It
was proposed for the reredos of a somewhat narrow
but high ceilinged church. It would have been executed
in secco fresco on plaster. This is a very old technique
which
allows the artist more time to finish details and complex
designs in contrast to true fresco which must be done
in wet plaster and with a continuing plastering day by
day on
the areas that the artist can complete in one day. If
you examine the Sistine ceiling you can see the lines of
each batch of plaster.
In
secco fresco there are no lines as the plaster is done
all at once before the painting begins. The ancient Egyptians
used a form of secco fresco, so it's a long-ago method.
Today,
I would use acrylic with a matt finish, which would be
a piece of cake compared to true fresco.
