If his constantly-changing life can be said to have had a turning-point, it occurred in 1633, when his wife died suddenly. The death of the lovely Venetia was the signal for a great outburst of vile poetry on her beauty and merits. Ben Jonson, her loyal friend and Kenelm's, wrote several elegies, one of them the worst. Vandyck painted her several times; and so the memory of her loveliness is secure. As to her virtues, amiability seems to have been of their number. "Unmatcht for beauty, chaster than the ayre," wrote one poet. When they opened her head it was discovered she had little brain; and gossip attributed the fact to her having drunk viper-wine--by her husband's advice--for her complexion. This sounds absurd only to those who have not perused the _Receipts in Physick and Chirurgery_. Little brain or not, her husband praised her wits. Ben Jonson wrote with devotion of her "who was my muse, and life of all I did." Digby imitated his father-in-law who, in similar circumstances, gave himself up to solitude and recollection. His place of retirement was Gresham College. Do its present students remember it once housed a hermit who "wore a long mourning cloake, a high crowned hat, his beard unshorne ... as signes of sorrowe for his beloved wife"? There "he diverted himself with chymistry and the professor's good conversation." He had "a fair and large laboratory ... erected under the lodgings of the Divinity Reader." Hans Hunneades the Hungarian was his operator. But another influence was at work. For the first time his mind turned seriously to religion. Romanist friends were persuading him to his father's faith. His old tutor Laud and other Protestants were doing their best to settle him on their side. Out of the struggle of choice he came, in 1636, a fervent and convinced Catholic. He was to prove his devotion over and over again; but I fear that Catholics of to-day would view with suspicion his views on ecclesiastical authority. In his dedication of his _Treatise on the Soul_ to his son Kenelm, there is a spirited defence of the right, of the intelligent to private judgment in matters of doctrine. Nevertheless, his Catholicism, though rationalist, was sincere, and he spent much energy in propaganda among his friends--witness his rather dull little brochure, the _Conference with a Lady about Choice of Religion_ (1638), and his correspondence with his kinsman, Lord Digby, who did, indeed, later, come over to the older faith. Ere long he earned the reputation of being "not only an open but a busy Papist," though "an eager enemy to the Jesuits."
