Before the 1990s (possibly)
Behind the scenes
- Pius may have died sometime prior to the 1990s, as many portraits hung at Hogwarts Castle depict deceased individuals.
The name "Iris" means "rainbow" in Greek. Iris was the name of the Greek goddess of the rainbow. This name can also be given in reference to the English word (which derives from the same Greek source) for the name of the iris flower or the coloured part of the eye.
