The Dying Gaul (in Italian: Galata Morente), better known as the Dying Galatian or the Dying Gladiator, is an ancient Roman marble copy of a lost Hellenistic sculpture that is thought to have been executed in bronze, which was commissioned some time between 230 BC and 220 BC by Attalus I of Pergamon to celebrate his victory over the Galatians in Anatolia.

The Borghese Gallery (Italian: Galleria Borghese) is an art gallery in Rome, Italy, housed in the former Villa Borghese Pinciana. It is a building that was from the first integral with its gardens, nowadays considered quite separately by tourists as the Villa Borghese gardens. The Galleria Borghese houses a substantial part of the Borghese collection of paintings, sculpture and antiquities, begun by Cardinal Scipione Borghese, the nephew of Pope Paul V (reign 1605–1621).

The Loggia dei Lanzi, also called the Loggia della Signoria, is a building on a corner of the Piazza della Signoria in Florence, Italy, adjoining the Uffizi Gallery. It consists of wide arches open to the street, three bays wide and one bay deep. The arches rest on clustered pilasters with Corinthian capitals. The wide arches appealed so much to the Florentines, that Michelangelo even proposed that they should be continued all around the Piazza della Signoria.
