This is also a first hand account of life, death and medicine in the 16th and 17th centuries, with many surprising details. Of the Black Plague of 1593 (with transiting Saturn in sign of Cancer), Saunders writes, "And you shall understand that this Plague was not infectious, because it came of a cold cause; and there was nothing that bred it so soon as the eating of fresh Herrings and Cucumbers and fruit, and such things as breed slimy Flegm and Water; and most commonly where it took a house, it went round amongst children and servants, that were all of one kind of feeding; and those two years was great plenty of fresh Herrings, and much fruit; and there dyed in the year 1593 eighteen hundred a week, and most of the Doctors of Physick did fly from London, and Dr. Foreman staid by it, and thanks God he saved many." (pg. 154). Includes numerous herbal remedies and medieval medical techniques. Introductions by his contemporaries William Lilly, John Gadbury, Henry Coley and others. One of the great astrology books.
