This 1585 allegorical portrait by Marcus Gheeraerts the Elder is one of the first portraits of Queen Elizabeth of England that I saw.
The Luminarium calls this the Welbeck or Wanstead portrait. Marileecody.com calls this the Peace portrait. All attribute it to Marcus Gheeraerts the Elder. Marileecody's note is good: "In this portrait, the queen is the harbinger of peace. She holds an olive branch in her left hand and a sheathed sword lies at her feet. She is possibly wearing the same headdress, collar and girdle from the 'Ermine Portrait' (the next image - gogm). Also, both gowns are 'Polish style' with froggings.
From the date, we can assume the symbolism refers to the turbulent situation in the Netherlands.
I have read that this is the only definitively identified painting by Gheeraerts the Elder; it is certainly his only surviving oil portrait. I have named this portrait 'The Peace Portrait' for obvious reasons, but there is no widely-accepted title."
