The rubyand amethyst eyes of anemones Glow through me, fiercer than stars.

-Brasch, Charles
Home Ground (1974),'Night Cries, Wakari Hospital:  Winter Anemones'.

Full on this casement shone the wintry moon, And threw warm gules on Madeleine's fair breast, As down she knelt for heaven's grace and boon; Rose-bloom fell on her hands, together prest, And on her silver cross soft amethyst, And on her hair a glory like a saint: She seemed a splendid angel, newly drest, Save wings, for heaven.
