"O little mother of ancient days"

Sa’dee Al-Shirazee wrote in his "Gulistan":

پيرزنى موى شيرى سيه كرده بود گفتم اى مامك ديرينه روز موى به تلبيس سيه
كرده گير راست نخواهد شد اين پشت كوز

ENGLISH:

"An old hag had dyed her hair black.
I said to her: "O little mother of ancient days,
Thou hast cunningly dyed thy hair but consider
That thy bent back will never be straight".

["Gulistane Sa'dee", 227].
