Note 483 — INDEX TO THE NOTES.
Reading edition
night-foundered; benighted, lost in the darkness. Radically, ‘to founder’ is to go to the bottom (Fr. fondrer; Lat. fundus, the bottom), hence applied to ships; it is also applied to horses sinking in a slough. The compound is Miltonic (see Par. Lost, i. 204), and is sometimes stigmatised as meaningless; on the contrary, it is very expressive, implying that the brothers are swallowed up in night and have lost their way. ‘Founder’ is here used in the secondary sense of ‘to be lost’ or ‘to be in distress.’
