Career
He was a pupil of Giovanni Paolo Maggini in Brescia (c1610–1620) before he moved to Florence in c.1620 where he worked c.1620–1670. Sianis" instruments have a rather full arching, narrow purfling in very nicely channelled edges, and stiff f-holes. His scrolls show the influence of Maggini.
His work is very rarely met in the trade.
He is particularly well known for his violas. A viola by Valentino Siani is pictured in Italian Violinmakers by Walter Hamma.
