Henry Coley
English astrologer and mathematician

Henry Coley (18 October 1633 – 30 April 1704) was an astrologer and mathematician, and amanuensis of William Lilly.
Early life and career
Coley was born, as shown in an inscription round a portrait of him by Robert White, found in some of his works, on 18 October 1633 in Oxford. His father was a joiner. In 1648 he became a clerk in the Parliamentary army; in 1654 he moved to London and worked as a ladies' tailor in Gray's Inn Lane.
In 1656 he married and they had one child; in 1660, after his wife's death, he married again; their son born in 1661 died soon after birth. He taught himself mathematics, astrology, Latin and French. From 1663 he lived in Baldwins Gardens, where he taught astrology and mathematics, and received clients. By the 1670s he had a flourishing practice.
In 1669 Coley published Clavis Astrologiæ Elimata; or a Key to the whole Art of Astrology, new filed and polished. It was well received.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Henry Coley”, the useful work is to connect “english astrologer and mathematician” to the records capable of establishing context and consequence.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Feb 2, 2025. The linked authority identifier is Q18528469. VIAF identifies the subject as 281137997. The Library of Congress control number is n84177453. 1 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1633, 1704, 1648 and 1654.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
