Bibliotheca Entendue is a 64-page hardcover book measuring 240 x 290 mm, published in 2025 with ISBN 9789083612713. The book explores the theme of observing animals, inspired by the author's childhood memories of sketching elephants with their father at the Blijdorp Zoo in Rotterdam. It reflects on how these observations evolved, particularly during a final visit with their father who was suffering from Alzheimer's disease, where the elephant drawings became abstract yet conveyed a direct and genuine essence, reminiscent of children's art.
