knitandpurl "Her lists were made up and closed, so that while she wandered slowly through the Princess's rooms dropping into one ear after another: 'You won't forget tomorrow,' she had the ephemeral glory of averting her eyes, while continuing to smile, if she caught sight of some ugly duckling who was to be avoided or some country squire for whom the bond of a schoolboy friendship had secured admission to 'Gilbert's,' and whose presence at her garden-party would be no gain."

knitandpurl "I felt it in the little square that lay in front of the theatre, in which, in two-hours' time, the bare boughs of the chestnut-trees would gleam with a metallic lustre as the lighted gas-lamps showed up every detail of their structure; and before the ticket attendants, whose selection, advancement and ultimate fate depended upon the great artist—for she alone held power in this administration at the head of which ephemeral and purely nominal managers followed one after the other in an obscure succession—who took our tickets without even glancing at us, so preoccupied were they in seeing that all Mme Berma's instructions had been duly transmitted to the new members of the staff, that it was clearly understood that the hired applause must never sound for her, that the windows must all be kept open so long as she was not on stage and every door closed tight the moment she appeared, that a bowl of hot water must be concealed somewhere close to her to make the dust settle."

brandon.arnold The Greek hêmera (day-break, daybreak, daylight, days, daytime), after the goddess Hemera of 'days', is the base for this beauty of a word. The hemero root was used to mean 'day', which gives the word its metaphorical relationship to all that is temporal or passing, as the passing of a day. Nov 26, 2007
