Francisco Pons Arnau was a Spanish Academic painter active in the mid 19th Century [Correction: late 19th, early 20th Centuries]. He became a follower of Joaquín Sorolla (see my recent post on Sorolla), and was influenced by Art Nouveau.
He painted portraits, figures, landscapes and what might be called intimate landscapes — garden scenes with detailed depictions of shrubs or trellised vines.
Beyond that, I’ve been able to find little information. Fortunately, there are several examples of his richly colored, light-filled paintings on the web.
