Mosaic of Minerva from Tusculum, 3rd century CE. The surrounding lunar phases were added at the time of installation in the Vatican Museum, 18th century.
The goddess is shown with the aegis, an abject which, according to Virgil “… Athene wears in her angry moods - a fearsome thing with a surface of gold like scaly snake-skin, and he linked serpents and the Gorgon herself upon the goddess’s breast—a severed head rolling its eyes.”
I Musei Vaticani (Vatican Museums) are located inside Vatican City, in Rome. They display an immense collection of works, as it has been built up by the Popes during the centuries. They are divided into 25 areas, among which the most famous are the Pinacoteca (The Picture Gallery) - with paintings by Rapahel, Leonardo da Vinci, Giotto, Perugino and Caravaggio - the Stanze di Raffaello (Raphael Rooms) - four rooms frescoed by Raffaello Sanzio and his novices, whose most famous fresco is La Scuola di Atene (The School of Athens) in the Stanza della Segnatura - the Musei di Antichità Classiche (Museums of Classical Antiquities) - museums of marble and bronze sculptures from Greek and Roman artists – and the most famous of all, the Cappella Sistina (Sistine Chapel), which is same room in which the cardinals elect the popes and is famous all over then world for the Guidizio Universale (the Last Judgement), a fresco by Michelangelo Buonarroti that covers a whole wall. The other walls and the vault have been frescoed as well by other great artists of the second half of the XV century, such as Sandro Botticelli Pinturicchio and Domenico Ghirlandaio.
