In ancient Greek tradition, what riddles did have the Sphinx in her "repertoire", besides the famous:
Which creature goes on four feet in the morning, two feet at noon, and three feet in the evening?
Wikipedia also mentions this one:
There are two sisters: one gives birth to the other and she, in turn, gives birth to the first. Who are the two sisters?
Of course, with one "killer" riddle, the Sphinx would have had enough but, quoting Wikipedia again (emphasis mine):
Michael Maier in his book, the Atalanta Fugiens (1617) writes the following remark about the Sphinx's riddle:
Sphinx is indeed reported to have had many Riddles, but this offered to Oedipus was the chief, "What is that which in the morning goeth upon four feet; upon two feet in the afternoon; and in the Evening upon three?"
I'm curious if tradition or ancient authors assign her any other riddles besides those two quoted above.
