Mirepoix (cuisine)
Similar flavour bases include the Italian "soffritto", the Spanish "sofrito", "refogado/sufrito" (braised onions, garlic and tomato) from Portuguese-speaking nations, the German "suppengrün" (leeks, carrots and celeriac), the Polish "włoszczyzna" (leeks, carrots, celery root and parsley root), the US Cajun / Creole holy trinity (onions, celery and bell peppers), and possibly the French "duxelles" (mushrooms and often onion or shallot and herbs, reduced to a paste).
Holy Trinity (Masaccio)
The "Trinity" is noteworthy for its inspiration taken from ancient Roman triumphal arches and the strict adherence to recently developed perspective techniques, with a vanishing point at the viewer's eye level, so that, as Vasari describes it"a barrel vault drawn in perspective, and divided into squares with rosettes that diminish and are foreshortened so well that there seems to be a hole in the wall." This artistic technique is called "trompe l'oeil", which means "deceives the eye," in French. The fresco had a transforming effect on generations of Florentine painters and visiting artists. The sole figure without a fully realized three-dimensional occupation of space is the majestic God supporting the Cross, considered an immeasurable being. The kneeling patrons represent another important novelty, occupying the viewer's own space, "in front of" the picture plane, which is represented by the Ionic columns and the Corinthian pilasters from which the feigned vault appears to spring; they are depicted in the traditional prayerful pose of donor portraits, but on the same scale as the central figures, rather than the more usual 'diminution', and with noteworthy attention to realism and volume.
