very summit of fifteenth-century musical art and artifice.
The later   composers   in  the line,   Italians    who were    both    temporally  and geographically  remote  from
the origins of  the tradition,  probably    thought of  it  as  a   “purely musical”    tradition,  and a   rather  academic
one at  that,   involving   nothing more    than    a   test-piece  to  establish   professional    credentials.    The
circumstances   attending   the earliest    L’Homme Armé    Masses—circumstances    probably    well    known   to  the
composers   of  the “Tinctoris” generations—suggest that    there   was originally  a   lot more    to  it. These
circumstances   point   to  the court   of  Burgundy,   and in  particular  to  a   knightly    order   founded there,  as  the
site    and source  of  this    most    famous  of  all emulatory   traditions  in  music.
In  1453,   Constantinople  (now    Istanbul    in  Turkey),    the largest and most    splendid    city    in  all of  Europe,
the capital of  the latter-day  Roman   (Byzantine) Empire  and the seat    of  Greek   Christendom,    fell    after   a
two-month   siege   before  the gigantic    cannons of  the Ottoman Sultan, Muhammad    II  (“The   Conqueror”).
Muhammad    made    it  the capital of  his empire, which   it  remained    until   1918,   and it  has been    a   Turkish and
a   Muslim  city    ever    since   its conquest.   The European    response    to  this    stunning    event   was one of  horror  and
professed   resolve,    but little  action. (Indeed,    the armies  of  Constantine XI, the last    Byzantine   emperor,
were    defeated    largely because no  European    power   sent    aid.)   In  immediate—if    ultimately  futile—reaction
to  the calamity    of  Constantinople, Duke    Philip  the Good    of  Burgundy    vowed   to  go  on  a   Crusade against
the Turks.  On  17  February    1454    he  convened    at  Lille   in  northern    France  a   great   meeting of  his own
knightly    retinue,    known   as  the Order   of  the Golden  Fleece. At  this    meeting,    known   as  the Banquet of  the
Oath    of  the Pheasant,   the Knights of  the Order   were    sworn   to  the defense of  Constantinople. Descriptions
of  the proceedings by  court   chroniclers recount the lavish  musical performances    that    enlivened   the
banquet.    At  the climax, right   before  the oath    itself  was sworn,  a   giant   led in  an  elephant    on  whose   back
was a   miniature   castle, from    which   a   woman   dressed in  mourning    sang    a   lament  for the fallen  city—
perhaps one of  four    such    Constantinopolitan  laments that    Guillaume   Du  Fay is  known   to  have    written,    of
which   one survives.
This    gives   us  some    idea    of  the manner  in  which   ceremonial  music   was “consumed”  by  the court   of
Burgundy,   and the sorts   of  occasions   that    the great   musicians   of  the day were    expected    to  dignify.    A   great
deal    of  sacred  music   has been    circumstantially    associated  with    the Order   of  the Golden  Fleece, including
many    of  the early   L’Homme Armé    Masses, which   date    from    the period  when    the Order   had become  at
least   nominally   a   crusading   order   and when    Philip  the Good’s  famously    belligerent son and eventual
successor   Charles the Bold    had become  active  in  it. Charles is  already known   to  us  as  the patron  of
Antoine Busnoys,    who had entered his service shortly before  Charles’s   accession   to  the ducal   throne  in
1467.

Versailles, France).
The song    L’Homme Armé    was a   special favorite    of  Charles,    who identified  himself with    the titular
“Man    at  Arms”   (probably   Christ  himself,    if  the connection  with    Crusades    was there   from    the beginning).^4
The song    may even    have    been    written for Charles.    In  any case,   we  know    the song    as  a   song,   text    and all,
thanks  to  the chance  survival    of  a   manuscript  containing  a   cycle   of  six anonymous   L’Homme Armé    Masses
