Christoph HEYLL to Ioannes DANTISCUS Elbing (Elbląg), [1539]-08-26, CIDTC IDL 6235⌋: Tuam igitur, princeps, illustrem eandemque reverendissimam gratiam tum doctrina et rerum usu eximiam quamquam innumera summorum in Christiana republica heroum, papae, imperatoris regumque monumenta tuo merito parta non mediocriter exornant, propria tamen, reverendissime praesul, virtus tua humanitasque, id est, litterarum in te amplitudo (quantum illum tibi splendorem accersivit) summopere videtur commendare. Quae me, Praesul Illustrissime, res movet, ut gratiae tuae, nisi recuset, duos cupiam Aelius Galenus (Claudius Galenus, Galen of Pergamon) (*129 – †217), Greek physician and philosopher⌊GaleniAelius Galenus (Claudius Galenus, Galen of Pergamon) (*129 – †217), Greek physician and philosopher⌋ principis medici libellos, Latinitate utcumque donatos, dedicare, rogoque hanc ob rem [clemen]tia tua me ea de re certiorem reddat ac sibi persu[a]deat nihil mihi esse gratius, quam tanto princip[i] tantisque, ut praedicatur, dotibus ornato placere. None of Heyll’s translations of Aelius Galenus (Claudius Galenus, Galen of Pergamon) (*129 – †217), Greek physician and philosopher⌊GalenAelius Galenus (Claudius Galenus, Galen of Pergamon) (*129 – †217), Greek physician and philosopher⌋’s works that are known to us was dedicated to Dantiscus. It can be assumed that the translation mentioned was not published at that time. Probably Heyll, writing about two of Aelius Galenus (Claudius Galenus, Galen of Pergamon) (*129 – †217), Greek physician and philosopher⌊GalenAelius Galenus (Claudius Galenus, Galen of Pergamon) (*129 – †217), Greek physician and philosopher⌋’s books (duos [...] Galeni principis medici libellos), had meant Duo libri, unus de plenitudine, alter de curativa sanguinis missione, ad custodiam sanitatis utilissimi, published in 1558 in Gdańsk (Danzig, Dantiscum), city in northern Poland, on the Bay of Gdańsk at the mouth of the Vistula, on the Baltic, the biggest and wealthiest of the three Great Prussian Cities (Gdańsk, Thorn (Toruń), and Elbing (Elbląg)) with representation in the Council of Royal Prussia; a member of the Hanseatic League⌊GdańskGdańsk (Danzig, Dantiscum), city in northern Poland, on the Bay of Gdańsk at the mouth of the Vistula, on the Baltic, the biggest and wealthiest of the three Great Prussian Cities (Gdańsk, Thorn (Toruń), and Elbing (Elbląg)) with representation in the Council of Royal Prussia; a member of the Hanseatic League⌋.
