The book "Jacomo tentor f. Mycelium for Tintoretto Research" by Erasmus Weddigen offers a comprehensive analysis of the life and work of the Venetian painter Jacopo Robusti, better known as Tintoretto. This scholarly work illuminates the complexity of his oeuvre, which is shaped by a variety of influences, including his engagement with Titian and the legacy of Michelangelo. Weddigen compiles over 30 years of research findings that address various aspects of Tintoretto's art and biography. The contributions are designed as a "mycelium," representing a fertile ground for future studies. Particularly highlighted are the "Miracles of St. Mark" and their significance for the Scuola Grande di San Marco, as well as the associated commission relationships and hypothetical portraiture. This book is an essential work for anyone wishing to engage deeply with art history and the figure of Tintoretto.
