This painting is a scene from the mythology of Ancient Greece and Rome.
Mythology is the collection of stories about the gods, heroes and traditions specific to nations or cultures.
Apollo is the god of the sun and appears in the painting on the left with a light around his head.
Apollo visits Vulcan at his forge.
The forge is a shop where people make metal objects.
Vulcan is the god of fire who always worked at the forge.
Vulcan was married to Venus, the goddess of love.
Apollo tells Vulcan that Venus is unfaithful to him with Mars, the god of war.
Vulcan makes an angry face, and the workers at the forge look surprised.
They all stare at Apollo when he tells Vulcan of the infidelity of his wife.
Velázquez created paintings that told a story, for example, this visit of Apollo to Vulcan.
The scene is lively and reflects the surprise that comes with the news.
For this reason, Velázquez portrays the figures with diverse gestures and reactions.
