We all know something about art to varying degrees, have heard something, noticed something by chance, and have been deeply convinced of something since childhood. When we come to a museum, the guide becomes an intermediary between us and art. It is he who can answer the question that interests us here and now. But sometimes, for one reason or another, he fails to do this, and we don’t always dare to ask about something. Alina Nikonova, an art critic and blogger, answers questions that you didn’t dare ask: why did Picasso paint such strange paintings and what is ingenious about them? - how to distinguish a good painting from a bad one? - how much does everything that is in museums cost? - is there something mystical in ancient Egyptian art? - why are some paintings attacked by madmen? - how to understand the paintings of Salvador Dali, if they are so unusual?
