Random Quote

10 February 1588: “All incompetent singers in the cathedral are warned that they must immediately begin to improve themselves or be fined. Regularly scheduled practice hours shall be announced, and all incompetents must attend. No one shall henceforth sing anything by way of a solo except those whose names the dean communicates to Guerrero.”

— From the “Life of Father Francisco Guerrero”
