Sublime on the towers of my skiey bowers

A bit of a bleurggh day yesterday. Son#1 went home, the rain didn't stop, the house felt horribly empty, the rain got even worse and we missed a house warming party, nervous about crossing the mountain in lashing rain, mist, floods and increasing winds. Sensible but boring - sorry Robert and Finola. I blipped the cat and some Roses and then the mojo vanished altogether. Oh well. We stayed at home and got stuck into Borgen3.

A better day today. The sun shone and we went for a very bracing walk around the headland. So many birds - turnstones, cormorants, egrets, oystercatchers, curlew, snipe. No otter though - his rock was submerged in foaming waves. The sky was mackerel and about 70 blips were blipped but on my way to get supplies in Bantry this rather dramatic cloud loomed into view. It's amazing how many toots and waves you get when snapping away on the side of the road. Or maybe it was my parking.

Brownie points if you can tell me from which poem I've borrowed the title.
