from The Century Dictionary and Cyclopedia
- n. That from which supplies are drawn; a storehouse; a magazine; a repository.
For, as Proclus saith, Libro de Sacrificio et Magia, it is because the presence of the virtue of the sun, which is the organ and promptuary of all terrestrial and sidereal light, doth more symbolize and agree with a white cock, as well in regard of that colour, as of his property and specifical quality, than with a lion.
Although promptory has not yet found its way into Webster's Third (promptuary, a poorer-sounding variant suggestive of a mortuary, has), it is a worthy and useful addition to the language; for example, good use of it was made in a recent VERBATIM book review [VII, 3, 12].
The word 'promptuary' comes from a Latin word meaning 'storehouse'.
