Salutem et servitutis meae commendationem.

Fortassis male meam tam diuturnam absentiam a Dominatione Vestra Reverendissima accipi metuebam atque ob id has turbulentas manu trepidante cerebro disperso congessi, petens me quam optime purgatum haberi apud Dominationem Vestram. Neque enim meae neglegentiae imputari iuste potest, quod vel ipse Ioannes Campensis (Jan van Campen, Ioannes de Campo) (*1491 – †1538), Netherlandish classical philologist and Hebraist, author of a paraphrase of the Book of Psalms from Hebrew to Latin and a Hebrew grammar, in 1531 lecturer at the Collegium Trilingue of Louvain University (CE, vol. 1, p. 255-256)⌊CampensisIoannes Campensis (Jan van Campen, Ioannes de Campo) (*1491 – †1538), Netherlandish classical philologist and Hebraist, author of a paraphrase of the Book of Psalms from Hebrew to Latin and a Hebrew grammar, in 1531 lecturer at the Collegium Trilingue of Louvain University (CE, vol. 1, p. 255-256)⌋ (cui Dominatio Vestra plurimum confidit) atque alii non parvi ponderis testabuntur. Sed, ut demum brevissimis causam absolvam, venissem die Sabbati proxime transacta, nam tum expeditus quidem fui negotiis mihi commissis, sed impeditus morbo certe non levi, qui me corripuerat vix a limine mansionis Dominationis Vestrae digressum atque huc usque vana spe detinuit. Nunc ostenso medicis lotio dicunt illi me in ambiguo esse sive in discrimine vitae, nam hepar meum usque adeo incensum est, ut vix restingui possit, et si proficiscendum mihi sit vel paululum, maius imminere periculum. Mitto igitur ad Dominationem Vestram Reverendissimam cumulum librorum, quos in catalogo nostro mihi praescripserat, assignato pretio, desunt tamen quattuor vel quinque, quos hic invenire non potui, et, si placet Dominationi Vestrae pretium, potest eos servare. Ego vero cogor adhuc 4-r vel quinque diebus hic decumbere, donec videro, quid Deus mecum agere velit, neque enim diu durare potest, quin me vel Deo vel vitae reddet. Si vero Dominatio Vestra mihi pro me, medicis et medicinis vellet mittere unum vel duos Philippeos, vel quantum ei placeret, bene mecum ageret, et si morior, gratiam a Deo accipiet; si vivam, non ero ingratus.
