The painting of María Antonia Dans, sometimes described as a "naif" is, in reality, a neo expressionism root deliberately ingenuista, emparentable with modes of embroidery people, root barroquista. His landscapes are elemental, with something of a mosaic. The work in the field, the world of the sea, are those with a reference to sweet and as a child, in their very hot and contrasted, in which abound the carmines, green glittering, blue, pure, the yellow ones. The material is thick and in the drawing there is as a break in the line, pretending to be an insistence of imaginary clumsiness that ultimately does nothing but add grace, delight, this peculiar and unmistakable expression plastic. Nothing could be further from the paint Mª Antonia Dans that any show of grandiloquence. On the contrary, the emotionalism, the maximum simplicity, the bucolic, including chairing a task is deliberately limited in the theme and yet so rich, so there is a flowering of variations. When we look at this painting it seems that ahondamos in the attic of our memory, to find the most happy moments of childhood. One would like to inhabit the worlds of this painting and be installed forever on them, because they are brimming with sweet kindness. -Areán, Carlos-Antonio: Young figuration in Spain.
