Sibley, Manoah (17571840)
Swedenborgian minister and astrologer, born in Bristol, England,
on August 20, 1757, the younger brother of astrologer
Ebenezer Sibley. Unlike his college-educated brother, Manoah
Sibley had to study on his own from age 11, but through his
teens he mastered several languages, which, along with shorthand,
he taught through the 1760s and 1770s. He married in
1780 and opened a bookshop, which he and his wife managed.
Sibley dropped his own work to align with the church that had
been established in London by Robert Hindmarsh. Swedenborgs
teachings were received as the end of his spiritual quest
and by Easter of the next year he began preaching. He was ordained
in 1790. Hindmarsh, a former Methodist, modeled his
church on that which was familiar to him. Sibley found his approach
too restrictive and in 1793 he left to found his own Swedenborgian
congregation. He preached weekly for the next
Apart from pioneering the beliefs of Emanuel Swedenborg
in England, Sibley is most remembered today for his publication
of translations of the writings of Claudius Ptolemy and
Placidus. Sibleys translation of the Tetrabiblos (four books) of
Ptolemy, the major work from which Western astrology developed,
appeared in 1786, and the writings of Placidus, whose
system of arranging the astrological houses would come to
dominate astrology in the next century, appeared in several
volumes in 1789 and 1790.
Astrologers hail Sibley for making these works available and
note their importance in directing the astrological revival in
England in the nineteenth century. Critics have charged Sibley
with theft, first of Whalleys earlier translation of the Tetrabiblos,
and then of a manuscript of a translation of the writing of Placidus.
All of his books are full of errors that, in spite of his linguistic
accomplishments, he could not correct because he did
not have copies of the Latin originals.
Whatever the problems with the translations, Sibley went on
to an even more prestigious career with the Bank of England,
beginning in 1797, and was appointed principal of the Chancery
Office in 1815.
Sibley died in December 1840 in London.
