“Far from it that the King of Bohemia flee, but to get there lead me where there is greatest uproar of the fight in vigor; the Lord is with us, we must fear nothing, only keep my son diligently.”
Absit, ut rex Boemie fugeret, sed illuc me ducite, ubi maior strepitus certaminis vigeret, Dominus sit nobiscum, nil timeamus, tantum filium meum diligenter custodite.
