what is the medium of the school of athens
School of Athens refers to a famous fresco painted by Raphael in the Apostolic Palace in Vatican City. The fresco was painted between 1510 and 1511 and is one of four frescoes painted by Raphael in the rooms now known as the Stanze di Raffaello. School of Athens was the second fresco completed in the room and depicts Raphael”s interpretation of philosophy as a branch of knowledge. Showing a gathering of Greek philosophers engaged in various activities, the fresco is considered a prime example of High Renaissance art and considered Raphael”s masterpiece.
School of Athens is one of a series of four frescoes painted by Raphael representing branches of knowledge. The frescoes, located on the walls of the Stanza, include images descriptive of philosophy, poetry, law, and theology. School of Athens is dedicated to philosophy as a path to knowledge, especially related to understanding causes to drive knowledge. All of the philosophers shown in the fresco traditionally sought knowledge through an understanding of root causes, tying back to the title and theme of the fresco. The overall theme of knowledge is integrated through Raphael”s frescos around the room but School of Athens is considered the best of the series.
Stanza della Segnatura
The Signature Room contains three of Raphael’s best known works – the School of Athens, the Parnassus, and the Disputation of the Holy Sacrament. Each wall represents one area of thinking: Theology, Poetry, Philosophy, and Justice, corresponding to the main fields of scientific knowledge. In the School of Athens, representing Philosophy, Plato and Aristotle are pictured at the centre of a group of other philosophers in a scene, set in Ancient Greece, which symbolizes the wisdom of classical antiquity. Arithmetic, Grammar, and Music are personified by certain figures: Geometry, Astronomy, Rhetoric and Dialectic by others. Above them is a majestic vaulted ceiling which may reflect Donato Bramante’s design for St Peter’s Basilica in Rome. It was not the first fresco painted in the Stanza della Segnatura – the room already contained decorations by the Early Renaissance artists Piero della Francesca (1415-92), Perugino (1450-1523) and Luca Signorelli (1445-1523), but Julius II decided that these paintings were expendable, and could be painted over.
The Victoria and Albert Museum in London has a rectangular version over 4 metres by 8 metres in size, painted on canvas, dated 1755 by Anton Raphael Mengs on display in the eastern Cast Court. 
The two figures to the left of Plotinus were used as part of the cover art of both Use Your Illusion I and II albums of Guns N’ Roses.
In the foreground, Pythagoras sits with a book and an inkwell, also surrounded by students. Though Pythagoras is well known for his mathematical and scientific discoveries, he also firmly believed in metempsychosis. This philosophy states that every soul is immortal, and upon death, moves to a new physical body. In this light, it makes sense that he would be placed on Plato’s side of the fresco.
The two main figures in the work are placed directly under the archway and in the fresco’s vanishing point, a compositional trick to draw the viewer’s eye to the most important part of the painting. Here, we see two men who effectively represent the different schools of philosophy—Plato and Aristotle.
One of whom is one of Plato’s masters, the Greek mathematician Pythagoras. Here he is demonstrating, his theory that ultimate reality consists of numbers and harmonic ratios.
On either side of Plato or Aristotle are the main thinkers of the classical world. The philosophers, poets and abstract thinkers are allied on Plato’s side. The physical scientists and more empirical thinkers are on the side of Aristotle. Only a few of the ancient thinkers in School of Athens can be identified definitely.
