The Secretariat of State to the Nunciature in Spain, 1736

Archivio Apostolico Vaticano, Segreteria di Stato, Spagna 423: eleven ciphered despatches to Abate Guiccioli at Madrid during the rupture over Spanish recruiting in Rome (DECODE R26, R179–R188).

George Lasry reconstructed the key and deciphered all eleven in 2020, except for the code groups: his key leaves all 166 of them without a value. Starting from his decipherment, 46 groups were recovered here from context.

Summary. The catalogue listed ten DECODE records of 1736 papal despatches to Madrid with contents unknown: “what the cipher hides is not known.” Every record carries George Lasry’s reconstructed key “ASV - S423” (24 October 2020) and his segmented decipherment of all eleven items, 14 July to 22 December 1736. So the key had been recovered and the letters deciphered before this project looked at them. His key covers only the two-digit elements, the letters and syllables. The 166 distinct four-digit nomenclator groups, 708 tokens and 7.9 per cent of the text, are printed in his decipherment as bare numbers, and they carry the names and most of the key words. Unlike the Spagna 364D key of 1718, this nomenclator is not alphabetical, so values were fixed from context alone. A value was kept only when it gives sense at every occurrence. 46 groups were recovered, covering 424 of the 708 tokens; the share of the text with a value goes from 90.6 to 95.3 per cent. 120 groups remain open, most of them seen once or twice.

01 The dossier and what was on the records

Spagna 423 is described in the Vatican index (i. 1025) as “Lett. originale e ciffre della Segretaria alla nunziatura, dal 7 gennaio 1736 al 29 dicembre 1736”. The catalogue took its “7 Jan 1736” from that heading, but the ciphered items run from 14 July to 22 December 1736. The clear dates on the transcriptions are 14 and 21 July, 4 August, September, 29 September (two), 6 October, 15 and 22 December. The dockets name the addressee as “Sig. Ab. Guiccioli, Madrid”. There are eleven items (423/1–11) across ten DECODE records.

Each record carries three attachments: the item’s raw digit transcription (Matt F and NiLan, 2015–17); Lasry’s key, “#KEY: reconstructed · ASV - S423 · George Lasry · October 24, 2020”; and a single file holding his decipherment of the whole dossier, the ciphertext split into elements with the plaintext aligned underneath.

02 The system

R179, Rome, 21 July 1736, the top of the page: below the dateline, an undivided stream of digits in which two-digit elements, 7 as a null and four-digit nomenclator groups beginning with 1 run together without separators.

03 Method

Lasry’s aligned decipherment was parsed into 9,001 tokens, and each unvalued group was listed with every context it appears in. In 1718 the nomenclator ran alphabetically and the neighbouring values bracketed each gap. That does not work here: 1222 is -mente, 1245 -zione, 1882 Spagna, 1935 V.S., in no order. So each value had to be inferred from its contexts, and it was accepted only when it gave sense in all of them. The frequent groups are anchored many times over: 1222 in 44 places (somma-, diffusa-, pari-, facil-, destra-, minuta-mente), 1655 = N.S. in 21 (“N.S. è rimasto sommamente amareggiato”, “le giuste istanze di N.S.”).

05 A sample: the opening of 423/1 (14 July 1736)

Lasry’s letters with the recovered groups applied, lightly normalised; square brackets mark groups still open:

… a quanto diffusamente [1853] in piano stimo maggior di aggiungere in [1846] de’ suoi numeri degli [1953] passato. N.S. è rimasto sommamente amareggiato nell’udire che codesto [Mons.?] Molina, scordatosi degli obblighi di Vescovo e regolare, si unisca in questa [1368] [1201] dei tumulti contro la S. Sede, e per iscusa di una condotta al giudizio di ognuno molto irregolare si ponga [1389] in vista l’affare […] e le grazie accordate … le altrui violenze non dovrebbero mai servire di esempio …

His Holiness is “most bitterly grieved” that Molina, forgetting his duty as a bishop, joins in the tumults against the Holy See. Gaspar de Molina y Oviedo, Bishop of Málaga and Governor of the Council of Castile, led the Spanish side of the 1736 dispute.

06 What the despatches are about

In spring 1736 Spanish recruiters took men by force in Rome and the Papal State (“arrolamenti”, “ingaggiature”, “arrolatori”), which set off riots in Trastevere and at Velletri. Spain and Naples broke with Rome. The despatches deal with the tumults “contro la S. Sede”, Cardinal Acquaviva, the Duke of Montemar, Bishop Molina, the expulsion of the nuncio and the pensions at the Court of Naples. From October they turn to the Dataria, the padronato reale over benefices, the “Regalista” doctrines of the Madrid junta, Briefs to the King and Queen, and the nomination to cardinals’ hats (“col maggior numero di cappelli”).
