The luthier of Delft is a work that analyzes the music (but also art and science) of the seventeenth century, with particular focus on Dutch culture. The book revolves around three central characters, the painter Jan Vermeer, the philosopher Baruch Spinoza and musician Jan Sweelinck Pietrszoon. From them, the reader will find the construction of musical instruments, their woods and varnishes, as well as the role of women in art and music; the lives of the painters and the symbolic world of his works and scientific studies for the optical and dissemination of the telescope. A book full of resonances and harmonies, wisdom and subtlety.
