The story goes on to say that in England he met a woman (Susanna Valeria) "so abundant, so favored by Venus that nothing else would do but that he have her to wife." At this point the story skips over a small matter, intentionally or not, that might well explain Thomas' future apparent inability to settle in one place, even as a renowned and successful scholar. The dedication of his edition of Rosinus' "Antiquitatum romanarum corpus absolutissimum" to King James I, a Protestant (the king of the King James Bible), even though he, Dempster, was a Catholic, had won him an invitation to the English court; and in 1615 he went to London. There James I appointed him historiographer royal.
