464 रत्नावली
or the second day after the Full-moon day. It could not take
place on the Full-moon day, as from the description of the
deep darkness setting in, it is quite evident that the moon
was of the dark fortnight. The scene of Act III proper is
laid towards the latter part of the afternoon when the King
became anxious to be present in the place of assignation
where Ságariká would come in the disguise of the Queen.
The whole of Act III continued after the moon-rise of that
evening and the Act closes when Ságariká being detected by
Vāsavadattá in the place of assignation was taken captive
along with the Vidusaka and was removed, as told by
Susangatá in the interlude before Act IV, to some unknown
destination in the midnight ( उबत्थिदे षद्धरत्ते ).
The action in Act IV is expected to have taken place on
the very next day after Act III. On that date the magician
came and thorough his wonderful feat the union of the hero
with the heroine was brought about.
Thus the action of the four Acts has been represented as
having taken place roughly within the period of four days
extending from the fourteenth day of the bright fortnight
to the second ( or third ) day of the dark half of the month of
Chaitra.
So the three unities, as enjoined by the authoritative
works on Sanskrit dramaturgy, have been strictly maintained
in the Drama.
