It is difficult to pinpoint exactly where one can view works by Agostino Tassi. Many museums and collections around the world hold paintings; however, without a catalogue raisonné or collection list, it is impossible to say which ones have works by Tassi. Furthermore, many paintings are not on public display. They may be in storage or on loan. Museums also regularly rotate their displays. Paintings may come and go from view. If you are planning to view a specific painting, it is always best to check with the museum in advance. Paintings by Nicolas Poussin, for example, can be found in the Musée Fesch (Ajaccio, Corsica), the Baltimore Museum of Art, the Palace of the President of Yugoslavia (Belgrade), Belvoir Castle (Leicestershire), the Staatliche Museen (Berlin, East and West), the Barber Institute of Fine Arts, University of Birmingham (England), the Museum of Fine Arts (Boston), and the Musée des Beaux-Arts (Caen).

Agostino Tassi is mainly known as a painter, but he was also active as a printmaker. Information about his prints is scarce, but context can be derived from the activities of his contemporaries. In the early 17th century, many artists travelled to Rome to study classical art. Pietro Testa, for example, arrived in Rome around 1628^[2] and copied works by Raphael, Polidoro da Caravaggio, and ancient sculptures. Testa was employed by Joachim von Sandrart to make drawings for engravings of ancient statues in the collection of Marchese Vincenzo Giustiniani. These engravings were published in two volumes titled Galleria Giustiniana. Other artists working on this project included Cornelis Bloemaert, Renier Persin, Theodor Matham, Michael Natalis, and Claude Mellan. This project suggests a vogue for collecting and documenting classical art through prints.

Agostino Tassi (1580^[2]-1644^[2]) was an Italian^[2] painter of the early Baroque period, active mainly in Rome and Genoa. Although not as widely known as some of his contemporaries, Tassi's importance lies in his influence on other artists, particularly as the teacher of Claude Lorrain. Tassi specialised in painting *quadratura*, illusionistic architectural paintings, and seascapes. These skills were highly sought after for decorating palaces and villas. His frescoes can be seen in the Palazzo Pamphilj and the Villa Lante in Rome. His ability to create convincing illusions of depth and space was innovative for the time. Beyond his artistic skills, Tassi's life was marked by controversy. He was accused of raping Artemisia Gentileschi, a fellow painter. The trial and its scandalous details have made Tassi a figure of interest in studies of gender and power in the art world. While his paintings continue to be studied for their artistic merit, his biography offers insight into the social dynamics of seventeenth-century Italy.

Agostino Tassi was an Italian^[2] painter of the Baroque period, active mainly in Rome and specialising in architectural interiors and marine subjects. The additive process involves modelling a form from a soft substance, such as clay, plaster, or sculptor’s wax, before it is cast into bronze. Casting is completed in a foundry by specialist craftsmen; the artist usually oversees this part. Bernini’s studio used gesso, a white mixture of animal glue and chalk, as a priming and smoothing layer before gilding or painting a terracotta. Bole, a paint-like mixture of animal glue, iron oxide, and clay, was applied over smoothed gesso. It provided a secure surface for metal leaf, allowing it to withstand burnishing. Water gilding involves the gilder reactivating the adhesive in the bole with hot water, then applying the metal leaf using a wide, flat brush. Once firm, the gilder burnishes it with an agate stone or an animal tooth. Oil gilding could be applied over gesso or directly to the raw terracotta. It cannot be burnished; the surface therefore has a matte appearance, without the sheen of water gilding. Cloth wrapped around the fingers could smooth the clay. Used damp, it produced a softer, smoother appearance.

Agostino Tassi's influence is most clearly seen in the work of Artemisia Gentileschi, daughter of Orazio Gentileschi. Artemisia, herself a gifted and successful painter, was raped by Tassi. Orazio Gentileschi, once a close acquaintance of Caravaggio, was one of the few artists from that circle to achieve significant artistic merit. He eventually became a court painter for Charles I, dying in London in 1639^[2]. Other artists, such as Mario Minniti and Cecco Boneri, who were close to Caravaggio, failed to leave a notable mark on art history. Giovanni Baglione, despite being Caravaggio's adversary and biographer, secured commissions from popes, princes, and aristocrats, but is primarily remembered for his connection to Caravaggio. Annibale Carracci, influenced by Titian, initiated the Baroque style in Rome alongside Caravaggio. His frescoes in the Palazzo Farnese, begun in 1597, had a considerable influence on European art during the sixteenth century.

Agostino Tassi's artistic development occurred in a milieu where artists routinely studied and emulated the masters. Students gained "an easy habitude" by imitating the invention and manner of admired artists. The Romans, Venetians, Parmesans, and Bolognese were considered exemplary. Raphael was admired for his gift of invention and natural grace; Michelangelo, for his powerful design. Giulio Romano revealed the "sacred mysteries of Apollo" in his poetry of painting. Correggio excelled in broad lights and delicate colour, while Titian mastered colour harmony. Annibale Carracci assimilated the excellencies of all these artists. Nicolas Poussin, arriving in Rome at 30, felt his training lacking and essentially went back to school. He studied anatomy, geometry, and perspective, drawing from models in the studios of Domenichino and Andrea Sacchi. Poussin was deeply affected by the art around him, including antiquity and masters such as Raphael, Michelangelo, and Titian. He was also influenced by the Carracci and, despite ignoring Michelangelo and Caravaggio, was particularly drawn to Domenichino's *Flagellation of St Andrew*.

Agostino Tassi is best known for his skill in perspective and quadratura, a form of illusionistic painting that creates the impression of extended space. Although he produced independent paintings, he frequently collaborated with other artists, providing the architectural framework for their compositions. A prime example of Tassi's quadratura is his work in Guercino's fresco *Aurora* (1621^[2]) at the Casino Ludovisi in Rome. Tassi created the feigned architectural settings, which, combined with Guercino's figures and a *di sotto in sù* (seen from below) viewpoint, make the ceiling seem to open up to the sky. The fresco, commissioned by Cardinal Ludovico Ludovisi to celebrate his uncle's election to the papacy, depicts Aurora, goddess of the dawn, in her chariot. The illusion is so convincing that the painted architecture appears to extend the room's actual architecture.

Agostino Tassi was an Italian^[2] painter of the Baroque period (roughly, the early 17th to mid-18th century). The Baroque style, which first appeared in Italy, is typified by dynamism and movement. Baroque artists aimed to replace the ordered coherence of the Renaissance with more energetic compositions. Painters such as Peter Paul Rubens, who lived in Italy from 1600^[2] to 1608, developed techniques of Baroque movement. Rubens would build compositions around a dynamic spiral line, a 'line of force' that gives vitality to the whole picture. Figures twist and turn; even draperies flow. Italian artists reached an equivalent stage in the 1620s; Bernini's sculptures, for example, have a similar thread of energy and three-dimensional conception.
