An artist painted a picture of Comet Halley centuries before the comet
was named.  More -- in a moment.

January 8  Comet Halley and Giotto de Bordone

Around the year 1304 the Italian artist Giotto de Bordone painted a
portrait of Comet Halley.  Giotto didn't know the comet he had seen was
Halley's.  The comet wouldn't begin to be called by that name until
another four centuries had passed.

Giotto saw Comet Halley around the time of its closest approach to the
sun in 1301.  Three years later Giotto painted a remarkable series of
frescoes depicting the life of Jesus in a chapel in Padua -- and
portrayed a comet over the stable in the nativity scene.

The use of a starlike object was not uncommon in such paintings in the
middle ages -- when the western church taught that any unusual
celestial sight was a sign of an earthly event.  But earlier pictures
of comets -- like all mediaeval art -- were stylized, unnatural-looking
representations.  For example, a comet would be shown as a
multi-pointed star with with extra long rays to one side.  Giotto
painted a more realistic image of the luminous coma that surrounds the
comet's head -- with a tail streaming away from the sun.  His
innovative style of realism had an extraordinary influence on western
art.

Another Giotto will provide new images of Comet Halley next year.  This
Giotto is a spacecraft that will pass near the comet and photograph it
as it returns once again to visit the sun.  The European Space Agency
named their Halley space mission Giotto in honor of the Italian painter
-- one of the greatest early examples of people who have contemplated
celestial objects -- and been inspired to record what they see.
