But to come again unto Apelles, this was his manner and custom besides, which he perpetually observed, that no day went over his head, but what businesse soever he had otherwise to call him away, he would make one draught or other (and never misse) for to exercise his hand and keepe it in use, inasmuch as from him grew the proverbe, Nulla dies sine linea, i.e. Be alwaies doing somewhat, though you doe but draw a line. His order was when he had finished a piece of work or painted table, and layd it out of his hand, to set it forth in some open gallerie or thorowfare, to be seen of folke that passed by, and himselfe would lie close behind it to hearken what faults were found therewith; preferring the judgment of the common people before his owne, and imagining they would spy more narrowly, and censure his doings sooner than himselfe: and as the tale is told, it fell out upon a time, that a shoomaker as he went by seemed to controlle his workmanship about the shoo or pantofle that he had made to a picture, and namely, that there was one latchet fewer than there should be: Apelles acknowledging that the man said true indeed, mended that fault by the next morning, and set forth his table as his manner was. The same shoomaker comming again the morrow after, and finding the want supplied which he noted the day before, took some pride unto himselfe, that his former admonition had sped so well, and was so bold as to cavil at somewhat about the leg. Apelles could not endure that, but putting forth his head from behind the painted table, and scorning thus to be checked and reproved, Sirrha (quoth hee) remember you are but a shoomaker, and therefore meddle no higher I advise you, than with shoos. Which words also of his came afterwards to be a common proverbe, Ne sutor ultra crepidam.
Pliny (Natural History).
Apelles, the greatest painter of antiquity. The two proverbs mean: “No day without a line,” “A cobbler should stick to his last.” Pantofle, sandal; latchet, the thong fastening the sandal; painted table, panel picture; controlle, find fault with.
Have you seen but a bright lily grow,
Before rude hands have touched it?
Have you marked but the fall of the snow,
Before the soil hath smutched it?
