Predominantly a landscapist, he produced two major rounds of themes, Boats and Corfu, in which the presence of humans is as discreet as unobtrusive a life the painter led. As early as 1939, i.e. remarkably early by Greek standards of the time, he proposed the first abstract renderings, inclined toward Kandinsky, but also indicative of Ventouras's realistic starting point, i.e. representational imaging. In the mid-fifties, he used color in his chalcographies, a color that was detached and disengaged from the outlines, until it reached explosive expressionist forms (Procession). His work displays a sense of internal unity and integration.
