Solon is said to have lived around circa 600 B.C.
In Plato's Dialogues relating to his talks with Solon
Timaios (20d to 27a) and Kritias (108c to 109a and 113a et seq.)
Plato refers to Atlantis
as a "metallurgical" culture
(clearly a reference to volcanic metals)
existing 9000 years prior to Solon.

Ancient scholars seem to have erred in the end zero, and the correct
number is surely 900, giving us somewhere around 1600 BC,
which in fact is close to the estimated date
of the explosion of the volcano Santorini on Thera.

Pellegrino gives a date of 1628 BC as based on
Carbon 14 radiocarbon data, dendrochronology
(bristlecone pines of California's White Mountains),
successive generations of oak trees (from Irish peat bogs),
and ice cores from the Greenland ice sheet.

The same argument of "one zero too many" also applies to the
size of Atlantis, everything being made a power of 10 larger than
the actual size.

Plato also reports of the fact
that no ships could pass near the island because of the brimstone.
This would hardly be a large continent
but is a phenomenon reported for Thera at that time.

The other statement of Plato (through Solon) that Atlantis was
outside of the "Pillars of Heracles (Hercules)" - a main argument
against the Thera identification -can clearly be shown NOT to apply
to the Straits of Gibraltar, as sometimes thought.

Indeed, a location near Thera and Crete is fairly certain.
After all, it was Eurystheus who imposed 12 Labors on
Hercules (Herakles, Heracles) among which are the following labors
in the general locale of Crete and Thera:

Labor Number 7
Capturing the wild bull that terrorized the
island of Crete (i.e. the Minotaurus of Menes the Minoan);

Labor Number 10
Seizing the cattle of the three-bodied giant Geryon,
who ruled the island Erythia (meaning Red) in the
far west, and,

Labor Number 11
Bringing back the golden apples kept
at the world's END by the Hesperides
(daughters of evening, i.e. West),
which were guarded by a DRAGON - what other
natural phenomena, other than a volcano, fits a fire-spewing dragon?
- and, indeed, a dragon may have been the ancient's explanation
for what a volcano was.
