Try doing a google image search, and see if any of those images resonate for you. You could print an image and use it temporarily as you decide if this goddess is calling you. Once that decision is made, you will feel more comfortable obtaining a permanent representation. This worked well for me.

I agree with what Lady Raushanna de Danu has said. If you are not sure that she will be a goddess you dedicate yourself to, then you can first find a digital representation and print it out or have it pulled up on your device when you are working with her at your ritual or meditation. Artemis is an incredible goddess to work with, she is one of my primary goddesses that I work with.

I have printed images, I bought some quality paper that was a little heaver than standard but not quite photo quality if I didn't have the funds, and then put them in dollar store frames. Sometimes I would decorate the frames with found items like rocks and moss, or beads and buttons, or sea shells depending on the deity and what they like. I have also used semi precious stones to represent the deities, like I did in the last Lughnasadh ritual, when I used a carnelian shaped heart for Lugh and tree agate sphere for Danu. In the past I have used a selenite sphere for Artemis and a quartz pillar for Apollo before too. Though you could use any of her correspondences to represent her, even a child's deer toy if you wanted to. If it had meaning to you and you thought she would enjoy the meaning behind it. My point is don't limit yourself to traditional representation. You can expand to many different things!

Lunas Dragonfyr It will suffice to use an image of Artemis on mobile device or printed as others suggested. I often use oracle cards that have a representation of the deity I am working with. Will this image
work for you?
