It is possible to get some sort of chart for both Christianity and Islam by using the start dates for the Christian and Muslim Calendars respectively. (See Nick Campion's 'Book of World Horoscopes')
The Christian Calendar can be set up for 12am 1st Jan 0001 AD. (Click for larger image).
With Jupiter on the ASC opposite Mars in Aries on the DESC (‘open enemies’) square to the Sun, the expansive (Jupiter) and crusading (Mars) nature of Christianity seems to be clear. Islam has also spread widely, but it is not worldwide in the way that Christianity is.
The Muslim Calendar can be set up for July 16 622 AD at 6.45pm in Medina, Saudi Arabia: this is the traditional date of Mohammed’s arrival (at sunset) in Medina. These are both symbolic rather than literal charts, but so is the US Sibly chart! And astrology itself is symbolic.
Islam is much more identified with its place of origin, the Middle East, than is Christianity, and I think we can see this from its Sun in Cancer on the DESC conjunct Saturn: it is concerned to defend (Saturn) the homeland (Cancer) from its enemies (DESC). The Moon (Home) in the 7th House (enemies) seems to reinforce this point. With most of the chart in the 7th, opposition and enemies would seem to be central to Islam, it’s as though it wouldn’t know itself without them. Like an old friend of ours who also has Sun in Cancer and unaspected Mars in Virgo, George W Bush.
If you Progress the Christian Chart to 1095 AD, the date of the first Crusade to the Holy Land, you find Pluto stationary Retrograde. The Progressed Chart for 1271, the year of the final Crusade, has Pluto stationary Direct. So the Medieval Crusades involved a whole Progressed Pluto cycle for Christianity. If we fast forward to 11th Sept 2001, what do we find? Progressed Pluto stationary Direct! The start of a whole new cycle of aggression against Islam.
That this new cycle is not just a one-way process is confirmed by Progressing the Islamic Chart to 11th Sept 2001, and setting it for New York. What we find is progressed Pluto at 25.02 Aries, within 5 minutes of the MC at 24.57 Aries.
As I have written elsewhere, the War on Terror (using the 9/11 chart for its beginning) had a progressed New Moon in August 2007, heralding a major new phase in the conflict, whose nature will take time to become clear. The chart for Islam had a progressed New Moon 4 weeks earlier in July 2007, which is extraordinary, and confirms the point.
The Composite Chart for Islam and Christianity has Mars at 0.39 Cancer conjunct Saturn and Pluto in Cancer, which is about as heavy as it gets. Pluto will oppose this Mars by transit in Feb 2008, again indicative of a new phase in the conflict between the Christian West and Muslim Middle East.
When Benazir Bhutto was assassinated a few days ago, transiting Mars was very close to this Christian-Muslim composite Mars, and so is descriptive of the tensions between the pro-western Bhutto and the Pakistani Islamists, that led to her murder.
As Pluto moves to oppose the composite Saturn and Pluto in the coming years, Uranus will also square them, at the same time as the Uranus-Pluto square transits the charts of most of the major western powers. This suggests that the development of the conflict between the west and the Muslim world will be an important part of the Uranus-Pluto square, which is the big astrological configuration coming our way. You never know, some sort of accommodation might eventually be reached, it might not be all doom and gloom.
