Of silence and slow time

As my nuptials are fast approaching, I was looking for an epithalamium for today, but most of them are too long to publish here, and lots of them seem to focus on the bride and the bridal chamber in a way that brings a blush to the bridal cheek. So instead, I chose Keats’ “bride of quietness” and the festal scene depicted on the Grecian Urn. If you want to read the whole thing it's here, but I felt the first two stanzas would do nicely.

Thou still unravish’d bride of quietness,  
Thou foster-child of silence and slow time, 
Sylvan historian, who canst thus express 
A flowery tale more sweetly than our rhyme: 
What leaf-fring’d legend haunts about thy shape      
Of deities or mortals, or of both, 
In Tempe or the dales of Arcady? 
What men or gods are these? What maidens loth? 
What mad pursuit? What struggle to escape?    
What pipes and timbrels? What wild ecstasy?   

Heard melodies are sweet, but those unheard 
Are sweeter; therefore, ye soft pipes, play on; 
Not to the sensual ear, but, more endear’d,  
Pipe to the spirit ditties of no tone: 
Fair youth, beneath the trees, thou canst not leave         
Thy song, nor ever can those trees be bare; 
Bold Lover, never, never canst thou kiss, 
Though winning near the goal—yet, do not grieve;  
She cannot fade, though thou hast not thy bliss, 
For ever wilt thou love, and she be fair!
