Analysis of Beneath A Photoraph

Phoebus, who taught me art divine,
Here tried his hand where I did mine;
And his white fingers in this face
Set my Fair's sigh-suggesting grace.
O sweetness past profaning guess,
Grievous with its own exquisiteness!
Vesper-like face, its shadows bright
With meanings of sequestered light;
Drooped with shamefast sanctities
She purely fears eyes cannot miss,
Yet would blush to know she IS.
Ah, who can view with passionless glance
This tear-compelling countenance!
He has cozened it to tell
Almost its own miracle.
Yet I, all-viewing though he be,
Methinks saw further here than he;
And, Master gay! I swear I drew
Something the better of the two!
