SEMINAR
Speaker : Mr. Arijit Mukherjee
Title
Decoding da Vinci Code…
Day, Date & Time: Thursday 3rd March, 2011 at 4:00 PM
Venue :
SSCU AUDITORIUM
Abstract:
The enigmatic smile may remain a mystery but there is a continuous effort
to crack it. A group of French scientists led by Philippe Walter say that
they have cracked a few secrets of the Mona Lisa. They studied seven of
the Louvre Museum’s Leonardo da Vinci paintings, including the Mona Lisa
to analyze the Leonardo’s use of a special technique that gave his works
their dreamy quality. It has been found that da Vinci painted up to 30
layers of paint on his works to meet his standards of subtlety. His use of
that technique is well-known, but scientific study on it has been limited
because it requires samples from the paintings. They used a noninvasive
technique called X-ray fluorescence spectroscopy to study the paint layers
and their chemical composition. The analysis of the various paintings
reveals that da Vinci was constantly trying out new methods. Apart
from
that, this talk will also concentrate on the master’s continuous research
on paint media which helped him to get the improved effect in his
paintings. In a nutshell, this talk will indicate the blending of science
and art into each other, from the time of Renaissance to the modern age.
