Fresco is a technique of mural painting executed upon freshly laid ("wet") lime plaster. Water is used as the vehicle for the dry-powder pigment to merge with the plaster, and with the setting of the plaster, the painting becomes an integral part of the wall. The word fresco is derived from the Italian adjective fresco meaning "fresh", and may thus be contrasted with fresco-secco or secco mural painting techniques, which are applied to dried plaster, to supplement painting in fresco. The fresco technique has been employed since antiquity and is closely associated with Italian Renaissance painting.
Galatea is an ancient Greek name meaning "she who is milk-white".
Polyphemus is the one-eyed giant son of Poseidon and Thoosa in Greek mythology, one of the Cyclopes described in Homer's Odyssey. His name means "abounding in songs and legends", "many-voiced" or "very famous". Polyphemus first appeared as a savage man-eating giant in the ninth book of the Odyssey. The satyr play of Euripides is dependent on this episode apart from one detail; Polyphemus is made a pederast in the play. Later Classical writers presented him in their poems as heterosexual and linked his name with the nymph Galatea. Often he was portrayed as unsuccessful in these, and as unaware of his disproportionate size and musical failings. In the work of even later authors, however, he is presented as both a successful lover and skilled musician. From the Renaissance on, art and literature reflect all of these interpretations of the giant.
Raffaello Sanzio da Urbino, now generally known in English as Raphael, was an Italian painter and architect of the High Renaissance.

Together with Leonardo da Vinci and Michelangelo, he forms the traditional trinity of great masters of that period.
Il Sodoma was the name given to the Italian Renaissance painter Giovanni Antonio Bazzi.

Sebastiano del Piombo was an Italian painter of the High Renaissance and early Mannerist periods famous as the only major artist of the period to combine the colouring of the Venetian school in which he was trained with the monumental forms of the Roman school. He belongs both to the painting school of his native city, Venice, where he made significant contributions before he left for Rome in 1511, and that of Rome, where he stayed for the rest of his life, and whose style he thoroughly adopted.
Acireale is a coastal city and comune in the north-east of the Metropolitan City of Catania, Sicily, southern Italy, at the foot of Mount Etna, on the coast facing the Ionian Sea. It is home to numerous churches, including the Neo-Gothic St. Pietro's Basilica, St. Sebastiano's Basilica in the Sicilian Baroque style, and the 17th century Acireale Cathedral, and a seminary, for the training of priests.

The Chigi Chapel or Chapel of the Madonna of Loreto is the second chapel on the left-hand side of the nave in the Basilica of Santa Maria del Popolo in Rome.

The chapel is a treasure trove of Italian Renaissance and Baroque art and is ranked among the most important monuments in the basilica.
Baldassare Tommaso Peruzzi was an Italian architect and painter, born in a small town near Siena and died in Rome. He worked for many years with Bramante, Raphael, and later Sangallo during the erection of the new St. Peter's. He returned to his native Siena after the Sack of Rome (1527) where he was employed as architect to the Republic. For the Sienese he built new fortifications for the city and designed a remarkable dam on the Bruna River near Giuncarico. He seems to have moved back to Rome permanently by 1535. He died there the following year and was buried in the Rotunda of the Pantheon, near Raphael.

It is especially famous for the rich frescos by Raphael and other High Renaissance artists that remain in situ.
The Birth of Venus is one of the most famous paintings by 19th-century painter William-Adolphe Bouguereau. It depicts not the actual birth of Venus from the sea, but her transportation in a shell as a fully mature woman from the sea to Paphos in Cyprus. She is considered the epitome of the Classical Greek and Roman ideal of the female form and beauty, on par with Venus de Milo.
The Loves of the Gods is a monumental fresco cycle, completed by the Bolognese artist Annibale Carracci and his studio, in the Farnese Gallery which is located in the west wing of the Palazzo Farnese, now the French Embassy, in Rome. The frescoes were greatly admired at the time, and were later considered to reflect a significant change in painting style away from sixteenth century Mannerism in anticipation of the development of Baroque and Classicism in Rome during the seventeenth century.
The School of Athens is a fresco by the Italian Renaissance artist Raphael. It was painted between 1509 and 1511 as part of a commission by Pope Julius II to decorate the rooms now called the Stanze di Raffaello in the Apostolic Palace in Vatican City.

Venus Anadyomene is one of the iconic representations of the goddess Venus (Aphrodite), made famous in a much-admired painting by Apelles, now lost, but described in Pliny's Natural History, with the anecdote that the great Apelles employed Campaspe, a mistress of Alexander the Great, for his model. According to Athenaeus, the idea of Aphrodite rising from the sea was inspired by the courtesan Phryne, who, during the time of the festivals of the Eleusinia and Poseidonia, often swam nude in the sea. A scallop shell, often found in Venus Anadyomenes, is a symbol of the female vulva.
Acis and Galatea are characters from Greek mythology later associated together in Ovid's Metamorphoses. The episode tells of the love between the mortal Acis and the Nereid (sea-nymph) Galatea; when the jealous Cyclops Polyphemus kills Acis, Galatea transforms her lover into an immortal river spirit. The episode was made the subject of poems, operas, paintings, and statues in the Renaissance and after.
La Fábula de Polifemo y Galatea, or simply the Polifemo, is a literary work written by Spanish poet Luis de Góngora y Argote. The poem, though borrowing heavily from prior literary sources of Greek and Roman Antiquity, attempts to go beyond the established versions of the myth by reconfiguring the narrative structure handed down by Ovid. Through the incorporation of highly innovative poetic techniques, Góngora effectively advances the background story of Acis and Galatea’s infatuation as well as the jealousy of the Cyclops Polyphemus.

This is the only sculpture that Raphael himself designed and was executed according to his intentions.
