Caligula used to say that Seneca, who was very popular just then, composed "mere school exercises," and that he was "sand without lime."

A word says more than a thousand images. Exercises for the visually inclined: illustrate "appreciation", "humor", "software", "education", "inalienable rights", "elegance", "fact".
Erik Naggum
With regard to lime we must be careful that it is burned from a stone which, whether soft or hard, is in any case white. Lime made of close-grained stone of the harder sort will be good in structural parts; lime of porous stone, in stucco. After slaking it, mix your mortar, if using pitsand, in the proportions of three parts of sand to one of lime; if using river or sea-sand, mix two parts of sand with one of lime. These will be the right proportions for the composition of the mixture. Further, in using river or sea-sand, the addition of a third part composed of burnt brick, pounded up and sifted, will make your mortar of a better composition to use.
Vitruvius
[Quoting Seneca] Cornelia kept her in talk till her children came from school, "and these," said she, "are my jewels."
Robert Burton
Fresh pitsand, however, in spite of all its excellence in concrete structures, is not equally useful in stucco, the richness of which, when the lime and straw are mixed with such sand, will cause it to crack as it dries on account of the great strength of the mixture. But river sand, though useless in "signinum" on account of its thinness, becomes perfectly solid in stucco when thoroughly worked by means of polishing instruments.
Vitruvius
"We class schools, you see, into four grades: Leading School, First-rate School, Good School, and School. Frankly," said Mr Levy, "School is pretty bad..." (Part One, Chapter One)
