Timaeus (dialogue) in the context of "Cube"

In semiotics, khôra (also chora; Ancient Greek: χώρα) is the space that gives a place for being. The term has been used in philosophy by Plato to designate a receptacle (as a "third kind" [triton genos]; Timaeus 48e4), a space, a material substratum, or an interval. In Plato's account, khôra is described as a formless interval, alike to a non-being, in between which the "Forms" were received from the intelligible realm (where they were originally held) and were "copied", shaping into the transitory forms of the sensible realm; it "gives space" and has maternal overtones (a womb, matrix):

Atlantis (Ancient Greek: Ἀτλαντὶς νῆσος, romanized: Atlantìs nêsos, lit. 'island of Atlas') is a fictional island mentioned in Plato's works Timaeus and Critias as part of an allegory on the hubris of nations. Purposely creating a literary contrast with the Achaemenid Empire, the great land-based power that ruled the east (what the Greeks called Asia), Plato describes Atlantis as a naval empire from the west that had conquered most of Europe and Libya, but then loses divine favor after an ill-fated campaign against a fictionalized Athens and subsequently submerges into the Atlantic Ocean. By portraying the victorious Athens in the image of his ideal state from the Republic, Plato intended the Atlantis story to bear witness to the superiority of his concept of a state.

Despite its minor importance in Plato's work, the Atlantis story has had a considerable impact on literature. The allegorical aspect of Atlantis was taken up in utopian works of several Renaissance writers, such as Francis Bacon's New Atlantis and Thomas More's Utopia. On the other hand, nineteenth-century amateur scholars misinterpreted Plato's narrative as historical tradition, most famously Ignatius L. Donnelly in his Atlantis: The Antediluvian World. Plato's vague indications of the time of the events (more than 9,000 years before his time) and the alleged location of Atlantis ("beyond the Pillars of Hercules") gave rise to much pseudoscientific speculation. As a consequence, Atlantis has become a byword for any and all supposed advanced prehistoric lost civilizations and continues to inspire contemporary fiction, from comic books to films.

In geometry, a Platonic solid is a convex, regular polyhedron in three-dimensional Euclidean space. Being a regular polyhedron means that the faces are congruent (identical in shape and size) regular polygons (all angles congruent and all edges congruent), and the same number of faces meet at each vertex. There are only five such polyhedra: a tetrahedron (four faces), a cube (six faces), an octahedron (eight faces), a dodecahedron (twelve faces), and an icosahedron (twenty faces).

Geometers have studied the Platonic solids for thousands of years. They are named for the ancient Greek philosopher Plato, who hypothesized in one of his dialogues, the Timaeus, that the classical elements were made of these regular solids.

Timaeus of Locri (pronunciation in modern English /taɪˈmiːəs/; Ancient Greek: Τίμαιος ὁ Λοκρός, romanized: Tímaios ho Lokrós; Latin: Timaeus Locrus) is a character in two of Plato's dialogues, Timaeus and Critias. In both, he appears as a philosopher of the Pythagorean school. If there ever existed a historical Timaeus of Locri, he would have lived in the fifth century BC, but his historicity is dubious since he only appears as a literary figure in Plato's works; all other ancient sources are either based on Plato or are fictional accounts.

Critias (/ˈkrɪtiəs/; Greek: Κριτίας), one of Plato's late dialogues, recounts the story of the mighty island kingdom Atlantis and its attempt to conquer Athens, which failed due to the ordered society of the Athenians. Critias is the second of a projected trilogy of dialogues, preceded by Timaeus and followed by Hermocrates. The latter was possibly never written and the ending to Critias has been lost. Because of their resemblance (e.g., in terms of persons appearing), modern classicists occasionally combine both Timaeus and Critias as Timaeus-Critias.

Hermocrates (/hɜːrˈmɒkrəˌtiːz/; Ancient Greek: Ἑρμοκράτης, romanized: Hermokrátēs, c. 5th century – 407 BC) was an ancient Syracusan general from Greek Sicily during the Athenians' Sicilian Expedition in the midst of the Peloponnesian War. He is also remembered as a character in the Timaeus and Critias dialogues of Plato.

The concept of the anima mundi (Latin), world soul (Ancient Greek: ψυχὴ κόσμου, psychḕ kósmou), or soul of the world (ψυχὴ τοῦ κόσμου, psychḕ toû kósmou) posits an intrinsic connection between all living beings, suggesting that the world is animated by a soul much like the human body. Rooted in ancient Greek and Roman philosophy, the idea holds that the world soul infuses the cosmos with life and intelligence. This notion has been influential across various systems of thought, including Stoicism, Gnosticism, Neoplatonism, and Hermeticism, shaping metaphysical and cosmological frameworks throughout history.

In ancient philosophy, Plato's dialogue Timaeus introduces the universe as a living creature endowed with a soul and reason, constructed by the demiurge according to a rational pattern expressed through mathematical principles. Plato describes the world soul as a mixture of sameness and difference, forming a unified, harmonious entity that permeates the cosmos. This soul animates the universe, ensuring its rational structure and function according to a divine plan, with the motions of the seven classical planets reflecting the deep connection between mathematics and reality in Platonic thought.

The microcosm–macrocosm analogy (or, equivalently, macrocosm–microcosm analogy) refers to a historical view that posited a structural similarity between the human being (the microcosm, i.e., the small order or the small universe) and the cosmos as a whole (the macrocosm, i.e., the great order or the great universe). Given this fundamental analogy, truths about the nature of the cosmos as a whole may be inferred from truths about human nature, and vice versa.

One important corollary of this view is that the cosmos as a whole may be considered to be alive, and thus to have a mind or soul (the world soul), a position advanced by Plato in his Timaeus. Moreover, this cosmic mind or soul was often thought to be divine, most notably by the Stoics and those who were influenced by them, such as the authors of the Hermetica. Hence, it was sometimes inferred that the human mind or soul was divine in nature as well.
