There are some lines in In Memoriam (I have not the book at hand, but any reader thereof will instantly recollect them), which indicate Tennyson's acquaintance with and appreciation of Jeremy Taylor, who thus expresses the thoughts of the "wild fellow in Petronius," suggested by the sight of a floating corpse.
"That peradventure this man's wife, in some part of the Continent, safe and warm, looks next month for the good man's return or, it may be, his son knows nothing of the tempest: or his father thinks of that affectionate kiss which is still warm upon the good old man's cheek ever since he took a kind farewell; and he weeps with joy to think how blessed he shall be when his beloved boy returns into the circle of his father's arms."—Holy Dying.
Compare with "Sure never moon to evening," &c., in the same poem, and I think the same place:
"Nec nox ulla diem, neque noctem aurora secuta est,
Quæ non audierit mistos vagitibus ægris
Ploratus mortis comites, et funeris atri."—Lucretius, ii. 579.
