and some other hold opinion, that he went thither with Hercules against
the Amazons, and that to honour his valiantness, Hercules gave him
Antiopa the Amazon. But the more part of the other Historiographers ...
do write, that Theseus went thither alone, after Hercules' voyage, and
that he took this Amazon prisoner, which is likeliest to be true."

At this point we should interpolate the reason why Hercules went against
the Amazons. The ninth (as usually enumerated) of the twelve labours of
Hercules was to fetch away the girdle of the queen of the Amazons, a gift
from her father Ares, the god of fighting. Admete, the daughter of
Eurystheus (at whose bidding the twelve labours were performed) desired
this girdle, and Hercules was sent by her father to carry it off by force.
The queen of the Amazons was Hippolyta, and she had a sister named Antiopa.
One story says that Hercules slew Hippolyta; another that Hippolyta was
enticed on board his ship by Theseus; a third, as we have seen, that
Theseus married Antiopa. It is not easy to choose incidents from these
conflicting accounts so as to make a reasonable sequence; but, as North
says, "we are not to marvel, if the history of things so ancient, be found
so diversely written." Shakespeare simply states that Theseus "woo'd"
Hippolyta "with his sword." Later in the play we learn that the fairy King
and Queen not only are acquainted with court-scandal, but are each involved
with the past histories of Theseus and Hippolyta (II. i. 70-80).

Apart from these incidents in Theseus' life, Chaucer supplies the dramatist
with all he requires in the opening of _The Knightes Tale_, which we shall
discuss in full shortly.[1]
