Las Meninas, (details) by Diego Velázquez, 1656.
The painting shows a large room in the Royal Alcazar of Madrid during the reign of King Philip IV of Spain, and presents several figures, captured, according to some commentators, in a particular moment as if in a snapshot. Some look out of the canvas towards the viewer, while others interact among themselves: the young Infanta Margaret Theresa is surrounded by her entourage of maids of honour ; just behind them, Velázquez portrays himself working at a large canvas. Velázquez looks outwards, beyond the pictorial space to where a viewer of the painting would stand.
In the background there is a mirror that reflects the upper bodies of the king and queen. They appear to be placed outside the picture space in a position similar to that of the viewer, although some scholars have speculated that their image is a reflection from the painting Velázquez is shown working on. Others speculate that Velázquez represents himself painting the Infanta Margaret Theresa, the King and the Queen just entering the room, causing the freezing of all the figures in their movements.
