Abstract
In the Collection of Prints and Drawings of the National Gallery in Prague the author has discovered a forgotten drawing which remained unpublished thus far. It can be classified among the drawings by Gregorio de Ferrari (1647-1726) who decorated the "gallery" in Palazzo Balbi-Senarega in Genoa.
The subject matter of the ceiling fresco there is called "The Triumph of Love". Gregorio de Ferrari produced several preparatory designs for the entire figural composition of this ceiling fresco.
The newly published Prague drawing, which is a compositional study for it, features the central motif of the fresco, specifically the figures of Bacchus and Ariadne. Based on the stylistic analysis, the drawing in The National Gallery in Prague was dated to the late 1680s or early 1690s.
