At which point he once turned his eyes upon me,
Hyperborean, beyond-the-north-wind blue,
Two peepholes to the locked room I saw into
Every time his name was mentioned, skimmed
Milk and ice, swabbed porcelain, the white
And chill of tiles, steel hooks, chrome surgery tools
And blood dreeps in the sawdust where it thickened
At the foot of each cold wall. And overhead
The little, pendent, teat-hued infant parts
Strung neatly from a line up near the ceiling—
A toe, a foot and shin, an arm, a cock
A bit like the rosebud in his buttonhole.

Poeta doctus Peter Levi says
Sanctuaries of Asclepius (called asclepions)
Were the equivalent of hospitals
Section 2 focuses on the speaker’s experience as he is older- the language and references used here are much more sophisticated and adult, and the speaker’s tone is much more authoritative. However, structurally it is very similar to Section 1. 
 Both feature a mythologised figure who the speaker looks up to (Dr Kerlin becomes Peter Levi), a set of healing rituals (Dr Kerlin’s bag, pilgrimages to Lourdes & Epidaurus), and a moment of final epiphany & rebirth (eye contact with Dr Kerlin, coming out of the fainting spell). 
 These parallels show that although the nature of wonder and belief changes as one ages, it is ever-present.
