Dudith's De cometarum significatione and Shakespeare: Source and Transmission Test

Dudith's De cometarum significatione and Shakespeare

Quoted Source Passages

Neville's documented book transaction with Dudith

Dudith's 7 August 1581 letter to Neville says:

De libris tuis, quos hic reliquisti ... monebis quid fieri velis.

Working translation: “Concerning your books, which you left here ... you will tell me what you wish to be done.” The public critical edition is Dudith, *Epistulae* VII. This proves prior personal contact and a book deposit at Dudith's here; it does not name the books or locate Neville on the letter's date.

Explicit English reception in 1599

Edward Topsell prints the source label:

Duditius de cometis

and retells Dudith's distinctive Bochna accident sequence. The exact citation plus the shared local narrative proves that Dudith's comet argument was available for English extraction by 1599. Public text: EarlyPrint TCP A13827.

Round 8 fact ranking

• Direct: the 1579/1580 Dudith comet text; the 1581 Neville-network letters;

Topsell's explicit 1599 citation.

• Probable textual dependence: Howard's 1583 comet discussion, because of

the accumulated argument order and modern-event list, pending page-level image collation.

• Unproved transmission: Dudith or Howard as a Shakespeare source, or

Neville as intermediary.

Notes on Access

The Dudith printed scans, critical edition, Topsell TCP text, Howard TCP text, and Folger play texts have been checked as separate witnesses. Private working files support the audit but are not reader-facing citations. The complete public dossier linked below carries the fuller collation and bibliography.

Finding

No direct Dudith-to-Shakespeare borrowing is proved. The strongest new route is mediated: Henry Howard's Defensative against the poyson of supposed prophesies (1583) repeats the Dudith-Erastus comet argument's structure, causal tests, rainbow analogy, sign taxonomy, royal-body reductio, and a highly specific list of recent rulers' deaths and disasters. The economical hypothesis is Howard's use of the 1579 Dudith-Erastus volume or the 1580 De cometis dissertationes novae.

Howard's warning against assigning errors and stubborn acts of will to planetary influence is a plausible English bridge toward the anti-astrological rhetoric Shakespeare dramatizes in King Lear 1.2. This does not establish that Shakespeare copied Howard, still less that Neville supplied Howard or Shakespeare with the argument.

Neville relevance

Dudith's letter to Tadeáš Hájek of 1 February 1581 was printed at the beginning of Hájek's Apodixis physica et mathematica de cometis. It:

• retracts Dudith's earlier Aristotelian physical location of comets after the parallax work of Hájek, Brahe, Wittich, Gemma, and Maestlin;
• explicitly retains the 1578/1579 rejection of cometary prediction and signification;
• reports Henry Savile's mathematical objection;
• asks Hájek to greet Robert Sidney and dominum Henricum Nevellum, praising the English youths' learning and conduct.

Neville's name is thus present in a printed 1581 comet book at the intersection of new astronomical observation and anti-astrological skepticism. The June Breslau visit and Dudith's direct 7 August letter add personal and material contact. No document yet shows Neville owning the comet volume or transmitting it to Shakespeare.

A separate 22 June letter to Johannes Sambucus identifies him as alter Nevellus, ex antiquissima et illustrissima Nevellorum, Rosae Rubrae, familia (“the other is Neville, from the most ancient and illustrious family of the Nevilles, of the Red Rose”) and calls both Neville and Sidney learned and modest. This strengthens contemporary identification and reputation within the same Breslau network. It does not strengthen the textual case that Dudith's comet argument reached Shakespeare, and the exact origin and political meaning of the Red-Rose wording remain open.

Shakespeare ranking

1. King Lear 1.2: strongest intellectual correspondence—human misconduct is caused by conduct, appetite, and will, then evasively charged to celestial influence. Howard is the likely English bridge; Hyperius (1581) and Chamber (1601) are important independent controls.
2. Julius Caesar 1.2 and 1.3: human agency and skeptical construction of signs are consonant with Dudith but broadly available.
3. Julius Caesar 2.2, 1 Henry VI 1.1, Richard II 2.4, and Hamlet 1.1: share the comet/prodigy–political change–royal death tradition that Dudith himself quotes from Virgil, Lucan, Claudian, Pontano, and historians before refuting it. These are classical-tradition matches, not secure source matches.

English reception

Edward Topsell's Times lamentation (1599), TCP A13827, explicitly cites Duditius de cometis and adapts Dudith's distinctive Bochna accident story. This proves English access by 1599.

Howard's 1583 dependence is not made explicit by a title citation, but its cumulative textual specificity is substantially stronger than topical similarity. It should be presented as probable, pending full image-level collation.

Source-control cautions

• Dudith's 1578/1579 position on signification remained stable even though his 1581 physical cosmology changed.
• The royal-comet motif is ancient and common. Do not treat it as a Dudith fingerprint.
• Preserve King Lear's dramatic irony: Edmund's criticism may be cogent while Edmund is morally deceptive.
• Distinguish three propositions: Dudith's English reception is documented; Howard's dependence is probable; Shakespearean or Neville-mediated transmission is plausible but unproved.
