The Hireling Shepherd, by William Holman Hunt, was painted in 1851; and it is currently housed in the Manchester City Art Gallery. This oil on canvas was initially controversial due to its vulgar and coarse subject matter. The painting depicts a shepherd who is neglecting his flock in favour of an attractive country girl; a noticeable display are the sheep who carelessly wander into a field of corn. Hunt intended the picture as a rebuke to the Church for its inability to provide a proper moral guidance. The couple symbolizes the distraction and the lack of sense of duty among the Christians. The atmosphere is rustic and strongly naturalistic with the artist’s use of bright and intense colours. The subject of William Holman Hunt's The Hireling Shepherd was actually taken from William Shakespeare's King Lear, in the play Shakespeare’s song represents an irresponsible shepherd.
