A priest anoints the head of a child. The paschal candle held by his companion indicates that it is Easter eve. The architecture is based on that of Sant'Atanasio dei Greci in Rome. This 16th-century church was built for the city's Byzantine community soon after the patriarch of Constantinople had adopted Catholicism's enumeration of the seven sacraments.
This is one of a series of paintings illustrating the sacraments painted for Poussin's Roman patron, Cassiano dal Pozzo.
