Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE ASTRONOMER AND THE THRACIAN WOMAN
When Thales the astronomer was gazing up at the sky, he fell into a pit. A Thracian
slave woman, who was both wise and witty, is said to have made fun of him for
being eager to know what was happening over his head while failing to notice
what was right there at his feet.

You can find a compilation of Perry's index to the Aesopica in the gigantic appendix to his
edition of Babrius and Phaedrus for the Loeb Classical Library
(Harvard University Press: Cambridge, 1965). This book is an absolute must for anyone interested
in the Aesopic fable tradition. Invaluable.
