A pantheon (from Greek πάνθεον pantheon, literally "(a temple) of all gods", "of or common to all gods" from πᾶν pan- "all" and θεός theos "god") is the particular set of all gods of any polytheistic religion, mythology, or tradition:
A pantheon is an overview of a given culture's gods and goddesses and reflects not only the society's values but also its sense of itself.
Pantheon can also refer to a temple or sacred building explicitly dedicated to "all deities", avoiding the difficulty of giving an exhaustive list. The most known such structure is the Pantheon of Rome, first built between the years 27 BCE and 14 CE. The building standing today was constructed on the same site around 126 CE. It was dedicated to "all gods" as a gesture embracing the religious syncretism in the increasingly multicultural Roman Empire, with subjects worshipping gods from many cultures and traditions. The building was later renovated for use as a Christian church in 609 under Pope Boniface IV.
