Haunted by a face, or the mystery of eternal self-portraits

According to certain views of art history the artist at the beginning of his career, until he lacks his own evolved style, can only paint or draw himself instead of drawing portraits on others. According to other views this remains so during the whole artistic career as the artist gets his own character involuntarily into the completed artwork. It is like transmitting our DNS in a logic way on a piece of paper by means of a pen or a brush in our hands. Would a genetic relationship come into existence between the artist and the artwork? All right, let's try to decode this! The idiosyncrasy of certain components (e.g. handling the brush, conducting lines, the resources of motives) assimilates the completed artworks too. As far as here it does not sound strange as each artist has his own style. But what is the artist as a biological being? It would be an obvious explanation that our drawings resemble what we see the most in life. We see ourselves the least and only from a mirror which has the disadvantage of providing an inverse image but always from one viewpoint. Therefore painting our own selves always originates from an ancient, instinctive and subconscious skill, or if you like, it is part of our supernatural talent. Sure enough that there is no scientific answer for the question of eternal self-portraits mystery, moreover there is such a vagueness that nobody can give an answer whether which academic area will support this theory by further facts. Will it be psychology, genetics or ethology? One thing is sure that till then art history will be emitting further evidence of the mystery. However I truly don't understand how experienced professionals could nowadays be in fever apropos of the disputatious Mona Lisa misery. Let me illustrate my short conception again with the art works of Téglás István. If you do not know him and would like to get to know who should the exhibited statues and paintings resemble than visit http://www.teglasistvan.blogspot.com and watch him in the movie titled "Pear wood Hero".
