Oil on canvas, en brunaille, in a period frame, 46cm by 28cm.
The term en brunaille, was coined in early 17th Century France to describe paintings depicted in various shades of brown.
Its roots were in the early 12th Century when the stained glass in Cistercian monasteries, like other art forms, were not allowed to display any colour.
This is one of the few 18th Century Italian paintings in the Collection and was acquired in 1891 by William Alleyne, 3rd Marquess of Exeter (1825-1895).
Tiepolo is widely considered to be one of the greatest Venetian artists of the 18th Century.
He achieved success early in his long career, and was prolific, working not only in Italy, but also receiving major commissions in Germany and Spain.
