There's something ephemeral and poetic about small sketches like these. They don't usually come with a Name. But the draughtsman who safeguarded these views in his traveling sketchbook, probably drawing from nature, certainly was a highly skilled master of his craft. 

Establishing the authorship of the present pair of drawings, which can be dated to around 1600, has proved impossible as of yet. As their size would suggest, they are most probably loose sheets from a sketchbook, swiftly drawn as a memento or a quick exercise. According to Stefaan Hautekeete, curator of drawings at the Belgian Royal Library, they are thematically and stylistically related to drawings by the Flemish draughtsman Hans Bol from the 1580’s, though the somewhat looser and freer hand seen here would suggest a slightly later date of creation. Many artists from the circle of Bol, such as Hendrick Gysmans, Frans Boels, Jacob Savery of Jacob Grimmer, come to mind as possible authors. Even Roelant Savery has been suggested as the creator, as his “Rocky Bohemian Landscape” (dated 1603) kept in Bruges shows some similarities to the present work. However, as the drawn oeuvre of all these artists has not yet been studied in depth, narrowing the attribution down further is difficult.
