I remember certain engravings by Dürer and his obsessive attention to detail but I assure you it is not a mania but a necessity of the spirit. One can not seek perfection, after all what is it?, but why let me imagine things that are just as easy for me to do as not to do and while I do them my mind can think about the subsequent development. Specifically in this line I must confess that in addition to Dürer, Leonardo inspired me with his flying machines. Of course I was also inspired by certain structures of Hieronymus Bosch but this is obvious.
