Though buried side by side in Westminster Abbey, Elizabeth I and Mary, Queen of Scots—cousins “of one blood”—never met in life. Their intertwined reigns ignited a ruthless clash of faith and power that culminated in Mary’s execution by Elizabeth’s command. Drawing exclusively from the queens’ own letters, poems, and speeches, composer Brett Dean and librettist Heather Betts trace their rivalry in Of One Blood.

Before the opera’s American premiere at Santa Fe Opera in 2027, join the creators for a conversation about the work and hear arias. All are invited to continue the conversation at a reception in the rotunda.
