published his
"Harmonics" in five books dedicated to James I of England. "The first
geometrical, on the origin and demonstration of the laws of the figures
which produce harmonious proportions; the second, architectonical, on
figurate geometry and the congruence of plane and solid regular figures;
the third, properly Harmonic, on the derivation of musical proportions
from figures, and on the nature and distinction of things relating to
song, in opposition to the old theories; the fourth, metaphysical,
psychological, and astrological, on the mental essence of Harmonics, and
of their kinds in the world, especially on the harmony of rays emanating
on the earth from the heavenly bodies, and on their effect in nature and
on the sublunary and human soul; the fifth, astronomical and
metaphysical, on the very exquisite Harmonics of the celestial motions
and the origin of the excentricities in harmonious proportions." The
extravagance of his fancies does not appear until the fourth book, in
which he reiterates the statement that he was forced to adopt his
astrological opinions from direct and positive observation. He despises
"The common herd of prophesiers who describe the operations of the stars
as if they were a sort of deities, the lords of heaven and earth, and
producing everything at their pleasure. They never trouble themselves to
consider what means the stars have of working any effects among us on
the earth whilst they remain in the sky and send down nothing to us
which is obvious to the senses, except rays of light." His own notion is
"Like one who listens to a sweet melodious song, and by the gladness of
his countenance, by his voice, and by the beating of his hand or foot
attuned to the music, gives token that he perceives and approves the
harmony: just so does sublunary nature, with the notable and evident
emotion of the bowels of the earth, bear like witness to the same
feelings, especially at those times when the rays of the planets form
harmonious configurations on the earth," and again "The earth is not an
animal like a dog, ready at every nod; but more like a bull or an
elephant, slow to become angry, and so much the more furious when
incensed." He seems to have believed the earth to be actually a living
animal, as witness the following: "If anyone who has climbed the peaks
of the highest mountains, throw a stone down their very deep clefts, a
sound is heard from them; or if he throw it into one of the mountain
