Besides the royal seals, there have been also the nobles (boyars) seals on which the signs can be inspired by medieval bestiary (lions, eagles, griffins, snakes etc.) commonly reported but most fall within of the geometric type. Historically, the majority of seals were circular in design, although ovals, triangles, shield-shapes and other patterns are also known. The design generally comprised a graphic emblem (sometimes, but not always, incorporating heraldic devices), surrounded by a text (the legend) running around the perimeter. It should be noted that most of the seals to which we refer had heraldic character, even if sometimes the field mark is shown in the circular seal. About the multiple seals usage in the Romanian countries was established that it was inspired by the model of Latin Chancelleries of Poland andHungary. 

Seal impressions are found on all sorts of documents, from royal documents, letters and legal contracts to official permits, for seals had greater validity than signatures. Masterworks in miniature, the seals leave lasting impressions of the people who commissioned and used them, and the worlds in which they were created. Traditional wax seals continue to be used on certain high-status and ceremonial documents, but at the beginning of the 20th century they were gradually superseded in many other contexts by inked or dry embossed seals and by rubber stamps.
