Through the ages, the concept of symmetry has increased in richness and 
played an important role. In this lecture I will confine considerations 
to the role of symmetry in art, and, in particular, to two ornamental 
techniques. Reference will be made to historical examples of the 
systematic use of these techniques, from ancient times to the Islamic 
art up to the graphic work of M. C. Escher.


The art works of Professor Ghirardi -  "The Periodic Tarots"  - will be 
exhibited in the MB hall. They consist of 31tableaux that represent an 
hypothetical Tarot deck painted during the Seventies with acrylic 
colours which have been recently transferred, via a photographic 
technique, on supports of 31,5 x 50 cm.  His choice to resort to a 
tessellation procedure with identical tiles,  procedure used by Arab 
artists for ornamental purposes and representing  the fundamental 
artistic canon of the well-known engravings of the great Dutch graphic 
artist, m. C. Escher, has been carried out to stress the pervasivity of 
the images. Each image symbolizes a crucial moment of the psychological 
evolution of all individuals leading to  their maturity. This technique 
requires mastering, for artistic purposes, an extremely refined 
mathematical procedure based on group theory.

The exhibition will be displayed until the end of this week.

Everyone is welcome  to join in the Colloquim.
