Budapest hosted the first complex science-art symmetry event in 1989. Following an odyssey through Japan to the United States, and through Israel to Russia, the event series returned to its birthplace in the early years of our decade. Symmetrology has shed its outdated (and sorrowfully discredited) first coat, lost its milk-teeth, and has revived at its roots in 2003. Symmetrology has grown in full age. It has passed through matriculation, although has not yet got its first degree.

Symmetrology has met the conditions of becoming a discipline of its own right. It has undergone a process of institutionalisation, it has formed its infrastructure. The pillars of this process are the following:

• symmetrology has its publication forum,
  - the journal Symmetry: Culture and Science in printed form, and
  - the website http://symmetry.hu in electronic form;
• regular meeting forum to bring together scientists of different disciplines and artists of  different forms of art, namely the Symmetry Festivals with their conferences, exhibitions and performances;
• symmetrologists have found their organisational framework under the umbrella of the International Symmetry Association;
• symmetrology has its specialised institute, the Symmetrion;
• it elaborated its curricula and entered in university education, assisting to shape the interdisciplinary thinking of the students;
• curricula have been published in textbooks in an increasing number;
• the bulk of symmetry related publications shifted from articles in scattered journals first to books of collected thematic essays, then recently to monographs, which can be charactarised with multidisciplinarity at an increasing extent.

Symmetry considerations broke through the shells of such disciplines that could have hardly believed before, appeared in new forms of arts. Over its more or less unified conceptual framework, there have been developed methods, approaches, general principles of symmetrology of its own.

The structure of scholarly knowledge (often called science) is under change. Look at this process from inside. Be at the appropriate place at good time. Join us, and let’s be together proud active agents of this progress.
