As recognized by Ann Percy in 1968 (see Bibliography), the present sheet comes from an album of drawings by Castiglione and his workshop possibly assembled in the 18th century and now dismembered. Numbered in old ink at bottom center in an easily recognizable, spidery hand, sheets from this album are more or less consistent in size (approximately 40 x 25/30 cm). Many of the drawings from the album are landscape studies, including two in the Achenbach collection (1963.24.114-115). They are particularly interesting as they show an emphasis on landscape for its own sake that is unique in Castiglione's graphic oeuvre. These sheets are executed with a nervous, dashingh stroke which frequently turns into an almost calligraphic scrawl. The sheets are difficult to date, as they show no direct relation to Castiglione's painted or printed work, but can be dated around the artist's stay in Rome in the 1640s, where he would not doubt have found numerous stimuli for his interest in landscape.
