ENThe Lugano lake region numbers amongst the most important cradles of European art and architecture since the middle ages. The paths of itinerant masons, painters, builders, sculptors, architects and other diverse Lugano artists and artisans have left their traces throughout Europe. They made a particularly significant impact in the case of the Baroque style. Approximately 40 such individuals were active in the Grand Duchy of Lithuania during the period spanning the sixteenth through the eighteenth century. It has been argued most prominently by Polish art historian M. Karpowicz that their impact was crucial to the development of the specific Lithuanian architectural style of the eighteenth century termed the so-called Vilnius Baroque. The present article discusses hypotheses related to Guido Antonio Longhi and members of the Paracca family, who constitute the group of the most outstanding Lugano lake artists to contribute to the Vilnius Baroque. Keywords: Lugano lake artists, Vilnius Baroque, Daugava river region, Guido Antonio Longhi, Antonio Paracca, Francesco Paracca, Domenico Paracca. [From the publication]
