An existing letter of Erasmus, written in the year of Froben's death, gives an idea of his life and an estimate of his character; and in it Erasmus mentions that his grief for the death of his friend was far more distressing than that which he had felt for the loss of his own brother, adding that "all the apostles of science ought to wear mourning".
Dochovaný dopis od Erasma, napsaný v roce Frobenovy smrti, poskytuje souhrn jeho života a popis jeho povahy; a v něm Erasmus zmiňuje, že jeho trápení nad smrtí přítele bylo mnohem hlubší než to, které cítil u ztráty svého bratra a dodal, že všichni apoštolové vědy musí truchlit.
