Institutio Oratoria

The Greeks call this essential basis στάσις, a name which they hold was not invented by Hermagoras, but according to some was introduced by Naucrates, the pupil of Isocrates, according to others by Zopyrus of Clazomenae, although Aeschines in his speech against Ctesiphon [*](§ 206.) seems to employ the word, when he asks the jury not to allow Demosthenes to be irrelevant but to keep him to the stasis or basis of the case.

The term seems to be derived from the fact that it is on it that the first collision between the parties to the dispute takes place, or that it forms the basis or standing of the whole case. So much for the origin of the name. Now for its nature. Some have defined the basis as being the first conflict of the causes. The idea is correct, but the expression is faulty.
