The confirmation of Sigismund Augustus was made from the original of Sigismund I.: "exhibitae corara nofais per venerabilem Antonium Radołowskii wladicani Preniisliensem et Samboriensem literae pergameneae inferius scriptae divi Parentis nostri sigillo minori in cordula sericea appenso communitae", while the original privilege of Władysław Jagiełło was already It was submitted to Sigismund I. only in a copy. King Sigismund I. expresses this in the following way in his confirmation: "veniens ad praescntiam nostram reverendus pater Laurentius wladica Premisliensis deplorata ingenti calaraitate, quam ab igne in coudagratione ecclesiae aut sinagogae rittus eorum Rutenici in civitate nostra Premisliensi accepisse se exposuit, iu qua non res tantum et fortuuae there suae quam ecclesiae, sed etiam ornamenta ecclesiastica atqae litterae et privilegia totalliter exustae sunt, quorum quidem exempla veraciter, ut ipse asserebat, ex originalibus literis sereiiissimi olim regis Wladislai avi nostri et ducis Leonis descripta coram uobis exliibuit et instanter peciit, ut tenores eorundem, praesertim vero Wladislai regis, literis nostris inseri atque aulhoritate nostra simul et decreto approbare et confirmare dignareraur. Cuius quidem exempli litterarum serenissimi Wladislai regis tenor talis erat":
Here comes the privilege printed above, followed by these words relating to the issue at hand:
"Post cuius quidem praeinserti exempli exhibitionem ipse wladica ad comproband.uii veritatem teuoris praeinserti literarum obtulit coram nobis literas nobilium districtus Premisliensis sub eorum sigillis, quibus testabantur, se vidłsse eiusmodi litteras originales et earum tenorem intellexisse, quod in huiusiuodi exempio ab ipsius odginali nihil est mutatum aut additum sit, fidem facere. Et insuper dictus wladica paratum se dicebat iure iurando confirmare velle unacum duobus poponibus praeinsertum exemplum veraciter descriptum esse ex literis originalibus per ignem consumptis. Nos itaque attendentes, quod nil aequae sit dignitati principe (sic) christiano, quam eos, qui vel per naufragium vel ignis voraginem aut hostium incursionem rerum et fortunarum suarum iacturam passi sunt et nedum res, sed etiam literas et privilegia bonorum imraobilium atque libertatuni fulcimenta amiserunt, ciementer sublevare litterasque praeinsertas earumque tenorem cum omnibus clausulis et condicionibus iu eis insertis, quatenus in earum usu et possessione wladicae Premislienses fuerunt, innovandas, approbaudas, ratificandas et confirmandas decrevimus, prout innoYamus, approbamus, ratificamus et confirmamus praesentium per teuorem, dando et concedendo praefato patri wladicae Praemisliensi bona omuia supra in tenore literarum descripta oppignorata de manibus tenutariorum et possessorum eorundem redimere et iuridice eliberare".
In view of such circumstances, we must take a closer look at the authenticity of the above printed privilege to see whether it has not been forged or interpolated.
The activation of this privilege is certainly not the activation used in Władysław Jagiełło's office when writing Latin documents. But this document is most certainly only a translation and a very different version of the original Russian text, and this is where the numerous errors in accuracy and countless ungrammatical phrases and linguistic errors arise from. The officials of King Władysław's chancellery did not write in such Latin. Anyway, the most obvious argument is that the above privilege is only a translation, the fact that the translator constantly leaves not only the Latin structure, but even directly from the Latin language, giving entire phrases in a language that is half Russian and half Polish. Therefore, the adaptation of this document is an adaptation of the then Ruthenian, not Latin, documents. It was originally written in Ruthenian and a not very Latin-conscious writer from the office of the Lord of Przemyśl translated it into Latin.
The date won't make us suspicious, but we can't confirm it with anything. Was King Władysław in Sandomierz in the second half of August 1407? We cannot answer this definitively, but we cannot deny it either. We have very few royal documents from 1407, Długosz is exceptionally poor for that year. The royal itiuerarium from that year is therefore very inaccurate and fragmentary. As for the time that concerns us here, we only know that King Władysław was in Łęczyca on July 1, 1407 (Daniłowicz Skarbiec I., 356) and in Lviv on October 13 this year (A. G. Z. IV., 59), and from Długosz we can conclude that he was already in Lviv on October 12 this year (Długosz vol. III., 535 Kraków edition, book X. col. 188 Leipzig edition). Therefore, he could have been in Sandomierz in the second half of August, but there is no proof of this.
