De Agricultura

Those, then, who permit the flock committed to their charge to satiate themselves all at once with all the things that they desire, we must call keepers of sheep; but those, on the contrary, we should entitle shepherds, who supply their flocks with only so much as is necessary and proper for them; cutting off and utterly rejecting all superfluous and useless extravagance and abundance, which is not less injurious than want and deficiency, and who guard with great prudence against the possibility of the flock becoming diseased through their want of care and indolence, praying that those diseases, which at times are liable to attack flocks from external causes, may not visit theirs.
