§7#1Τούτων ἤδη γεγραμμένων, καί τισι τῶν ἑταίρων ἐκδιδομένων, ἢ ἀξιωσάντων ἑτέρων μαθεῖν, ὅπως ἂν ᾖ τοῦ διαγράμματος, ἐγὼ παραχρῆμα τοῖς προβάλλουσιν ἀποκρίνομαι τὸ πλῆθος τῶν τύπων.
These things having already been written, and having been distributed to some of the companions, or others having demanded to learn how it stands with the diagram, I immediately answer to those who pose the questions the multitude of the types.
ἔστιν οὖν ἡ μέθοδος οὐχ ἑτέρου τινὸς γένους, ἀλλ’ ὑποπεπτωκυῖα τῇ προτέρᾳ.
Therefore, the method is not of some other kind, but subordinate to the former one.
πεισθήσῃ δὲ καὶ αὐτὸς οὕτως ἔχειν ἀναμνησθεὶς πρότερον ἀεί τε πρόχειρον ἔχων τὴν μνήμην αὐτῶν, ὡς ἡμέραν ὀνομάζομεν ἐν τῷ χρόνῳ τούτῳ τὸν συγκείμενον χρόνον ἔκ τε τῆς ἡμέρας καὶ τῆς νυκτὸς, ὅπερ ἔνιοι προσαγορεύουσι νυχθήμερον.
And you yourself will be convinced that it is so, if you first recall and always keep handily in your memory of them, that in this context we call "day" the time composed of both day and night, which some address as a "nychthemeron" (night-and-day).
οὕτω γοῦν καὶ τὸν ἐνιαυτὸν εἶναι λέγομεν ἡμερῶν τξε΄ καὶ τετάρτου.
In this way, at any rate, we also say that the year is of three hundred and sixty-five days and a quarter.
μιᾶς μὲν οὖν ἡμέρας τέτταρες ἐπὶ ταῖς κ΄ ὧραι γίγνονται, δυοῖν δὲ ὀκτὼ καὶ τετταράκοντα, τριῶν δὲ δύο καὶ ἑβδομήκοντα· τὰ δὲ ὀνόματα τοῖς τύποις οὐκ ἀπὸ τῶν συμπληρουμένων ἡμερῶν ἐστιν, ἀλλ’ ἀπὸ τῆς ἀνταποδόσεως τοῦ παροξυσμοῦ.
Thus, of one day there are twenty-four hours, and of two, forty-eight, and of three, seventy-two; but the names for the types are not from the completed days, but from the recurrence of the paroxysm.
τριταῖον μὲν ὀνομάζομεν ᾧ διὰ τρίτης ἡμέρας ὁ παροξυσμὸς γίγνεται, δυοῖν μεταξὺ δηλονότι καὶ συμπληρωθεισῶν· τεταρταῖον δὲ ᾧ κατὰ τετάρτην, τριῶν κᾀπὶ τούτῳ μεταξὺ συμπληρουμένων ἡμερῶν, ἐπί τε τῶν ἄλλων ἀνάλογον· ὥσθ’ ὅταν εὕρῃς περίοδον τύπου τεττάρων ἡμερῶν, πεμπταῖον ἐρεῖς αὐτὸν, οὐ ταὐτὸν γάρ ἐστι διὰ πέμπτης τε παροξύνεσθαι καὶ πέντε ἡμερῶν ἔχειν περίοδον.
For we call "tertian" that in which the paroxysm occurs every third day, with two days clearly having been completed in between; and "quartan" that in which it occurs on the fourth day, with three days completed in between in addition to this; and analogously for the others; so that when you find a period of a type to be of four days, you will call it a "quintan", for it is not the same thing to have paroxysms every fifth day and to have a period of five days.
ἐν μνήμῃ τοίνυν θέμενος ταῦτα, πάλιν ἀναμνήσθητί μοι τῆς εἰρημένης ἔμπροσθεν ἐπὶ τῷ διαγράμματι μεθόδου.
Having put these things, therefore, in your memory, recall for me again the method mentioned before regarding the diagram.
λέλεκται δὲ ὅτι τὸν προβληθέντα περιοδικῶν ἀριθμὸν ὡρῶν, ὃς ἐν τῷ μεταξὺ δυοῖν ἀρχῶν γίνεται παροξυσμὸς, ἐπισκέπτου πότερον μετρεῖ τὸν ἐν τῷ διαγράμματι περιεχόμενον ἀριθμὸν ὁντιναοῦν.
And it was said that you should examine whether the presented number of periodic hours, which is the paroxysm that occurs between two beginnings, measures any number contained in the diagram.
ἦσαν δ’ ἐκεῖνοι κατὰ πολλαπλασιασμὸν ὡρῶν εἰκοσιτεσσάρων γενόμενοι.
And those [numbers] had arisen according to the multiplication of twenty-four hours.
ἵνα οὖν χωρὶς διαγράμματος αὐτὸς εὑρίσκῃς ἐπὶ δακτύλου τοῦτο, ταυτὶ πρᾶττε.
Therefore, in order that you yourself may find this on your fingers without a diagram, do these things.
τοῦ μὲν ἓξ καὶ ὀκτὼ προβληθέντος, εὐκαίρως ἂν εὕροις τέσσαρας μὲν ἀμφημερινοὺς γιγνομένους, ὅταν ἓξ ὡρῶν προβεβλημένη περίοδος ᾖ· τρεῖς δ’, ὅταν ὀκτώ.
When six and eight are presented, you would easily find that four quotidian [fevers] arise when the presented period is of six hours, and three when it is of eight.
τοῦ δ’ ἑπτὰ προβληθέντος, ἤ τινος ἄλλου τῶν μὴ μετρούντων τὸν τῶν εἰκοσιτεσσάρων ὡρῶν ἀριθμὸν, ἐπισκέπτου πότερον ἔχει τι μέρος ὁ προβληθεὶς, ἢ οὐδὲν, ὅτι μὴ τὴν μονάδα.
But when seven is presented, or any other of those which do not measure the number of twenty-four hours, examine whether the presented [number] has any part (divisor), or none except for the unit.
εἰ μὲν ἔχει τι παρὰ τὴν μονάδα μέρος ἄλλο, καθάπερ ὁ μὲν ἐννέα τὸ τρίτον, ὁ δὲ πεντεκαίδεκα τὸ τρίτον τε καὶ τὸ πέμπτον, ἐπισκέπτου ποῖον αὐτοῦ τῶν μερῶν κοινόν ἐστι πρὸς τὸν τῶν εἰκοσιτεσσάρων.
If indeed it has some other part besides the unit—just as nine has a third, and fifteen a third and a fifth—examine which of its parts is common to that of twenty-four.
εὐθέως γοῦν τρίτον μὲν ὁ τῶν εἰκοσιτεσσάρων ὡρῶν ἀριθμὸς ἔχει, πέμπτον δ’ οὐκ ἔχει, καθάπερ ὁ τῶν πεντεκαίδεκα.
Immediately, at any rate, the number of twenty-four hours has a third, but it does not have a fifth, as that of fifteen [does].
ἐὰν μὲν οὖν προβεβλημένη περίοδος ὡρῶν ἐννέα τύχῃ, τὸ τρίτον μὲν ταύτης λήψῃ, τὸ τρίτον δὲ καὶ τῶν κδ΄ τὰ ὀκτὼ, καὶ φήσεις ὀκτὼ τύπους εἶναι τρισὶν ἡμέραις περιγραφομένους.
If, then, the presented period happens to be of nine hours, you will take the third of this, and the third of twenty-four, which is eight, and you will say that there are eight types circumscribed by three days.
ἠξίουν δέ σε μεμνῆσθαι τοὺς τοιούτους τύπους τεταρταίους ὀνομάζεσθαι.
And I requested you to remember that such types are called "quartans".
εἰ δὲ ιε΄ ὡρῶν περίοδος εἴη, τῶν μὲν ιε΄ τὸ τρίτον λαβὼν, πένθ’ ἡμερῶν εἶναι τοὺς τύπους, ὅπερ ἐστιν ἑκταίους· τῶν δὲ κδ΄ ἐπειδὴ καὶ τούτων τὸ τρίτον ὀκτὼ γίγνεται, τοσούτους ἐρεῖς εἶναι καὶ τοὺς ἑκταίους τύπους· εἰ δὲ μηδὲν μόριον ὁ προβεβλημένος ἀριθμὸς ᾖ, οἷός πέρ ἐστιν ὁ ζ΄, κδ΄ ὀγδοαίους.
And if the period is of fifteen hours, taking the third of fifteen, you will say that the types are of five days, which is "sextans"; and since the third of twenty-four is also eight, you will say that there are also this many sextan types; and if the presented number has no part [in common], just as seven is, there will be twenty-four "octans".
