The herald’s wand is mentioned in association to Hekate in the “Charm of Hekate Ereschigal Against Fear of Punishment” PGM LXX. 4-25 in reference 51.
“If He [i.e., a punishment daimon] comes forth, say to Him: ‘I am Ereschigal, the one holding her Thumbs, and not even one evil can befall her!’ If, however, he comes close to you, take hold of your right heel and recite the following: ‘Ereschigal, Virgin, Bitch, Serpent, Wreath, Key, Herald’s Wand, Golden Sandal of the Lady of Tartaros!’ And you will avert him. ‘ASKEI KATASKEI ERO’N OREO’N IO’R MEGA SAMNYE’R BAUI (3 times) PHOBANTIA SEMNE, I have been initiated, and I went down into the underground chamber of the Dactyls, and I saw the other things down below, Virgin, Bitch, and all the rest!’ Say It at the crossroad, and turn around and flee, because it is at those places that she appears. Saying it late at night, about what you wish, it will reveal it in your sleep; and if you are led away to death, say it while scattering seeds of sesame, and it will save you.”
