Multidisciplinary Studies on Canvas Nature of Paintings at IFIN-HH Romania

Radiocarbon dating of pictorial support is usually less used. It is accepted for paintings with the estimated age older than the Stradivarius limit (ca. 1600 - 1650 CE) as stated by A.J.T. Jull in 1997, and not as an authentication method. Considering this, a seventeenth century oil-based painting (Main Case Study) is reported. Based on the results obtained as terminus post quem, the painting cannot be attributed to the famous painter from the classical period, considered to be the author, according to the signature. Two other recently solved cases (Sample 1 and Sample 2) are briefly recorded and the information obtained was used for a more accurate interpretation of the Main Case Study.
