instead puts its focus on humble objects represented in the paintings of the painter, who, "with a wonderful insight figured object, is able to convey continuous points of joy and reflection".
Mario Lepore ascribes to the works of Antonio Sicurezza "the solidity of a job not only well known but also rich in resources and, most importantly, that shows a genuine temperament, from the narrative paintings skills. The quality of design and composition, sensitivity to color and light, reality probated but also poetically observed, often allow him to achieve beautiful accents".
Other critical interventions are often united by a thin thread that identifies values early in the artist and natural attachment to popular traditions, moral honesty, humility and frank simplicity.Still life
