Decker, John

, a pious and learned Jesuit, was born about 1559, at Hazebruck in Flanders, and taught philosophy and scholastic theology at Douay, and afterwards at Louvain. He was then sent on an embassy into Stiria, and became chancellor of the university | of Gratz, where he died in 1619, aged 69. His principal work treats of the year of the birth and of the death of Christ. It is entitled, “Velificatio, seu theoremata de anno ortds ac mortis Domini; cum tabula chronographica, a capta per Pompeium lerosolyma, ad deletam a Tito xirbem;” Gratz, 1606, 4to. He was a man of profound erudition, and had acquired great skill in chronology. ¹
