Review of the two mounds

• rear view → of HCE's two buttocks → cf. when you think you ketch sight of a hind in the previous paragraph

• Revue des deux mondes: (French) Review of the Two Worlds, a major French literary review → File:Book.PNG as both landscape (in which HCE is interred) and letter (in which HCE is described)

• two mounds → ALP's breasts → preceding references to women's clothing ("in their swishawish satins and their taffetaffe tights"), this and the word himples seem to refer to two breasts and nipples; this reference immediately follows images of a woman feeding someone (tending a fire with a bellows and making eggs)

• two mounds: HCE and ALP side-by-side in bed

Commentary

Given the usage of such terms as mudmound to refer to Porter's (or HCE's or the dreamer's, or whoever you want to say's) body, lying asleep, I'm tempted to also view this as a reference just to Porter and his wife (or HCE and ALP or whoever's) sleeping bodies, in much the same way as in the end of the book, they are both described (in the four positions of love-making described there). But here, as only a passing reference.

But, the Porter scene is a silent movie the dreamer imagines himself watching with his family in the cinema! An alternative opinion is that the dreamer is alone in bed, a widower (ALP's closing speech at the end of the book comprises her last words as she dies), who only imagines or dreams that he is sharing the bed with his wife.
