When to summon Vapula?

Vapula is a Duke and he comes from the area of Netzach or from the shell of Netzach, that is, from Harab Serapel. All the Dukes of Goetia comes from these areas, and these areas are ruled by planet Venus.
I use the correspondences of Netzach even for Harab Serapel:
Ruling planet: Venus
Day: Friday
Astrological hour: Venus
Paper seal colour: green
Metal seal: copper
Number: 7 (7 spell items like 7 green candles)
Herb: cinnamon (my own choice)
Scent: sandalwood
The best day to summon Vapula is a Friday of course. You can fine tune your magick by doing it during the astrological hour of Venus.
