Where are they now?

بِسْمِ اللّهِ الرَّحْمـَنِ الرَّحِيمِ

Khayyam writes in one of his Rubaiyat:

آن قصر که با چرخ همیزد پهلو
بر درگه آن شهان نهادندی رو

دیدیم که بر کنگره‌اش فاخته‌ای
بنشسته همی گفت که کوکوکوکو

Roughly translated, it means:

That castle/palace which reached the sky

Towards whose door prostrated kings

All that remained on it's towers

A ringdove  singing repeatedly Koo Koo, Koo, Koo (where are they now)
