In 1987 the Old Masters Collection was founded at the Maritime and History Museum of the Croatian Littoral in Rijeka, com- prising about one hundred and thirty paintings. It mainly consists of artworks once belonging to prominent Rijeka families that were acquired during the 19th and early 20th centuries. Only a smaller portion of the Collection came from the city’s religious institutions. These are all works of relatively modest artistic quality, thus the initial research revealed that quite a few were made after prints or more or less famous paintings. Since no systematic study of these models has hitherto been conducted, a number of questionable attributions and dates of execution concerning the paintings belonging to the Col- lection was proposed during the last decade of the 20th century. As far as the 17th-century paintings are concerned, the author has identified models for the paintings representing the Annunciation, Our Lady of the Rosary, the Marriage at Cana, the Adoration of the Shepherds and the Flagellation of Christ. The Annunciation was inspired by a print executed by Giovanni Jacopo Caraglio (Verona, ca. 1505 – Krakow, 1565) or its later derivation, while Our Lady of the Rosary was made after a print by Domenico Maria Canuti (Bologna, 1626-1684). The Marriage at Cana was painted after an engraving by Giovanni Battista Vanni (Florence/Pisa, 1599 – Florence, 1660) dating in 1637 or one of its later derivations. The engraving was, in its turn, made after the famous painting by Veronese (Verona, 1528 – Venice, 1588) exhibited today at the Louvre, while the Adoration of the Shepherds was made after an engraving by Jan (I) Sadeler (Brussels, 1550 – Venice, 1600). The Flagellation of Christ is a combination of a print of the same title and one depicting the Mocking of Christ. Both are work of Jan (I) Sadeler or by his copyist.
