In the first two decades of the 18th century, Cristoforo Tasca (Bergamo, 1661 – Venice, 1735) produced numerous artworks for Rijeka, Krk, and Karlobag. His oeuvre has now been complemented by a signed and dated altarpiece from 1725 at the main altar of the Collegiate, today a parish church in Rijeka. The author elucidates the complex circumstances behind the construction of the main marble altar and the role of its donators, the Orlando family, who created the altar iconography as directly related to the family’s patron saints. Based on the last will of Giovanni Michele Androcha from 1728, the pres- ence of painter Cristoforo Tasca in Rijeka has been confirmed for the first time in a written document. A painting of the Annunciation, which originates from the former Benedictine monastery of St Rochus in Rijeka and is today preserved in the Benedictine monastery of San Daniele in Abano Terme near Padua, has been likewise attributed to Tasca. The second part of the article focuses on artworks that have been newly attributed to the Venetian painter Giovanni Battista Augusti Pitteri (Venice, between 1691 and 1695 – Zadar ?, after 1759 ?), who moved to Zadar around 1730 and left a major opus in Dalmatia. Before 1730, a large painting of the Baptism of Christ was made for the parish church of San Martino in Burano, attributable to Pitteri. Another artwork discussed in the article is the anonymous signed painting of the Virgin with the Child and Saints from the Franciscan Church of St Anne in Koper.
