This painting is an anonymous copy of the 1773 painting by Vernet, which hangs in the Mauritshuis art museum in The Hague, Netherlands. The work's anonymity was common for the time, as aspiring artists often copied the painters they admired in order to study their technique. Vernet, one of the most celebrated French painters in his lifetime (1714-1789) and beyond, was known for his studies of dramatic skies over land and sea, and was often copied in both paintings and intaglio prints.
This unsigned oil is on an oak panel, the verso of which has been counter-mounted with linen.
