Rome, Italy, Triumph of Galatea detail. Fresco by Raphael ca. 1512 at the Loggia of Galatea in the Villa Farnesina.

Triumph of Galatea, ca. 1512. Artist: Raphael (1483-1520). The Loggia takes its name from the nymph Galatea frescoed by Raphael. Deep purple scales fall away like soft aquatic leaves from the flanks of the saffron coloured body of the bright handed triton, while his fiery face emerges from a mesh of algae; behind, the nymph’s back is nacreous and quivering. On the left the nude Nereid holds a burnished golden drape over her head in a classical gesture, which contrasts with the burnt tones of the hirsute triton.
The Villa Farnesina is a Renaissance suburban villa in the Via della Lungara, in the district of Trastevere in Rome.
The villa was built for Agostino Chigi, a rich Sienese banker and the treasurer of Pope Julius II. Between 1506–1510, the Sienese artist and pupil of Bramante, Baldassarre Peruzzi, aided perhaps by Giuliano da Sangallo, designed and erected the villa. The novelty of this suburban villa design can be discerned from its differences from that of a typical urban palazzo (palace). Renaissance palaces typically faced onto a street and were decorated versions of defensive castles: rectangular blocks with rusticated ground floors and enclosing a courtyard. This villa, intended to be an airy summer pavilion, presented a side towards the street and was given a U shaped plan with a five bay loggia between the arms. In the original arrangement, the main entrance was through the north facing loggia which was open. The villa became the property of the Farnese family in 1577 (hence the name of Farnesina).

Raffaello Sanzio da Urbino (April 6 or March 28, 1483 – April 6, 1520), known as Raphael, was an Italian painter and architect of the High Renaissance. His work is admired for its clarity of form, ease of composition, and visual achievement of the Neoplatonic ideal of human grandeur. Together with Michelangelo and Leonardo da Vinci, he forms the traditional trinity of great masters of that period.
