Virgin and Child - V&A Museum, Cromwell Gardens, London, UK - Statues of Religious Figures on Waymarking.com

The Victoria and Albert Museum website tells us about the statue:

This seated Virgin appears to restrain the Christ Child’s movement by holding his right arm as he takes a step towards the viewer. It was a common practice for worshippers at a statue of the Virgin to kiss her foot. This may explain why the left foot is here extended and exposed.

The group is documented as being executed for the church of the Madonna dell' Arsenale, Venice, in 1578. When the church was demolished in 1809, it was transferred to the Scuola della Misericordia. It was bought by Sir John Leslie in 1878 and installed over a tablet bearing an inscription recording the trasfer. Girolamo Campagna was one of the major sculptors of his day in Venice, producing a large number of works in marble and bronze.

Wikipedia tells about the Virgin (Madonna) and Child:

The Madonna and Child or The Virgin and Child is often the name of a work of art which shows the Virgin Mary and the Child Jesus. The word Madonna means "My Lady" in Italian. Artworks of the Christ Child and his mother Mary are part of the Roman Catholic tradition in many parts of the world including Italy, Spain, Portugal, France, South America and the Philippines. Paintings known as icons are also an important tradition of the Orthodox Church and often show the Mary and the Christ Child. They are found particularly in Eastern Europe, Russia, Egypt, the Middle East and India.
