Nauticum astrologicum: or, The astrological seaman 1710

[PoD]

Just found a great book while looking through Google books:

Nauticum astrologicum: or, The astrological seaman: directing merchants, mariners, captains of ships, ensurers, &c. how (by God's blessing) they may escape divers dangers which commonly happen in the ocean. Unto which is added a diary of the weather for XXI years together, exactly observed in London, with sundry observations thereon by John Gadbury (1710)

That's a wild piece and a cool find. Especially the page for calculating the profitability of a voyage by the day of departure according to the stars. I have enough trouble with the basic math of plotting a course.

Astrology was also an important part to some doctors in the Humoral Theory. (You "should not bleed when the stars are thus" and other such nonsense.)

One can't help but wonder what they'll look back on in the future and say, "They actually believed thus and so at this time in history."

My parents still believe that you can catch a cold if you don't wear a coat. Astrology of the Rhinovirus.
