The rhombus as an ornamental motif of traditional art can be found both among the signs sewn on popular costumes or in interior textiles, on household objects, and among the shapes found in traditional cuisine. Being a geometrical motif with an archaic symbolic charge, characterized by perpetuity and cosmic sacredness, it was exploited and integrated into all the daily, celebratory and ceremonial circumstances of man. In this context, the objective of the study was directed towards the presentation of the multicriteria interpretation of this motif. On the one hand, the Rhombus carries a special semantic load, varied by the chromatic diversity and by the shapes it takes, and on the other hand, the aim is to record and fix some valuable images of the objects bearing this decorative element. Noted for its wide use, the Rhombus is found in its geometric meaning as a singular element, in ensembles of motifs and geometric compositions integrated with other inscribed motifs, but also in free rendering that involves changes in outline and proportions. Thus, knowing the multiple values of the rhombus allows the revitalization of some compositions from the national folk art and the preservation of this ancient primary ornamental motif, while the aesthetic valences and spiritual interferences will serve as a source of inspiration for today’s folk art creators. The paper presents the results of the study carried out within the State Program 20.8009.0807.17 REVICULT.
