Today’s featured picture is called Portrait of a Man. It certainly looks like a Velazquez. But you know what question I’m going to ask. Is it? To answer this question, I've invited two guests. First, Batu Arda Düzgün, originally from Turkey, is a researcher at Art Recognition, a company that uses artificial intelligence to help authenticate artworks. With a background that spans both computer science and art history, Arda is at the forefront of applying cutting-edge machine learning to some of the oldest and most mysterious paintings in the world. Joining him is British art historian Matthew Wilson, an expert on visual symbolism and the author of several widely-read books, including Symbols in Art, The Hidden Language of Symbols, and Art Unpacked, all published by Thames & Hudson. Matthew’s work uncovers the layers of meaning behind what we see, offering insight into the codes, allegories, and visual metaphors that artists have used across centuries. Arda’s work likewise uncovers layers of meaning but in the form of complex image analysis and the use of AI. What do they have to say about the artwork featured in today’s episode? Listen to find out.

**Featured in The Guardian** Caravaggio lived a violent fist of a life, but man could he paint. He is one of a handful of true revolutionaries, creating a style that was unlike anything that had come before, and was hugely influential. But he only made some 60 paintings, depending on which scholar you ask, so each is incredibly valuable. And not one has come up for auction in the last century or so. Today’s episode reveals some big surprises regarding three known versions of a painting called The Lute Player. But are all three by Caravaggio? Let’s find out in this special episode where I’m joined by British gallerist Clovis Whitfield and Art Recognition co-founder, Carina Popovici.

Most episodes of this podcast will feature a special guest art expert who chooses a painting that they’d like to have analyzed—a painting with uncertain or debated authorship. We are joined by, an AI specialist who reveals the test results and we discuss them together. But here and there we’ll include an interview that is relevant to the topic of art authentication, art historical mysteries, and technologies like AI, but which steps outside of the usual format. This is one such episode. In it, I’ll be interviewing one of the founders of Art Recognition, the firm that sponsors this podcast and runs the AI image analysis tests—Carina Popovici.

This episode of Is It? dives deeply into one of art history's enduring mysteries: The Polish Rider. A star attraction at the Frick in New York, it has long confused scholars. Is it entirely by Rembrandt? Mostly? Is it derivative or even a forgery? The brilliant art historian and critic Blake Gopnik is my guest to dive into this fascinating topic and much more, including Blake's book, "The Maverick's Museum: Albert Barnes and His American Dream."

Is it a Van Dyck? That’s the question we seek to answer in this episode. The painting in question is one of several versions of a Portrait of Don Diego Messia Felipe de Guzman, some of which are by Anthony van Dyck. But is this one? To answer this question, my guests for this episode include Prof. Dr. Nils Büttner, a distinguished art historian specializing in the visual culture of Germany and the Netherlands from the 15th to the 17th centuries; and Alita de Feudis, an art historian affiliated with Art Recognition, a Swiss technology company specializing in AI-driven art authentication.
