Focus on this artwork and explain the abstract.
The Equestrian Portrait of Charles I (also known as Charles I on Horseback) is a large oil painting on canvas by Anthony van Dyck, showing  Charles I on horseback.  Charles I had become King of England, Scotland and Ireland in 1625 on the death of his father James I, and Van Dyck became Charles's Principal Painter in Ordinary in 1632.
The portrait is thought to have been painted in about 1637–38, only a few years before the English Civil War broke out in 1642. It is one of many portraits of Charles by Van Dyck, including several equestrian portraits. It is held by the National Gallery, London.
