. 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.
Historicity
In Plato's works, Timaeus appears as a wealthy aristocrat from the

), who had served in high offices in his native town before coming to Athens, where the dialogue of ''Timaeus'' is set. Plato does not explicitly label Timaeus a Pythagorean, but leaves enough hints for the reader to infer this. He appears competent in all areas of ancient philosophy, especially
natural philosophy and
astronomy.
In antiquity, Timaeus's historical existence was beyond dispute.
Cicero reports that Plato traveled to Italy to study with Timaeus and other Pythagoreans. The report of this meeting led

. The main reason for assigning the status of a literary fiction to Timaeus is the lack of any information that does not stem ultimately from Plato's dialogues.
As a counterargument, it has been pointed out that most characters appearing in Plato's dialogues are in fact historical persons.

entitled ''On the Nature of the World and the Soul'' ( grc, Περὶ φύσιος κόσμω καὶ ψυχᾶς, Peri phýsios kósmō kai psychās), also called the ''Timaeus Locrus'' after its purported author, starts out by declaring that: "Timaeus of Locri said the following", and proceeds to summarize the theories that Timaeus defends in Plato's ''Timaeus''. The book has been preserved fully, in more than fifty manuscripts. It is mostly consistent with Plato;
it notably omits the
Theory of Forms.
''On the World and the Soul'' was first mentioned in sources of the second century AD (
Nicomachus and the commentary on ''Timaeus'' by
Calvisius Taurus) and its authenticity was not doubted in antiquity.
The work was even believed to have been a main source for Plato's dialogue; a rumor dating back to the third century BC held that Plato's ''Timaeus'' was
plagiarized from a Pythagorean book, and this became connected to the ''Timaeus Locrus''.
Modern
philology has shown that ''On the World and the Soul'' is a
pseudepigraphon from somewhere between the early first century BC to the early first century AD, and is based on Plato's ''Timaeus'', rather than the other way around.
The Pseudo-Timaeus employs a simplified mode of reasoning and presentation, presenting conclusions rather than arguments and omitting any dialogue, meaning that it was perhaps intended as a summary of the notoriously difficult original for use in a classroom setting. While it may have originated in part as a set of lecture notes to the Platonic original, it tends to omit difficult sections of the ''Timaeus'' rather than provide explanations. Some of Pseudo-Timaeus's theses are very hard to understand without knowledge of Plato's work.
''On the World and the Soul'' shows traces of
middle Platonist ideas and terminology; in particular, it resembles works by
Eudorus of Alexandria and
Philo, making it plausible that the author lived in
Alexandria and was familiar with Eudorus's philosophy. He modernized the natural philosophy of Plato's ''Timaeus'' by incorporating insights from
Hellenistic

astronomy and medicine.
The book also appears to incorporate material from one or more now-lost commentaries on ''Timaeus''. R. Harder hypothesized that the composition of ''On the World and the Soul'' was a two-step process, whereby Pseudo-Timaeus, the author of the preserved version of the book, would have edited an earlier, Hellenistic variant of ''Timaeus''.
[Harder's hypothesis is accepted by ] Th. Tobin, by contrast, believes the work to have been composed at once, then translated into Doric.

Iamblichus, Syrianus, Proclus, and
Simplicius. The work of Pseudo-Timaeus supported the widely held Neoplatonist conviction that Pythagoreanism and Platonism constituted a singular theory, reflecting the pseudonymous author's intention of placing Plato in the Pythagorean tradition.

scholia on Plato's ''Timaeus'' ascribe to Timaeus of Locri a work entitled ''Mathēmatiká'', of which nothing else is known. This is possibly a false attribution, confusing Timaeus with an astronomer bearing the same name. He is also reported to have authored a biography of
Pythagoras, but this may be a confusion with the historian
Timaeus of Tauromenium, who devoted part of his history to Pythagoras's life and work.
