This is posted in the waiting room of an Irish hospital. Interesting glimpse into their culture.
The full text of the poster
This symbol has been developed by the Hospice Friendly Hospitals Programme to respectfully identify the End of Life.
This symbol is inspired by ancient Irish history; it is not associated with any one religion or denomination.
The white spiral represents the interconnected cycle of life, birth, life and death.
The white outer circle represents continuity, infinity and completion.
Purple has been chosen as the background colour as it is associated with nobility, solemnity and spirituality.
In this hospital the symbol may be displayed on a ward to add respect and solemnity during end of life or following the death of one of our patients.
Many if not most religions historically didn't have a word for their particular belief system; the scholarly name for Germanic paganism is "Germanic paganism" because pre-Christian Germans didn't have a name for their shared beliefs. Sometimes you may see neologisms or names for neopagan movements applied to the now-dead religion — I've seen Germanic neopaganism (aka "Heathenry")'s less commonly-used "Asatru" used for the original religion in a game. Same with others like "Kemetism", which refers to the neopagan movement and not the ancient Egyptian religion.
Not a historical scholar but, to my understanding, for a lot of folks "what's your religion" would have been a nonsensical question because that's just how the world works and you wouldn't think of it as being a belief system separate from physically evident reality. Folks are free to correct me on that.
