Signed on the bottom right J. Roos. "His family emigrated to Amsterdam because of the war of thirty years in 1640. He was a student of Guilliam du Gardijn, Cornelis de Bie and Barent Graat, but the landscape painters Nicolaes Berchem and Karel Dujardin had the greatest influence on He. In 1653 the Roos family returns to Germany, where Johann and his brother Theodor Roos work together on a commission for a cloister in Mainz. Between 1654 and 1659, Johann works for Ernst, Landgrave by Hesse-Rheinfels (son of Maurice , he lived between 1623 and 1693), where he painted a portrait of a Prince (1654, Heidelberg, Kurpfälzisches Museum) and religious scenes. In 1664 he is invited to paint to the Court of Carlo I Luigi, Elector Palatine. Due to the conditions of unsatisfactory work, moved with the family to Frankfurt in 1667, where it has a lot of success, but loses everything in a calder in 1685. The painting in question seems to be the best he could express the painter, when Vouls represent that union of men and animals in idyllic harmony with nature - this was his thinking he aspired to give his representatures a realistic imprint, especially in the Agresti scenes and animal representations. In this case, there is a sense of intimate flavor, almost familiar, which globalizes in a harmonizing landscape union, and therefore nature, men and animals. If we were induced to a comparison with his son Philipp Peter, we could say that he remains much more humoral and intimist in the search for a link with the whole, and less theatrical nature, almost not to be emphasizing as the son, who often adopts in the forefloor Scenes of animals and almost retracting depicorations of them.
