Thomas Digges, Copernican Astronomy, Troilus, and Hamlet

Mixed Needs Review source map packet

Topic: Thomas Digges, Copernican Astronomy, Troilus, and Hamlet

Current controlled claim: the Digges/Neville-adjacent family and intellectual-network lane exists, while the Shakespeare textual-source lane remains a source-map lead.
Do not say the Troilus metaphor is taken directly from Digges until the Digges witness and the Troilus/Hamlet passages are extracted and compared.

The Rosencrantz/Guildenstern name lead is now routed through tycho_brahe_portrait_rosencrantz_guildenstern_hamlet.md.
This packet should keep Digges separate: its job is to test whether Thomas Digges's astronomical language and diagrams supply controlled comparanda for Troilus and Cressida and Hamlet.
The Tycho packet should carry the portrait-print lane: Tycho to Thomas Savile, the 1590 engraved likeness, Rogers/Dee/Digges circulation, and the guarded Rosenkrans/Gyldensteren-to-Hamlet source hypothesis.

The existing Dudley Digges packet records the family route: Thomas Digges married Anne St. Leger, daughter of Ursula Neville, creating a specific collateral Neville-family connection.
The existing John Chamber packet records a local source claim that Thomas Digges served on a 1583 calendar-reform commission with Henry Savile and John Chamber.
The current Troilus/Thorpe packet already preserves the Ken Feinstein lead that an extended metaphor in Troilus and Cressida may draw on Thomas Digges or related mathematical/astronomical material.
A Penn State research article discusses the argument that Hamlet's "king of infinite space" language engages Thomas Digges's model of an infinite universe. This is context, not proof of Neville authorship.
The packet therefore has two distinct lanes: a verified Digges/Neville-adjacent family and intellectual-network lane, and a still-lead-level Shakespeare textual-source lane.
BRO sweep, 2026-05-30: no direct Digges, Copernican, astronomical, or calendar-reform witness was found in [local source path removed]. BRO does not currently strengthen this packet. Keep the family route in the Dudley/Leonard Digges packets and the textual-source route in EEBO/page-image comparison.

Ken's Troilus Twitter thread states that the extended metaphor in Troilus and Cressida is taken directly from Thomas Digges. Current hardening note: preserve this as tweet-level claim language until direct comparison is built.
The same thread connects Hamlet's "king of infinite space" language to the Digges diagram and links the Guildenstern name to Tycho Brahe.
Ken also connects this to Neville's 1599 portrait astronomy symbolism and to the Digges family connection through Dudley and Leonard Digges.
The direct textual comparison has not yet been built into the AI topics corpus; this packet is meant to create that workspace.

"This extended metaphor in Troilus and Cressida is taken directly from Thomas Digges."
"Hamlet's comments about being the king of infinite space seem to combine these two ideas from the Digges book."
"Thomas Digges' eldest son Dudley was a close friend of Henry Neville; and youngest son Leonard wrote a poem for the First Folio."

This packet should not claim a completed source study yet. Its purpose is to force a direct Digges-to-Shakespeare comparison rather than leaving the point as a Twitter assertion.
The highest-value next step is to extract Thomas Digges's astronomical text from EEBO or a page-image witness, then compare it line-by-line with Troilus and Cressida and Hamlet.
BRO update, 2026-05-30: no BRO hit promotes the astronomy claim. The current risk remains over-claiming from tweet-level comparison before the Digges source text is extracted.

Local EarlyPrint identifies A20458 as Leonard Digges's 1571 Pantometria, "lately finished by Thomas Digges his son" and augmented by Thomas with a mathematical treatise on the Platonic bodies. Do not cite it as simply Thomas Digges's own text without that qualification.
Local EarlyPrint identifies A08351 as Robert Norton's 1624 Of the art of great artillery, preserving definitions, questions, and theorems attributed to Thomas Digges concerning great ordnance. This is useful for technical and ordnance context, but it is too late to serve as a Shakespeare source without careful qualification.
The direct Digges-to-Troilus and Digges-to-Hamlet comparison still needs to be built from extracted source text and play text. This pass did not complete that comparison.
Book-safe formulation: verified Digges/Neville family and intellectual-network adjacency; source-map lead for Shakespearean astronomical language; no completed source claim yet.
