1658
"Mercury to his own place, makes the Native famous by his own industry: he is honoured and preferred by the commendations of ingenious men: he gains much by Science, Merchandise; and lives friendly with his Brethren and Kindred. But if he be ill placed there, it portends the contrary"

A New and Complete Illustration of the Occult Sciences
Ebenezer Sibly
1784
"He completes his revolution, or traverses through the twelve signs of the zodiac, in eighty-seven days and twenty-three hours of our time nearly; which is the length of his year. But being seldom seen, on account of his proximity to the sun, and having no spots visible on his surface or disk, the time of his rotation upon his own axis, and the length of his days and nights, are as yet unknown to us. His distance from the sun is computed to be thirty-two millions of miles, and his diameter two-thousand six hundred. He moves round the sun at the rate of ninety-five thousand miles every hour; and receives from that luminary a proportion of light and heat almost seven times as great as that of the earth. At the times he becomes visible, he appears of a bright silver colour; though generally faint and duskish to the naked eye. His mean motion is fifty-nine minutes and eight seconds, and sometimes sixty minutes; and his diurnal motion is most times one hundred minutes a-day. His greatest latitude, both north and south, is three degrees thirty-three minutes. His exaltation is in fifteen degrees of Virgo; his detriment in Sagittarius and Pisces, and his fall in fifteen degrees of Pisces. He is retrograde twenty-four days; and is stationary one day before and one day after retrogradation"
