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. ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/is-it-the-art-mystery-podcast-7505217/episodes/is-it-a-van-dyck-with-professor-nils-b-ttner/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/is-it-the-art-mystery-podcast-7505217/is-it-a-van-dyck-with-professor-nils-b-ttner.md` — Read the agent-friendly Markdown representation of this episode resource.
