Famous quotes containing the words boundaries and/or coverings:

    Women’s art, though created in solitude, wells up out of community. There is, clearly, both enormous hunger for the work thus being diffused, and an explosion of creative energy, bursting through the coercive choicelessness of the system on whose boundaries we are working.
    Adrienne Rich (b. 1929)

    It breedeth no small offence and scandal to see and consider upon the one part the curiosity and cost bestowed by all sorts of men upon their private houses; and on the other part the unclean and negligent order and spare keeping of the houses of prayer by permitting open decays and ruins of coverings of walls and windows, and by appointing unmeet and unseemly tables with foul cloths for the communion of the sacrament.
    Elizabeth I (1533–1603)
