Drawing of the Threschelonia



Study of winged frogs
The professor had many connections. We traveled in all imaginable and unimaginable ways, he commented to us mysteriously. He also did not want to give us precise information about the nature of the research. I was never a scientist, but I believe that the professor wanted to provoke a revolution in the state of knowledge of that time. (...) I made a vow to keep silent about some of the things I saw in those years. And please don't ask me why!
