Neque audiendi sunt qui numero finiunt, quotiens aliquis perfricandus sit: id enim ex viribus hominis colligendum est; et si is perinfirmus est, potest satis esse quinquagies, si robustior, potest ducenties esse faciendum; inter utrumque deinde, prout vires sunt.Neither should we listen to those who would fix numerically how many times a patient is to be stroked; for that is to be regulated by his strength; and if he is very infirm fifty strokes may possibly be enough, if more robust possibly two hundred may be made; then an intermediate number according to his strength.c. 47 CE, Aulus Cornelius Celsus, De Medicina 2.14
