Luke 7:15 wrote:Καὶ ἀνεκάθισεν ὁ νεκρός, καὶ ἤρξατο λαλεῖν. Καὶ ἔδωκεν αὐτὸν τῇ μητρὶ αὐτοῦ.
are both in "medical" circumstances, rather than as part of the daily routine.Acts 9:40 wrote:Ἐκβαλὼν δὲ ἔξω πάντας ὁ Πέτρος θεὶς τὰ γόνατα προσηύξατο· καὶ ἐπιστρέψας πρὸς τὸ σῶμα, εἶπεν, Ταβηθά, ἀνάστηθι. Ἡ δὲ ἤνοιξεν τοὺς ὀφθαλμοὺς αὐτῆς· καὶ ἰδοῦσα τὸν Πέτρον, ἀνεκάθισεν.
A few other quotes are
Which is clearly a medical context, but not descriptive of the action at all.Hippocrates, Prognosticon, 3 wrote:Ἀνακαθίζειν δὲ βούλεσθαι τὸν νοσέοντα, τῆς νούσου ἀκμαζούσης, πονηρὸν μὲν ἐν πᾶσι τοῖσιν ὀξέσι νουσήμασι, κάκιστον δὲ ἐν τοῖσι περιπλευμονικοῖσιν.
The imagery that Cadbury introduces here from Hierocles is about a horse which is unable to stand up, but which props up it body using its forelegs like a dog.Hierocles, 181, 17 wrote:Ἀναπεσὼν δὲ ἐγείρεσθαι πάλιν τοῖς ὀπισθίοις ἀδυνατεῖ ἀλλ ἀνακαθίζει ὡς κύων τοῖς ἐμπροσθίοις
The usual way that rabbits sit (up) is propped up on the forelegs, rather than than on just the hindlegs, which they will do for a moment to reach up to something.Xenophon, On Hunting 5.7 wrote:ἐν δὲ τοῖς ὑλώδεσι μᾶλλον ἢ ἐν τοῖς ψιλοῖς ὄζει: διατρέχων γὰρ καὶ ἀνακαθίζων ἅπτεται πολλῶ.
Evidently this image is of Socrates not leaning his weight on the couch, which ἀνακλίνω might suggest, but sitting up himself, and with one or both of his legs up in the air or bent up close to him, it is probable that the arm that was not rubbing the leg, was propping him up.Plato, Phaedo wrote:[60b] τε καὶ κοπτομένην: ὁ δὲ Σωκράτης ἀνακαθιζόμενος εἰς τὴν κλίνην συνέκαμψέ τε τὸ σκέλος καὶ ἐξέτριψε τῇ χειρί, καὶ τρίβων ἅμα, ὡς ἄτοπον, ἔφη, ὦ ἄνδρες, ...
My take on that is that this is a word used to describe a type of sitting propped up or steadied by the arms, or that the arms are used to push or walk the body up to a seated position, rather than by swinging the legs over the side of the bed etc. to role then balance the torso in a seated position, in our literature on somebody sitting up on a bier or on a bed after sickness.
What circumstances could that be used in composition for?
