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.
You can't be serious. Have you never heard of a "pantheon" before?
Also, horribly ironic, since Christianity is actually a family of individual religions. Have you seriously never heard of Roman Catholicism, Methodism, Southern Baptist, Greek Othrodox, etc. ?
Also, various pagan gods often have a central group of worshipers usually referred to as "cults". Examples would be the Cult of Odin or Cult of Athena. Members of cults primarily worship their chosen deity most people in a given culture wouldn't be as selective and worship gods when appropriate, like asking Thor for a good harvest.
Granted, this doesn't exactly apply to Celtic Paganism, but I'd be surprised if a practice common to the Greeks/Romans, Norse, Egyptians, Hindus, Zoroastrians, etc. didn't also apply
