can't take out anything

Disce quod ignoras: Marsi doctique Pedonis
saepe duplex unum pagina tractat opus.
Non sunt longa quibus nihil est quod demere possis,
sed tu, Cosconi, disticha longa facis.

Learn what you don't know: one work of (Domitius) Marsus or
    learned Pedo
often stretches out over a doublesided page.
A work isn't long if you can't take anything out of it,
but you, Cosconius, write even a couplet too long.

—Martial

multum in parvo

The phrase multum in parvo has always had a special significance for me. In its terse and compact Latin diction, it exemplifies exactly what it connotes: much in little. The archetype of brevity, however, is not easy to define. Abstraction, conciseness, symbolism, and imaginative potential are basic in the concept. A multiplicity of detail is concentrated into a unified principle, the particular is transformed into the universal, a largeness of meaning is conveyed with the utmost economy of means. This largeness of meaning should be accomplished by a dramatic impact, in a word: insight with a gasp.

—Carl Zigrosser, Multum In Parvo (George Braziller, 1965)
