In the TV series Constantine, the titular character uses the magic of different religions and regions. Many different types of magic are used as given here. Many ancient artifacts are used like sinew from Achilles' heel, the ring of Solomon, Icon of Pazuzu, etc. So what are the different countries whose magic is used by him?
The magic shown in Constantine mostly, although not entirely, derives from real-world beliefs about magic and religion, although some spells, such as the sleep spell, are not clearly tied to any tradition. Although most of it derives from European traditions, some comes from Africa or the Middle East, or occasionally Asia or South America.
Among the countries whose magic appears on the show, and in Constantine's follow-up appearances on other shows in the same cinematic universe after Constantine was folded into the Arrowverse, are:
- West Africa: Voodoo. Papa Midnite is a voodoo priest in the TV series. With a variety of spellings, Voudon refers to a set of religions and accompanying magical practices originally deriving from West African countries such as Benin and Nigeria. The form that Papa Midnite practices in the show may be more specifically from other regions, such as the state of Louisiana in the United States.
- Greece: Although I can't find a reference on the wiki, if the Heel of Achilles appears it would definitely be Greek. Also, as mentioned in other answers, pentagrams had a symbolic significance in ancient Greece. Their use on Constantine may owe more to a generic association with Paganism and Wicca in the US and Europe than their original ancient Greek uses, however. The appearance of magic associated with the five classical elements is also a nod to Greek philosophy and mysticism.
- Babylonia: The demon or god Pazuzu appears on the show as an enemy of Constantine. His name was used in protective amulets in ancient Mesopotamia generally. His enemy Lamashtu also appears later on. Pentagram magic was also practiced in ancient Babylonia, as was capnomancy; this latter was also practiced in Greece.
- Israel/Judah/Palestine/Canaan: The water of the Jordan harms evil beings, similar to holy water. The magic and cosmology of the series in general is also based heavily on Christianity, a religion originally founded in Israel: for instance, the presence of angels, demons, specific named demons such as Mammon or named angels such as Gabriel, Hell, and so forth. The Ring of Solomon is another example.
Europe: The hand of glory was believed in Europe to have powers capable of aiding a thief. I can't find a reference for the Grail being on the show, but it would also fit here. Obviously a Faustian bargain, named after Doctor Faustus, would also come from Europe. There are likely many other forms of magic in the series that come from Europe.
Wales: The coblynau, although the version in the show might draw inspiration from the Cornish knockers or the German kobolds.
Britain: Apparently, Constantine knows an old Brittonic spell to allow resurrection.
Egypt: The Eye of Horus, clearly.
Chile: The Brujeria practiced some ancient form of magic originating in what is now Chile.
Turkey: The demon Karabasan comes from Turkish lore.
Tibet: Constantine used the phurba, a Tibetan ceremonial dagger, for certain ritual purposes.
Well, just going off the list you gave, which doesn't include anything about Achilles (Greek legend), Solomon (Hebrew legend), or Pazuzu (Babylonian myth), you've got
Babylonia: capnomancy, exorcism
Christendom: Faust, grail, hand of glory
Egypt: Eye of Horus
- Neoplatonism: pentagrams
- Pythagoreanism: pentagrams
Israel: water of the Jordan
Wales: coblynau (but here credited to the Romani for no apparent reason)
It's all just standard fare Western magic + a bit of peasant folklore. Every country around the world has attempted to understand and control nature through mistaken ideas about supposed connections/correlations and imagined causes and effects. The most important for learned Western men have been Greece, Egypt, and Babylonia as interpreted through Jewish and Christian theology; you still get pieces of that in things like Freemasonry. You also have a parallel strain of peasant magic that's more focused on nature, herbs, and local traditions; witches (i.e. local wise women) have usually drawn from that. From your list, it seems like Constantine is squarely in those two camps and hasn't bothered as much with voodoo, santaria, and eastern traditions in India, China, &c.
