Topic: Dudith to Henry Neville (1581): Copernicus, Savile, and Books

0A. Structured Quoted Source Passages

1. The 2019 Edition Identifies the Autograph-Draft Witness

• Source: Andreas Dudithius, Epistulae. Pars VII: 1581-1589, no. 1072; local extracted text Dudithius Epistulae Pars VII 1581 1589 2019:3933.
• Quotation:

"AD HENRICUM NEVILLE"

"Breslau, 7 Aug. 1581"

"Berlin, SB, Depot Breslau, R 253, no 19, f. 10r"

• What it proves: The current text-control edition identifies the letter as a direct Dudith-to-Henry-Neville witness dated 7 August 1581, with an autograph-draft manuscript route.
• Limits: The autograph image has not yet been inspected locally; final diplomatic quotation should be checked against the Berlin witness.

2. Dudith Writes Directly to Neville

• Source: Same 2019 edition, letter no. 1072; local extracted text Dudithius Epistulae Pars VII 1581 1589 2019:3943.
• Quotation:

"mi nobilissime idemque amabilissime Nevelle"

• What it proves: The address is personal and direct to Neville, not merely a later editor's inference from a network context.
• Limits: It proves Dudith-Neville correspondence; it does not by itself prove a particular book purchase or surviving Billingbear copy.

3. Neville Is Asked to Spur Savile on Copernicus and Ancient Mathematicians

• Source: Same 2019 edition; local extracted text Dudithius Epistulae Pars VII 1581 1589 2019:3970.
• Quotation:

"Excita, rogo te... stimula Savile"

"Copernicum veteribus comparandum"

"si credendum est Wittichio"

• What it proves: Neville was directly enlisted by Dudith to push Savile's work on ancient mathematical authorities and Copernicus inside the Wittich/Dudith milieu.
• Limits: This is evidence of intellectual and social participation in a Copernican source network, not proof that Neville himself authored a mathematical work.

4. Neville's Books and Source-Hunting Are Explicit in the Letter

• Source: Same 2019 edition; local extracted text Dudithius Epistulae Pars VII 1581 1589 2019:3975.
• Quotation:

"De libris tuis, quos hic reliquisti"

"sive illud manuscriptum exstet... sive typis editum"

• What it proves: Dudith says Neville had left books with him and asks for mathematical/philosophical material whether manuscript or printed.
• Limits: It does not identify the titles of Neville's books and does not prove that any later Billingbear catalogue item is one of them.

Overview

Andreas Dudith's letter to Henry Neville of 7 August 1581 is one of the strongest direct witnesses for Neville's continental learned network. Dudith writes directly to Neville, then in the Venice orbit, and asks him to spur Henry Savile to work on ancient mathematicians and Copernicus. The letter also refers to Neville's books left with Dudith and asks Neville/Savile to look for mathematical and philosophical books or manuscripts.

This packet is mixed rather than verified because the modern printed edition is strong and gives a witness list, but the autograph manuscript image has not yet been inspected locally.

1. Verified Sourced Facts

• The modern edition Andreas Dudithius, Epistulae. Pars VII: 1581-1589 prints the letter as no. 1072: Dudith to Henry Neville, Breslau/Wroclaw, 7 August 1581.

• The 2019 edition identifies the principal witness as an autograph draft: Berlin, Staatsbibliothek, Depot Breslau, R 253, no. 19, f. 10r. Older Costil shorthand gives this as cod. Rhed. 253, no. 19.

• The letter shows Dudith responding to a courteous letter from Neville and grieving the departure of Neville's party.

• Dudith asks Neville to restore "our Savile" to him if possible, then asks Neville to rouse Savile to work on obscure passages in ancient mathematicians and on Copernicus.

• Dudith explicitly names Paul Wittich in the Copernican comparison, saying Copernicus may be compared with the ancients or, if Wittich is to be believed, preferred to them.

• Dudith refers to books belonging to Neville that Neville had left with him and asks Neville what should be done with them.

• Dudith asks Neville to dig out excellent mathematical and philosophical material, whether manuscript or printed, that Dudith has not yet seen.

• The same-date companion letter to Savile, no. 1071, strengthens the context: Dudith asks Savile to search Venice for Greek mathematical and philosophical material and to examine public, private, and monastic libraries.

• Pietro Daniel Omodeo's MPIWG preprint on Duncan Liddel and Copernican transmission is useful context for the Dudith-Wittich-Breslau mathematical milieu. It independently discusses Dudith's house as a place frequented by English scholars including Robert Sidney, Henry Neville, and Henry Savile, and quotes the same Costil passage from Dudith's 1581 letter to Savile about Ptolemy, Copernicus, and the ancient authorities. Use it cautiously: the preprint gives a wrong Neville date line, ca.1529-1593, and should not be used as a biographical authority for Henry Neville (c.1563-1615).

2. Ken Feinstein Twitter and Blog Information

• Ken's tweet/image trail correctly identified the Costil passage and its importance for Neville, Savile, Copernicus, and the search for a Billingbear Copernicus copy.

• The Billingbear-Copernicus inference must stay separate: this letter proves Neville's direct connection to Copernican mathematical discussion and book exchange in 1581; it does not yet prove that any later Billingbear copy of Copernicus was Neville's personal copy.

3. Quoted Source Text

Excita, rogo te, maiorem in modum atque acrius stimula Savile
ut mihi aliquid elaboret in obscura loca veterum mathematicorum
et Copernicum veteribus comparandum aut, si credendum est
Wittichio, anteponendum.

Working translation: "Rouse, I beg you, and more sharply spur Savile, so that he may work out something for me on the obscure passages of the ancient mathematicians, and on Copernicus, to be compared with the ancients or, if Wittich is to be believed, to be preferred to them."

De libris tuis, quos hic reliquisti ... monebis quid fieri velis.
Interea mihi praeclari aliquid eruite mathematicorum et
philosophicorum sive illud manuscriptum exstet in aliqua
bibliotheca sive typis editum, quod ego nondum viderim.

Working translation: "Concerning your books, which you left here ... you will advise what you wish to be done. Meanwhile, dig out for me something excellent in mathematics and philosophy, whether it exists in manuscript in some library or has been printed, which I have not yet seen."

5. Notes on Access

• Use the 2019 Dudith edition as the current text-control source. It is stronger than the Costil fragment and gives the witness list.

• The autograph image is still the highest-value next step because it would verify the text and clarify any manuscript features, deletions, docketing, or address information.

• This packet should be used as direct evidence for Neville's learned travel, book-search, and mathematical/Copernican network. It should not be used as direct evidence that Neville owned a particular surviving Copernicus volume.

• Do not copy the Neville dates from the MPIWG preprint. Its contextual use is the Dudith-Wittich-Copernicus milieu, not Neville biography.

Additional Fact-Source Notes

• The 2019 Dudith edition remains the controlling text source for this letter until an autograph image is obtained and collated.
• The letter is direct evidence for Neville's learned continental travel, book-search requests, and proximity to Dudith/Savile/Copernican exchange. It is not direct evidence for ownership of a surviving Copernicus volume.
• Book use: use the MPIWG preprint only for Copernican/Dudith-Wittich context, and avoid its Neville chronology because the packet already flags a visible date error.

2026-07-12 Expansion: The Venetian and Paduan Acquisition Network

Reading the adjacent letters as a sequence adds an important institutional setting to Dudith's direct letter to Neville. On 7 August 1581, Dudith told Savile to search every public, private, and monastic library in Venice and said that Girolamo Donzellini and Wolfgang Zündelin would help him. On 10 September, Dudith explicitly told Savile to enter Gian Vincenzo Pinelli's friendship with Neville, because Pinelli possessed an outstanding library and many writings that he would share with them.

Donzellini was already supplying Greek-book lists and locating Philoponus, Simplicius, and other commentators. The direct letter to Neville should therefore be read inside a working acquisition circuit, not as an isolated learned compliment.
