Hildebrand Jacob was born probably in Bromley, Kent, and died in West Wratting, Cambridgeshire. The son of a baronet, cultured and widely travelled, he was a poet and dramatist. A number of his works were performed at Drury Lane; The Fatal Constancy (1723) was probably his best work, while many later works were badly received. Of the Sister Arts (1723) sets out his philosophical views on the arts and literature. Following Cicero, Jacob believes that all the arts are related in some way, but those most closely connected are poetry, painting and music, the ‘sister arts’ of the title. They have in common, he says, the animation of life and spirit. They achieve this animation through two principles: imi-tation, the reflection of life and spirit; and harmony, the summoning together of the parts so as to achieve animation. He compares how these principles apply to the various arts, and provides a number of basic rules and techniques based on them. Jacob's son, Sir Hildebrand Jacob, was a noted Hebrew scholar.
