Julian Litten has done wonderful research on the English Funeral. The 1890’s marked the heyday of Victorian funerals, before the first world war cast the whole culture of the English funeral into a different, more modest, key. Middle class aspirations, reinforced perhaps by fear of premature burials had popularised embalming and show. Newman, like other personally devout believers, eschewed all this, reasserting the scriptural principle of “dust to dust.” The use of moss is well attested for funerals which involved transporting coffins by cart, as cushioning. It seems suitably pre-raphaelite — they lined the hearse with it for William Morris’ funeral in 1896.
I am not surprised to find Newman’s wishes for his own funeral reflect the images of Keble’s Christian Year. Moss, for Keble is the sign of verdant spring even in Autumn and thus the hope of resurrection. In one poem he describes the kind of place Tractarians would want to be seen dead:
Within some circling woodland wall,There is absolutely no significance in the use of the word “gaily” in line three, not even for Newman and Ambrose St John. Sorry, Peter...
Where bright leaves, reddening ere they fall,
Wave gaily o’er the waters brown.
And let some graceful arch be there
With wreathed mullions proud,
With burnished ivy for its screen,
and moss, that glows as fresh and green
As thought beneath an April cloud —
