Who dated Tarquinia Molza?

Tarquinia Molza (1 November 1542 – 8 August 1617) was an Italian singer, poet, conductor, composer, and natural philosopher. She was considered a great virtuosa. She was involved with the famous Concerto delle donne, although whether she sang with them or coached them is not clear. She also played the viola bastarda, viola da mano, clavier, and lute. Trained in both distinctly male and female singing styles, her contributions helped combine them into the madrigal of the late Renaissance.

Giaches de Wert (also Jacques/Jaches de Wert, Giaches de Vuert; 1535 – 6 May 1596) was a Franco-Flemish composer of the late Renaissance, active in Italy. Intimately connected with the progressive musical center of Ferrara, he was one of the leaders in developing the style of the late Renaissance madrigal. He was one of the most influential of late sixteenth-century madrigal composers, particularly on Claudio Monteverdi, and his later music was formative on the development of music of the early Baroque era.
