  getElementById('_15th-century').caption = 'This instrument has been reconstructed from the picture by Hieronymus Bosch, entitled <cite>The Garden of Delights</cite>, painted sometime between 1500 and 1516. In the third panel of the painting, Bosch depicts Hell, and the sort of things that lead you to go to there! Bosch apparently took a very dim view of music, and thought musical instruments were the works of the Devil.';

It is believed to date from the reign of King Henri II (1547–1559), who died in the same year that Elizabeth I was crowned Queen of England.';
