Classical Greek Contributions
Geography is derived from two Greek
words, Ge Earth, and Graphe
Description.
Coined by Greek Geographer Eratosthenes who
viewed geography as descriptions of the earth.
But others (Egyptians, Sumerians, Phoenicians)
thought geographically before him, makinggeography possibly as old as humanity itself.
We are however mostly concerned with geography
as a systematic or organized body of knowledge
with defined concepts and procedures.

The Greeks had
A geographic curiosity often associated with
commercial and military interests and often
extending beyond their empire.
Seafaring skills and a need to improve them.
A robust mythology closely intertwined with a
polytheistic belief system that contained a godfor just about everything.

The Greeks had
A belief that celestial objects were epitomes
of gods, and therefore worthy of close
scrutiny. A need for a geometry and associated tools
to study the location and movement of
celestial objects.

The Greeks didnt have
At the beginning, any kind of information
source (other than word of mouth) that we
now take for granted.
Basic location and navigation skills
(including the compass).
An accurate system of measurement overlong distances.
Basic cartographic tools and techniques.

The Greeks didnt have
An understanding of the shape and size of
earth and of basic earth-sun relationships.
A understanding of basic earth scienceincluding erosion, deposition and
meteorology.
An appreciation of the adaptability of humanbeings to different climatic contexts.

Homer
Reportedly livedsometime between 1300 850 BC.
Considered by some to
be The father ofgeography because TheOdyssey, one of his epicpoems, provides the
earliest geographicaldescription of the fringeof the Greek world.
Also Wrote the Iliad
(1280-1180 BC) Mostlyhistorical.
The Odyssey

Thales of Miletus
(ca. 624 ca. 546 BC)
Advocated for a rational explanation of the
natural realm without reference to mythology.
Major contributor to field of geometry (e.g. circle
divided into two by diameter) and astronomy.
Credited with the development of the mathematical
tradition for his concern with measures of
location, distance and areas of things on the earths
surface (possibly for personal business reasons).
Speculated about the origins of the earth and
proposed a flat disc earth floating on water.

Teleological explanation vs. Mechanical explanation
Mechanical explanation
Phenomena and observations are theresults of purely natural (non-divine)
causes.
As related to geography, Earths
attributes are the products of natural
processes that may be explained byphysics, mathematics, biology and
other realms of human knowledge
whose contents rely on careful
observation, verification and testing.
Established explanations must be ableto withstand the test of time. Thus,
they may be replaced if subsequent
observation and analysis provide new
explanations that are superior to old
ones.
Teleological explanation
From the Greekteleos, meaningpurpose or end.
Things happen for a reason or purpose
that suggests Divine will.
As related to geography, Gods will is
revealed in nature as well as inscripture.
The world we inhabit was created by
God and exhibits an order, complexity
and purpose as designed by the
Creator. A careful inventorying of the worlds
attributes, as by geographical
exploration and analysis, may help us
understand Gods will even as it
proves Gods existence.

Anaximander
(ca. 610 ca. 546 BC)
Disciple of Thales
Claimed that nature is ruled by laws, just like
human society. Introduced the gnomon/Sundial (Babylonian) to
Greece.

From the gnomon it was possible to tell the
varying positions of the sun, being shortest at
noon. Varying noon shadow lengths from seasonto season also helped to establish whether it was
summer solstice (shortest) or winter solstice
(longest). The direction of shadows at sunrise and
sunset also helped to tell the time of the equinox
(sunrise and sunset shadows are colinear but
opposite.

Anaximander
Credited for being first
Greek to draw a world
map with distance and
direction to scale.
Helped establish the
cartographic tradition.
Tried to explain howsun rises in the east and
sets in the west but
rises again in the east. Interpretation of Anaximanders world map

Hecataeus
(ca. 550 ca. 475 BC)
No known artistic portrayal; name may refer to
more than one person.
Credited with the literary tradition.
Advocated taking stock of what is around us
and putting the accumulated knowledge of the
world together in a usable form.
First known Greek to collect and classify
information brought to Miletus not only from
the known Greek world, but also from
unknown lands beyond.

Hecataeus
(ca. 550 ca. 475 BC)
A principal founder of
idiographic/descriptive
tradition in geography.
UsedEurope,Asia, and
Libya as regional
divisions for his world
geography.

Herodotus
(484 ca. 425 BC)
Stressed the interrelationship between history and
geography all history must be treated geographically
and all geography must be treated historically
Travelled widely knew the shores of the
Mediterranean, travelled several days northward across
the Russian steppes, went eastwards over the PersianEmpire and south to Egypt.
Argued against the tradition of dividing Asians from
Libyans along the Nile river and insisted Egyptians are
not divided into Asians and Libyans along the Nile

Applied historical geographical methods to
correctly interpret the Nile delta as being
formed by silt deposits from Ethiopia. He was also fascinated by the summer flooding
of the Nile since other rivers flooded in winter.
Also credited with the idea of the wind blowingfrom colder to warmer places.
Sought explanations that reflected the notion of
an earth that was arranged symmetrically.

Herodotus
Mapped the known world with the Mediterranean
in the center and surrounded by Oceanus.

Plato
(428 348 BC)
Master at deductive reasoning
Deductive Method involves theorizing from the
general to particular events.
General/intuition/theory Particular Event
Proposed the idea that the world was deteriorating
from perfect state. Could well be the source of the
notion of environmental degradation.
Questioned the belief of a flat earth and confirmed
Pythagoras (6th century BC) hypothesis of a
spherical earth.

Plato
Appears to be the first
Greek philosopher to
announce and look forevidence to support the
concept of a round earth
centrally located in the
universe with celestial
bodies in circular
motion around it.

Aristotle
(384-322 BC)
Master of inductive reasoning
generalizing or formulating theories from
particular cases/events
Particular General/Theory
Suggested the physical environment is
improving towards a perfect state.
Sought an explanation of Platos idea of a
spherical earth.

Aristotle
(384-322 BC)
Postulated the concept of varying habitability
of the earth based on latitude. Accordingly:
The world consists of 5 climatic zones
The torrid zonecentered on the equator is
uninhabitable excessive heat.
The frigid zonecentered on the north and south
poles is uninhabitable too cold.
An intermediate/temperate zone called ekumene
located between the tropics and arctic and
Antarctic is habitable just right.
