Snakes
Hekate is described as being crowned with wild snakes, having snakes around her wrists and waist, and sometimes appearing with snakes in her hands.
Swords or Daggers
Hecate is shown holding a short sword or dagger in many ancient images.

The moon
Hekate was closely associated with the Moon during the early Roman period, perhaps due to a merger with the Moon Goddess, Sister and counterpart of Helios the Sun.
I was actually wondering if you speak Greek with Hecate and the other gods & goddesses? I noticed you spelled it Ekati (which is how it sounds when you say her name in Greek.) 
I speak three languages so I’m like… which one should I go for? I speak English and sometimes mix Swedish in, where I see fit. There is this Swedish saying my man usually says out loud: “Gud ge mig styrka” which translates “God give me strenght” and sometimes it sounds more fun in Swedish.
