Father carefully weeding shows his careful, meticulous nature
The clock as a metaphor of passing time - human mortality
The amplified grave ticking of hall clocks
The weeds are vulnerable
Each little weed-root break
Heaney is feeling overwhelming emotion for his father
Next thing he spoke and I nearly said I loved him
A reference to the play ‘Everyman’
if it were nowadays,/This is how Death would summon Everyman
Heaney’s use of assonance to convey his father’s slow movements
Down on his hands and knees beside the leek rig
Image of the hall which uses sibilance to convey peace and calm
mirror glass and sunstruck pendulums
