People ask frequently what to put on an altar or shrine for different gods. All anyone can ever give is suggestions, not guidelines, unless you’re part of a specific tradition or religion that mandates certain items. I’m compiling the general gist of what I keep telling people so that I can link this post instead of typing the same thing ^^;; I’m going to limit myself to Hellenic polytheism because there’s plenty of good posts on how to set up a shrine or altar floating around out there. Also, these are suggestions intended only as a starting point and should in no way be taken as authoritative instructions.
General gist of a shrine is a place for worship. Hellenic polytheism involves offerings; I am thus comfortable considering a space dedicated to the Theoi at which they receive offerings either a shrine or an altar or both, and I use the terms pretty interchangeably. On an altar, therefore, I would include as the basics: a symbol or icon either of the god or that reminds you of the god and a vessel of some kind for offerings. The vessel would vary based on what you plan to offer: incense needs an incense holder, libations need a dish, candles need candleholders and a fireproof environment, flowers might need a vase, etc.
I would then add anything that I want to dedicate to the god or anything that reminds me of the god and will thus aid in my worship. This might include devotional jewelry, candles, incense, crystals or precious stones, an altar cloth, statuary or figurines, trinkets, anything. I would select these items based on established symbols of the god and on personal associations I have. For instance, there’s a ballerina figurine on my shrine to Aphrodite – not because Aphrodite is the goddess of ballerinas, but because ballerinas indicate grace and beauty and strength to me, and those are very Aphrodite attributes.
