    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.

  • 7/27/2019 History of Geographical Thought

    8/25

    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

    11/25

    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.

  • 7/27/2019 History of Geographical Thought

    14/25

    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.

    17/25

    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.

    Interpretation of the World Map of Hecateaus

    18/25

    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

    19/25

    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.

    21/25

    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.

    22/25

    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.

  • 7/27/2019 History of Geographical Thought

    23/25

    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.

  • 7/27/2019 History of Geographical Thought

    24/25

    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.
