"17th century school" is close to Cornelis van Poelenburgh
Cambi, from Italy, sells on 17 May 2017 a "School of the 17th century" landscape with nymphs and satyrs, estimated at 3,000 to 3,500 Euro.
It is a work from the School of Cornelis van Poelenburgh (1586-1667), who painted many similar vaguely mythological works with nymphs, satyrs, ... without a real story behind them.
Another (better) version of the same painting is given to van Poelenburgh (on Pinterest) with a date in the 1620s, but I know nothing more about it. The value depends on how close the work is to Van Poelenburgh, I would guess that it is not by him but by his studio or a close follower, and that the estimate is about right.
