Otto Pacht, one of the most significant art-historians of the 'Vienna School' turns his attention in this publication to the humanist circle of Early Renaissance painters in Venice, dominated by Jacopa Bellini, his sons Genrile and Giovanni, and also his son-in-law Andrea Mantegna. It was a period of newly awakened interest in the Antique, of studies made directly from nature, and of trial and error in the technique of perspective. Of the Bellini family, it has bee Giovanni who is generally regarded as the major figure of the dynasty.Pacht, however, devotes particular attention of Jacopo's work, interpreting it as the basis for his sons' later development. He analyses Jacopo's London and Paris Sketchbook drawings, demonstrating where lts Gothic elements can be seen to be overtaken by the need to give perceptive depth to the image, how subsequent painting took account of these changes. This is also the essence of Pacht's examination of Mantegna's work, where the construction of space and depth is the key to our understanding of Mantegna's creative process. Turning to the next generation of Bellini family, Pacht guides us to appreciate the refinement and perception of Gentile's portraits, and finally takes us step by step through the works of Giovanni, where fantasy combines with the play of colour and light in creating compositions, devotional images, and landscape setting of perfect harmony and beauty.
