The Mercury retrograde in December travels back from 29º to 13º Sagittarius. The retrograde lasts from December 3 to the 23rd. Mercury starts the retrograde conjunct Saturn, which right away tells us we are going to be retarded in our speech. Mercury Retrograde also falls on the very same day as a Full Moon which adds a fight between knight-in-shining-armour Aldebaran and his nemesis Antares. Frustrations are building, but Mercury Retrograde conjunct Saturn means people are gagged or punished for speaking out. The book-burning reaches a new peak during this Mercury retrograde. We don’t have the same optics as in 1933, but the effect is the same.
Ironically it is the same Nazi sub-text that is used to scare traditionalists into silence though, which is an interesting twist. But it’s Mercury retrograde and everything is upside down and opposite. Mercury and Saturn are on Acumen, which is a nebula found in the Scorpion’s tail, close to the stinger. Bernadette Bray says Mercury on Acumen (28º Sagittarius) brings; “Difficult or tedious mental endeavours; stressful financial dealings. Beliefs of ideas which place one at a disadvantage in the establishment. A time when persistence is needed to overcome a challenge”.  Those in the truth movement will just keep persisting!
Mercury Retrograde December Dates
November 15 ~ Mercury Pre-Shadow period starts at 13° Sagittarius.
December 3 ~ Mercury Retrograde at 29° Sagittarius (6.34 am UT.)
December 22 ~ Mercury Direct at 13° Sagittarius. (12.50 am UT.)
January 11 2018 ~ Post-Shadow ends at 29° Sagittarius.
Mercury Retrograde will be exact conjunct Saturn on Dec 5. On Dec 10 Mercury is trine Uranus which should bring some surprising, but awakening news. On Dec 11 Mercury Retrograde will align with Lesath, a star found right on the Scorpio’s stinger. This can be rapier wit or poison pen letters. A good example of someone with this placement natally was comedian Bill Hicks, he had Sun conjunct Mercury on Lesath. He is definitely someone who would be very vocal in the truth movement if he were alive today.
On Dec 12 Mercury will align with the shamanic star in the third eye of Ophuichus the serpent tamer. Mercury on Ras Alhague at 22º Sagittarius. Robson says “Unpopular attitude and criticism through religion, philosophy or science; difficulties in marriage and quarrels fostered by others, trouble through opposite sex, not very good for gain.”  Bernadette Brady says “Interested in spreading, investigating, or studying methods of healing. The medical researcher, the midwife or the herbalist. Health care in the news.” 
Now we are halfway through the whole retrograde journey with Sun cazimi Mercury at 21º Sagittarius. Here opens a window of wonderfulness where we can stand in the eye of the hurricane but miraculously come out in one piece. You can make use of the special Sun exact conjunct Mercury moment (Cazimi in traditional astrology). Send a romantic message that really hits the mark or pitch an artistic idea. Try as close to these times as you can. Dec 12: 3.48pm PDT. 3.48pm EDT, 8.48pm GMT, 9.48pm CEST. Dec 13 7.48am AEST. (Cazimi lasts about 3 hours either side of the hour.)
Dec 14 Mercury Retrograde aligns with Sabik in Ophuichus. This star is supposed “give success in evil deeds”. This can be read in two ways; ‘evil deeds’ can simply be working in witchy ways with alternative health and divination, OR it can be the elite parasites doing actual evils deeds and being successful (as in the case of Harvey Weisten and his ilk.) Robson says that Mercury on Sabik brings “Injury from open enemies, little help from friends, failure in business, fairly good for gain but legal losses, scandal through relatives of marriage partner.”
On Dec 14 Mercury Retrograde is also conjunct Venus on Sabik which could actually mean a relationship with a witch 😉 Quite a good day for playing with your tarot cards then (Or your witch…) Mercury turns direct on Dec 22 while it is square Neptune, so some ugly truth might come to light on that day.
Mercury Retrograde Through The Decans
Mercury In Sagittarius Decan 3 ~ December 3 to 13
Here Mercury is the info warrior! This decan is challenged by the authority of both Saturn and the Sun as it’s ruler, so thought processes at this time are taken very seriously. It is like the weight of the world is on our shoulders and there will much deep contemplation. Information that is out in the public domain is examined very carefully, but this can also cause fear. In the worst cases the public can become very paranoid and depressed about what they read, in all forms of media. Many will be branded conspiracy theorists, when they are really just obsessed with finding the truth. Mercury here is visionary, but often its realistic, no-frills view of the future is bleak. There are grave warnings about health problems in the future due to pollutants in the environment.
This dystopian future is hard to swallow, so those that bring this news to the public are demonized for being a doomsayer. Traditionally, nit-picking Mercury is not comfortable in broad-sweeping Sagittarius. However, it can do very well researching subjects that are metaphysical in nature. Mercury here will love to study ancient mysteries, comparative theology and astrology. If Mercury is not boxed in by dogma it can really thrive, even in its so-called position of detriment. One of Mercury’s great gifts in Sagittarius 2 is a dark sense of humour and acerbic wit. The protective cloak of comedy means one is able to bring taboo topics and an anti-establishment stance to a wider audience.
Mercury In Sagittarius Decan 2 ~ December 14 to 23
This decan does not add any power to Mercury’s expression (Being in its detriment in Sagittarius.) The star Sabik is problematic too as it is associated with dabbling in the occult. What Mercury has here in bags however is curiosity, but this inquisitive trait allows it to stray into very dark dungeons. With Mercury Sagittarius 2, the expression ‘curiosity killed the cat’ is never more relevant. The problem is the blurring of intuition with intellect at this time. Those touched by the Mercury Retrograde here will find that cannot help but state as fact something they have gleaned purely by psychic means. The will have a sense of knowing, but difficulty proving their findings scientifically. This placement seems to work best for singers and artists since they are allowed to communicate in a poetic style without raising too many eyebrows. In an artistic framework this esoteric Mercury is able to explore its wildest theories and fantasies. However, those working in the more technical and left-brain Mercurial professions will find this period tough as it is quite psychedelic in its thought processing. Melting clocks, melting clocks..
Mercury Retrograde December 2017 Summary
Traditionally Mercury in Sagittarius is completely contradictory as Mercury has a microscopic action and studies close-up connections whereas Sagittarius stands back and observe the bigger picture. However Mercury in retrograde is operating in a more philosophical and introspective manner which resonates rather well with Sagittarian energy generally. Sagittarius 2 and 3 are also two of the most shamanic and otherworldly decans in the whole zodiac. Therefore this is a fantastic time for probing the deepest mysteries of our evolution.
Of course this is “Conspiracy Theory” heaven too, but the problem with that phrase is that it lumps in genuine revelations with really bonkers misinformation. However, all enlightened truth started off as a crazy, conspiracy theory at some point. David Ike raised the alarm about pedophiles in elite circles back in 1997 and was laughed at. Twenty years on it turns out he was totally right about British Prime Minister Edward Heath. So we can expect to some brave disclosures, but also that these whistle blowers will be branded as having mental problems, even going as far as them being sectioned! Generally the more crazy someone is painted in the media, the more you can be sure these folk have something important to say.
Mercury Retrograde General Meaning
When Mercury goes retrograde the traditional advice is “Don’t travel, Don’t sign contracts. Don’t marry. Don’t touch electrics!” But the whole Mercury retrograde cycle actually lasts eight weeks and happens three times, sometimes even four times in a year! That’s a long time to hide under the duvet and a real waste of a truly magical time. Mercury generally zips between two worlds, or rather, the two hemispheres of our brain. During the retrograde period it feels like Mercury has gone down into the underworld. In this realm, closer to spirit, we become more right-brain orientated. It is dark, so other senses are heightened. We will feel extra sensitive here, psychic even. Everything will seem hyper-real… you will notice things you had overlooked before.
This will prompt you to re-evaluate, renovate, re-form, and re-invent. It’s true you might have to redo things, because Mercury will hit the same degree three times, but this transit won’t let you go into autopilot. There are danger spots though. When Mercury is stationing retrograde we are at a wobbly stage where we are likely to slip-up, make mistakes, and misread another’s communications. Once we are over the threshold and into the Underworld, we can safely go about our business, knowing that we are in another realm. The same goes for when Mercury is stationing direct, just make sure you give your brain a few days to adjust back to solar thinking.
The house in your natal chart that Mercury retrogrades in, will be your Underworld zone. There you will question everything. It will make you jittery about signing contracts, because you will be constantly thinking, “Is this what I really want?”. Before the retrograde, is a good time to finish off those Solar left-brain projects and gather information to bring down with you into your retrograde cave. Then you can slow things down, let yourself be taken into other dimensions, try on different filters, experiment, shine a light on your demons, then recharge and reboot.
