Astrologomania (1624): Carleton, Vicars, and Chamber

Source-Fact Audit — 7 August 2026 (Round 3)

Finding

The 1624 book is securely a George Carleton anti-astrology work published by Thomas Vicars through the Jaggard/Turner imprint. It is relevant to the intellectual network around John Chamber, but its direct connection to Henry Neville rests on a separate probate claim that was not independently re-verified from the manuscript in this pass.

The earlier packet treated John Chamber's will and the 1624 book as a nearly continuous publication history. That is too strong. Even if the reported will reading is correct, it does not prove that Chamber's Arraignement of Astrologie was textually identical with Astrologomania.

Quoted Source Passages: Primary-Print Control

The title page states that the work was:

“Written neere vpon twenty yeares ago, by G.C.”

It also states:

“Published by T. V. B. of D.”

and gives the imprint:

“London, Printed by W. Iaggard, for W. Turner of Oxford. 1624.”

The dedicatory epistle is addressed by Thomas Vicars to his cousin Thomas Carleton of Carleton Hall. Vicars says that the author had been pressed by letters and conversation to permit publication. The Folger, Eton, and EEBO-TCP records identify G.C. as George Carleton and T.V. as Thomas Vicars. Eton's catalogue adds the cautious possibility that Isaac Jaggard completed the printing.

The John Chamber question

The reported reading of John Chamber's will, TNA PROB 11/104/339, names George Carleton of Mayfield and an Arraignement of Astrologie intended to be printed with Chamber's work on the same subject. The same report identifies Henry Neville and Henry Savile as executors.

That manuscript clause was not re-inspected at original resolution in this research pass. It therefore remains an unresolved lead under the project's verification policy. Even after image verification, title similarity and subject matter would establish an antecedent publication plan, not automatic identity with the 1624 text.

Neville relevance

The printed book itself does not name Henry Neville. Its Neville relevance is conditional:

  1. Chamber's will must first be verified line by line.
  2. Neville's executorship would show responsibility for Chamber's estate instructions, not that he edited or transmitted Carleton's text.
  3. A link between the will's Arraignement and Astrologomania would still require textual or bibliographical evidence.

The 1624 imprint is also not evidence of First Folio participation merely because it names Jaggard.

Safe formulation

George Carleton's Astrologomania, written about twenty years before its 1624 publication, was issued by Thomas Vicars through the Jaggard/Turner imprint. A reported clause in John Chamber's 1604 will may point to an earlier Carleton anti-astrology publication plan involving Chamber's executors Henry Neville and Henry Savile, but the manuscript reading and the identity of the proposed work require separate verification.
