Scriptural evidence for the role and compatibility of polytheism within Buddhism?

First of all, I would like to clarify that I am extremely new to Buddhism, Hinduism and Indian philosophy in general. I do not particularly consider myself an adherent of any of these traditions. I am doing research on Buddhism as part of a project I have to study the scriptures of every religion. With that out of the way, I would like to ask practicing Buddhists here if polytheism is compatible with Buddhist doctrine or *dharma*, and what the role of said polytheistic traditions are within Buddhism. I am a European polytheist who worships many members of the European pantheons, such as Germanic, Celtic, Roman and Greek deities. Is the worship of multiple Gods discouraged or encouraged within Buddhism? I know that the Buddhist scriptures mention Hindu deities like *Mahakala* and *Hayagriva*, but I have no idea where they are mentioned within the scriptural canon, and I have no idea what is said about them or in what context they are referred to. In summary: * Is **polytheism** *dharmic* or *adharmic*? * If it is *dharmic*, what is its role within Buddhism? * If it is *adharmic*, why is this the case? * What is the **scriptural basis** for your answer?
