''Timaeus'' (; grc-gre, Τίμαιος, Timaios, ) is one of
Plato's dialogues, mostly in the form of long monologues given by
Critias and Timaeus, written 360 BC. The work puts forward reasoning on the possible nature of the physical world and human beings and is followed by the dialogue ''
Critias''.
Participants in the
dialogue include

, Timaeus,
Hermocrates, and
Critias. Some scholars believe that it is not the Critias of the
Thirty Tyrants who appears in this dialogue, but his grandfather, who is also named Critias. It has been suggested from some traditions (
Diogenes Laertius (VIII 85) from
Hermippus of Smyrna (3rd century BC) and
Timon of Phlius ( 320 – 235 BC)) that ''Timaeus'' was influenced by a book about
Pythagoras

Introduction

The dialogue takes place the day after Socrates described his ideal state. In Plato's works, such a discussion occurs in the ''
Republic''. Socrates feels that his description of the ideal state wasn't sufficient for the purposes of entertainment and that "I would be glad to hear some account of it engaging in transactions with other states" (19b).
Hermocrates wishes to oblige Socrates and mentions that Critias knows just the account (20b) to do so. Critias proceeds to tell the story of
Solon's journey to Egypt where he hears the story of
Atlantis, and how Athens used to be an ideal state that subsequently waged war against Atlantis (25a). Critias believes that he is getting ahead of himself, and mentions that Timaeus will tell part of the account from the origin of the

to man.
Critias also cites the
Egyptian priest in
Sais about long-term factors on the fate of mankind:
There have been, and will be again, many destructions of mankind arising out of many causes; the greatest have been brought about by the agencies of fire and water, and other lesser ones by innumerable other causes. There is a story that even you reekshave preserved, that once upon a time, Phaethon, the son of Helios

, having yoked the steeds in his father's chariot, because he was not able to drive them in the path of his father, burnt up all that was upon the earth, and was himself destroyed by a thunderbolt. Now this has the form of a myth, but really signifies a declination of the bodies moving in the heavens around the earth, and a great conflagration of things upon the earth, which recurs after long intervals.
The history of Atlantis is postponed to ''
Critias''. The main content of the dialogue, the exposition by Timaeus, follows.
Synopsis of Timaeus' account

Nature of the physical world

Timaeus begins with a distinction between the physical world, and the
eternal world. The physical one is the world which changes and perishes: therefore it is the object of opinion and unreasoned sensation. The eternal one never changes: therefore it is apprehended by reason (28a).
The speeches about the two worlds are conditioned by the different nature of their objects. Indeed, "a description of what is changeless, fixed and clearly intelligible will be changeless and fixed," (29b), while a description of what changes and is likely, will also change and be just likely. "As being is to becoming, so is truth to belief" (29c). Therefore, in a description of the physical world, one "should not look for anything more than a likely story" (29d).
Timaeus suggests that since nothing "becomes or changes" without cause, then the cause of the universe must be a
demiurge

or a god, a figure Timaeus refers to as the father and maker of the universe. And since the universe is fair, the demiurge must have looked to the eternal model to make it, and not to the perishable one (29a). Hence, using the eternal and perfect world of "
forms" or ideals as a template, he set about creating our world, which formerly only existed in a state of disorder.
Purpose of the universe
Timaeus continues with an explanation of the creation of the universe, which he ascribes to the handiwork of a divine craftsman. The demiurge, being good, wanted there to be as much good as was the world. The

is said to bring order out of substance by imitating an unchanging and eternal model (paradigm). The ''
ananke'', often translated as 'necessity', was the only other co-existent element or presence in Plato's
cosmogony. Later Platonists clarified that the eternal model existed in the mind of the demiurge.
Properties of the universe
Timaeus describes the substance as a lack of homogeneity or balance, in which the
four elements (

) were shapeless, mixed and in constant motion. Considering that order is favourable over disorder, the essential act of the creator was to bring order and clarity to this substance. Therefore, all the properties of the world are to be explained by the

First of all, the world is a ''living creature''. Since the unintelligent creatures are in their appearance less fair than intelligent creatures, and since intelligence needs to be settled in a soul, the
demiurge

"put intelligence in soul, and soul in body" in order to make a living and intelligent whole. "Wherefore, using the language of probability, we may say that the world became a living creature truly endowed with soul and intelligence by the providence of God" (30a-b).
Then, since the part is imperfect compared to the whole, the world had to be one and only. Therefore, the demiurge did not create several worlds, but a
single unique world (31b). Additionally, because the demiurge wanted his creation to be a perfect imitation of the Eternal "One" (the source of all other emanations), there was no need to create more than one world.
The creator decided also to make the perceptible body of the universe by four elements, in order to render it ''proportioned''. Indeed, in addition to fire and earth, which make bodies visible and solid, a third element was required as a mean: "two things cannot be rightly put together without a third; there must be some bond of union between them". Moreover, since the world is not a surface but a solid, a fourth mean was needed to reach harmony: therefore, the creator placed water and air between fire and earth. "And for these reasons, and out of such elements which are in number four, the body of the world was created, and it was harmonised by proportion" (31-33).
As for the figure, the demiurge created the world in the geometric form of a ''globe''. Indeed, the round figure is the most perfect one, because it comprehends or averages all the other figures and it is the most omnimorphic of all figures: "he

* He (letter), the fifth letter of many Semitic alphabets

considered that the like is infinitely fairer than the unlike" (33b).
The creator assigned then to the world a rotatory or ''circular movement'', which is the "most appropriate to mind and intelligence" on account of its being the most uniform (34a).
Finally, he created the
soul of the world, placed that soul in the center of the world's body and diffused it in every direction. Having thus been created as a perfect, self-sufficient and intelligent being, the world is a ''god'' (34b).
The creation of the world-soul
Timaeus then explains how the soul of the world was created (Plato's following discussion is obscure, and almost certainly intended to be read in light of the
''Sophist''). The demiurge combined three elements: two varieties of ''Sameness'' (one indivisible and another divisible), two varieties of ''Difference'' (again, one indivisible and another divisible), and two types of ''Being'' (or ''Existence,'' once more, one indivisible and another divisible). From this emerged three compound substances, intermediate (or mixed) Being, intermediate Sameness, and intermediate Difference. From this compound one final substance resulted, the
world-soul. He then divided following precise mathematical proportions, cutting the compound lengthways, fixed the resulting two bands in their middle, like in the letter
Χ (chi), and connected them at their ends, to have two crossing circles. The demiurge imparted on them a circular movement on their axis: the outer circle was assigned Sameness and turned horizontally to the right, while the inner circle was assigned to Difference and turned diagonally and to the left (34c-36c).
The demiurge gave the primacy to the motion of Sameness and left it undivided; but he divided the motion of Difference in six parts, to have seven unequal circles. He prescribed these circles to move in opposite directions, three of them with equal speeds, the others with unequal speeds, but always in proportion. These circles are the orbits of the
heavenly bodies
"Heavenly Bodies" is a song written by Elaine Lifton, Gloria Nissenson and Lee Ritenour, and recorded by American country music artist Earl Thomas Conley. It was released in May 1982 as the first single from the album '' Somewhere Between Right ...
: the three moving at equal speeds are the Sun, Venus and Mercury, while the four moving at unequal speeds are the Moon, Mars, Jupiter and Saturn (36c-d). The complicated pattern of these movements is bound to be repeated again after a period called a 'complete' or
'perfect' year (39d).
Then, the demiurge connected the body and the soul of the universe: he diffused the soul from the center of the body to its extremities in every direction, allowing the invisible soul to envelop the visible body. The soul began to rotate and this was the beginning of its eternal and rational life (36e).
Therefore, having been composed by Sameness, Difference and Existence (their mean), and formed in right proportions, the soul declares the sameness or difference of every object it meets: when it is a sensible object, the inner circle of the Diverse transmit its movement to the soul, where opinions arise, but when it is an intellectual object, the circle of the Same turns perfectly round and true knowledge arises (37a-c).
The elements
Timaeus claims that the minute particle of each element had a special
geometric shape

Timaeus makes conjectures on the composition of the four elements which some

thought constituted the physical universe: earth, water, air, and fire. Timaeus links each of these elements to a certain
Platonic solid: the element of earth would be a

and the 45-45-90 triangles. The faces of each element could be broken down into its component right-angled triangles, either isosceles or scalene, which could then be put together to form all of physical matter. Particular characteristics of matter, such as water's capacity to extinguish fire, was then related to shape and size of the constituent triangles. The fifth element (i.e. Platonic solid) was the
dodecahedron, whose faces are not triangular, and which was taken to represent the shape of the Universe as a whole, possibly because of all the elements it most approximates a sphere, which Timaeus has already noted was the shape into which God had formed the Universe.
The extensive final part of the dialogue addresses the creation of humans, including the
soul
In many religious and philosophical traditions, there is a belief that a soul is "the immaterial aspect or essence of a human being".

Later influence

The ''Timaeus'' was translated into Latin first by
Marcus Tullius Cicero around 45 BC (sections 27d–47b), and later by
Calcidius in the 4th century AD (up to section 53c). Cicero's fragmentary translation was highly influential in late antiquity, especially on Latin-speaking Church Fathers such as Saint
Augustine who did not appear to have access to the original Greek dialogue. The manuscript production and preservation of Cicero's ''Timaeus'' (among many other Latin philosophical works) is largely due to the works of monastic scholars, especially at
Corbie in North-East France during the
Carolingian Period.
Calcidius' more extensive translation of the ''Timaeus'' had a strong influence on medieval
Neoplatonic cosmology and was commented on particularly by 12th century Christian philosophers of the
Chartres School
During the High Middle Ages, the Chartres Cathedral established the cathedral School of Chartres, an important center of French scholarship located in Chartres. It developed and reached its apex during the transitional period of the 11th and 12t ...
, such as
Thierry of Chartres and
William of Conches, who, interpreting it in the light of the Christian faith, understood the dialogue to refer to a
creatio ex nihilo. Calcidius himself never explicitly linked the Platonic creation myth in the ''Timaeus'' with the Old Testament creation story in Genesis in his commentary on the dialogue.
The dialogue was also highly influential in Arabic-speaking regions beginning in the 10th century AD The ''Catalogue'' (fihrist) of
Ibn al-Nadīm provides some evidence for an early translation by
Ibn al-Bitriq (
Al-Kindī’s circle). It is believed that the Syrian Nestorian Christian
Ңunayn ibn Ishāq (809–873 AD) corrected this translation or translated the entire work himself. However, only the circulation of many exegeses of ''Timaeus'' is confirmed. There is also evidence of
Galen
Aelius Galenus or Claudius Galenus ( el, Κλαύδιος Γαληνός; September 129 – c. AD 216), often Anglicized as Galen () or Galen of Pergamon, was a Greek physician, surgeon and philosopher in the Roman Empire. Considered to be on ...
's commentary on the dialogue being highly influential in the Arabic-speaking world, with Galen's ''Synopsis'' being preserved in a medieval Arabic translation.
In his introduction to Plato's ''Dialogues'', 19th-century translator
Benjamin Jowett argues that "Of all the writings of Plato, the Timaeus is the most obscure and repulsive to the modern reader."
