    from

    fully incorporating

    these

    new works into his own

    analysis.

    When Goldstein carried out his dissertation studies in

    the 1980s at

    Omo,

    a Tiwanaku

    colony

    in the arid Mo-

    queguaValley

    of southern

    Peru,

    he

    applied

    a

    site-centered

    excavation

    framework similar to that

    carried

    out in the Ti-

    wanaku

    homeland. He

    initially interpreted

    Omo's

    temple

    platform,

    modeled

    on much

    larger originals

    in the

    capital,

    as evidence of a centralized

    altiplano authority

    consolidat-

    ing

    annexed

    territory hrough

    state ceremonies. One of the

    strengths

    of Andean

    Diaspora,

    however,

    is Goldstein's

    can-

    dor

    about

    the intellectual

    process;

    he describes how

    his

    thinking

    has evolved

    along

    with

    his

    dataset,

    which now

    in-

    cludes

    a

    full-coverage

    settlement

    survey

    over

    most of the

    Moquegua Valley.

    Afterhis first globalise nalysisat Omo, Goldstein be-

    gan

    to look

    more

    closely

    at individual

    and

    group

    identities,

    inspired

    by

    informal

    observations

    of

    present-day

    altiplano

    migrants

    in

    Moquegua

    and

    by

    the famous Andean

    verti-

    cal

    archipelago

    model

    proposed

    by

    John

    Murra

    (1985).

    The

    vertical

    archipelago

    s a mode of socioeconomic

    orga-

    nization-described

    in other mountainous

    areas

    but

    par-

    ticularly

    influential

    in

    Andean

    studies- in which

    a

    single

    community

    (variously

    defined)

    maintains

    a

    demographic

    presence

    in several resource

    zones,

    often

    at

    dramatically

    different

    elevations.

    Since

    the vertical

    archipelago

    model

    is

    sometimes

    criticized

    for

    excessive

    vagueness,

    Goldstein

    tightens

    the

    definition

    by adding

    two

    key

    conceptual

    in-

    gredients:

    the idea of diaspora o capture a longing for

    the

    homeland

    and

    a lack

    of

    assimilation

    into host

    commu-

    nities,

    and

    the

    ayllu,

    a much-debated

    Andean

    socioeco-

    nomic

    group

    based

    on

    real and

    mythical

    kin

    connections.

    According

    to

    Goldstein,

    Andean

    archipelagos

    are

    ayllus

    n

    diaspora

    p.

    42].

    Members

    of these

    archipelagos

    continu-

    ally

    redefine

    their

    identities

    (thus

    ethnicity

    n

    motion )

    in

    opposition

    to the

    other

    groups

    they

    encounter

    away

    from

    the homeland.

    Goldstein

    proposes

    four

    archaeological

    correlates

    for

    Tiwanaku

    ayllus

    in

    diaspora.

    First,

    he

    says,

    there should

    be

    large,

    permanent

    settlements

    outside

    the

    original

    core area.

    Second,

    the

    material

    culture

    of

    diaspora

    communities

    should

    closely

    resemble that of the homeland, indicating

    maintenance

    of

    everyday

    expressions

    of

    identity.

    Third,

    Goldstein

    says

    there

    should be

    evidence

    of structural

    re-

    production

    of

    internal

    social divisions

    similar

    to

    those

    of

    homeland

    populations.

    Fourth,

    there

    should

    be

    evidence

    of

    multiethnicity, groups

    of

    people

    with

    different

    material

    cultures

    and

    apparently

    different

    traditions

    living

    side

    by

    side without

    assimilation.

    Of

    course,

    only

    the

    first and

    sec-

    ond

    of these

    correlates

    are

    truly

    material

    correlates-

    in the

    sense

    that

    they

    refer

    directly

    to

    physical

    evidence

    and

    not

    to an

    inferred

    explanation

    for its

    patterning-

    and

    only

    the

    first

    is

    uncontroversial.

    Nevertheless,

    Goldstein makes a

    persuasiveargument that the archaeologicalrecord of the

    Tiwanaku

    colonies,

    and of the

    Moquegua

    Valley

    in

    partic-

    ular,

    contains

    evidence that fits

    within these

    categories

    and

    supports

    his

    explanation.

    He

    presents

    survey

    and excava-

    tion

    data from

    four

    major

    contexts:

    agrarian

    settlement

    patterns,

    household

    archaeology,

    burials,

    and

    public

    ritual

    architecture.Conclusions relevant to the

    correlates

    above

    are

    briefly

    summarized below.

    The settlement

    patterns

    of Tiwanaku

    colonists,

    who ar-

    rived in

    Moquegua

    in the

    mid-lst millennium

    A.D.,

    are

    markedly

    different from the

    local

    population,

    known as

    Huaracane.

    While

    dozens of small

    Huaracane settlements

    dotted the river'snarrow

    floodplain

    more or less uniform-

    ly, Tiwanaku established four large clusters of permanent

    settlements and

    irrigated

    fields

    (correlate one)

    at

    previous-

    ly unoccupied

    sites,

    a

    pattern

    that also occurredin the Lake

    Titicaca basin

    during

    Tiwanaku's initial

    rise to

    power.

    Moreover,

    differences

    among

    the settlement clusters-

    for

    example, overlap

    between distinct

    ceramic

    styles

    dubbed

    Omo

    and Chen Chen-

    seem

    to

    correspond

    to divisions in

    the Tiwanaku

    homeland

    populations, satisfying

    correlates

    three and

    possibly

    four. Additional evidence

    for correlate

    four is

    provided

    by

    an

    apparent

    lack

    of interaction

    with

    other

    occupants

    of the

    valley,

    the

    indigenous

    Huaracane

    and the

    contemporary

    colony

    established further

    up

    the

    valleyby

    the

    usually

    militaristicWaristate

    of the central

    Pe-

    ruvian highlands. The Wari chose a remarkablenatural

    fortress-

    the

    towering

    mesa of CerroBaiil-

    for their

    main

    settlement,

    but there

    is

    no evidence of warfare

    between

    the

    colonies,

    even

    though

    the

    heavy

    demands

    of Wari's

    upper-

    valley

    irrigation

    projects

    may

    have left Tiwanaku

    Examining

    the

    archaeology

    of Tiwanaku

    households

    in

    Moquegua,

    Goldstein

    posits

    a

    uniquely

    Tiwanaku

    habitus

    in

    ways

    of

    cultivation,

    capital,

    n

    the case of fine ceramics.

    The sheer

    number

    of burials-

    over

    20,000-
