Baum's commentary, which emphasizes the ambiguity of reference in the autobiographical level of this sonnet and the work as a whole, remains critically central.
In more technical terms, we want to note how carefully the poem has been constructed to make connections with previous texts and themes. Each line reaches back to one or another resonant earlier textual moment. DGR arrests our attention to this process of reverse engineering by the literal character of the intertextual links in lines 1-4 (see notes below). The rest of the poem works more loosely and suggestively, freeing the reader to establish connections that are less explicitly anticipated or demanded by the sonnet itself.
The lines are thus micro-instances of what DGR called each sonnet at the outset of the 1881 sequence): moments' monuments that recall, in both senses of the word, dead deathless moments, hours, events. Having been committed to textuality, these moments gain a kind of deathlessness. But that very commitment reciprocally arises as the deathless sign of their irrevocable loss.
Four holograph manuscripts survive. The earliest is probably the sonnet in the Fitzwilliam composite
