Hi David
I agree with Con, the likelihood is overwhelming in my
opinion that this is not a Sulphur-crested but a
Yellow-crested or other closely related species from
Indonesia. The Yellow-crested occurs not only in Timor but
also Sulawesi and the lesser Sundas. There is every
possibility that one of these made its way to Venice, which
monopolised the spice trade in Europe from 1200 to 1500. This
from Wikipedia page on the Maluku Islands:
"By trading with Muslim states,
Venice came to monopolize the
spice trade in Europe between
1200 and 1500, through its dominance over
Mediterranean seaways to ports
such as
Alexandria, after traditional
overland connections were disrupted by
Mongols and
Turks. The financial incentive
to discover an alternative to Venice's
monopoly control of this
lucrative business was perhaps the single most important
factor precipitating Europe's
Age of Exploration."
I don't think there is the remotest chance of definitively
determining the actual identity of the cockatoo in the
painting - the detail just isn't there.
