These are a couple of example of Cledonomancy in Homer's "Odyssey." Cledonomancy is also a branch of Augrey.
As she spoke Telemachus sneezed so loudly that the whole house
resounded with it. Penelope laughed when she heard this, and
said to Eumaeus, Go and call the stranger; did you not hear
how my son sneezed just as I was speaking? This can only mean
that all the suitors are going to be killed, and that not one
of them shall escape. Furthermore I say, and lay my saying
to your heart: if I am satisfied that the stranger is speaking
the truth I shall give him a shirt and cloak of good wear.
~~ The Odyssey Book XVII
On this the day broke, but Ulysses heard the sound of her weeping,
and it puzzled him, for it seemed as though she already knew him
and was by his side. Then he gathered up the cloak and the fleeces
on which he had lain, and set them on a seat in the cloister, but
he took the bullock's hide out into the open. He lifted up his hands
to heaven, and prayed, saying "Father Jove, since you have seen
fit to bring me over land and sea to my own home after all the
afflictions you have laid upon me, give me a sign out of the mouth
of some one or other of those who are now waking within the house,
and let me have another sign of some kind from outside."
Thus did he pray. Jove heard his prayer and forthwith thundered
high up among []the splendour of Olympus, and Ulysses was glad
when he heard it. At the same time within the house, a miller-woman
from hard by in the mill room lifted up her voice and gave him
another sign. There were twelve miller-women whose business it
was to grind wheat and barley which are the staff of life. The
others had ground their task and had gone to take their rest,
but this one had not yet finished, for she was not so strong as
they were, and when she heard the thunder she stopped grinding
and gave the sign to her master. "Father Jove," said she, "you
who rule over heaven and earth, you have thundered from a clear
sky without so much as a cloud in it, and this means something
for somebody; grant the prayer, then, of me your poor servant
who calls upon you, and let this be the very last day that the
suitors dine in the house of Ulysses. They have worn me out with
the labour of grinding meal for them, and I hope they may never
have another dinner anywhere at all."Ulysses was glad when he heard
the omens conveyed to him by the woman's speech, and by the
thunder, for he knew they meant that he should avenge himself on
the suitors.
~~ The Odyssey Book XX
Meanwhile the suitors were hatching a plot to murder Telemachus:
but a bird flew near them on their left hand- an eagle with a
dove in its talons. On this Amphinomus said, "My friends, this
plot of ours to murder Telemachus will not succeed; let us go
to dinner instead."
