The exercise with the κώρυκος, or leather bag, is described by Oribasius in the following manner: A bag filled with flour or sand was suspended from the top of the house, on a level with the navel; it was then pushed forwards with the hands to the extremity of the rope, and, as it recoiled, the person performing the exercise retreated backwards, so as to escape from it. (Med. Collect. vi, 33.) This exercise is mentioned by Hippocrates. (De Diæta, ii.) Cornarius and the translator of Hippocrates confound it with the follis of the Romans; but Mercurialis clearly shows that they were quite different. The follis was a leather ball, inflated with air; such is the description of it by Cælius Aurelianus: “Follis erat pila magna ex aluta confecta, soloque vento repleta.” Martial represents it as a becoming exercise for boys or old men:
“Ite procul juvenes, mitis mihi convenit ætas,
Folle decet pueros ludere, folle senes.”
(Epigr. xiv, 45.)
They were different from the pila magna and parva; that is to say, the large and small ball. These balls were of different sizes, and were played with in various ways. They are minutely described by Oribasius. (Med. Collect. vi, 32.) See also Horace (Sat. ii, 2), and Martial (Epigr. iv, 15.) See a most learned and accurate account of all these sports in Mercurialis. (De Arte Gymnastica, ii, 4.) Galen has written a treatise on the exercise of the parva pila. To this class of exercises we may refer the pitching of a stone, which is mentioned by Avicenna.
Our author has neglected to make mention of the halteres in this place, but recommends the exercise for the cure of elephantiasis. (iv, 1.) It is described by Galen, who says, it can be made to exercise the spine transversely. (De Sanit. tuend. ii, 11.) The exercise with them is thus described by Potter: “The exercise of leaping they sometimes performed with weights upon their heads or shoulders, sometimes carrying them in their hands; these were called ἁλτῆρες, which, though now and then of different figures, yet, as Pausanias reports, were usually of an oval form, and made with holes, or else covered with thongs, through which the contenders put their fingers.” (Antiquities of Greece, c. 20.) Mercurialis describes them as masses or weights of different materials, and of such a size as that they could be held in the hands. Ropes, too, he adds, were often fastened to them, to hold with. (De Arte Gymnast. ii, 12.) The Pythagoreans were fond of this exercise. (Iamblichus de Vita Pythagoræ, c. 21.)
The funambulatio consisted merely in scaling ropes, which, as we may suppose, was done in various ways. See Mercurialis (iii, 5), and Baccius (de Thermis, viii, 7.)
The ἐκπλεθρίζειν, as Galen and Avicenna explain, consisted in running round the plethrum, or sixth part of the stadium, and always contracting the circle of one’s course, until one stopt in the middle. The πιτυλίζειν, as the same authors explain, consisted in walking upon one’s toes, and tossing one’s hands backwards and forwards.
The cricilasia appears to have been a large hoop, or circle, which was rolled on the ground. Even Mercurialis admits the obscurity of Oribasius’s description of it. (Med. Collect. vi, 26.)
The petaurum was a seat suspended by ropes, in which seat the person taking the exercise sat, and was tossed about by assistants. It is mentioned by Juvenal (Sat. xiv), and Martial (Epigr. xi, 22.)
