‘I know the wealth of every urn

In which unnumbered rubies burn,

Beneath the pillars of Chilminar;

I know where the isles of perfume are,

Many a fathom down in the sea,

To the south of sun-bright Araby;

I know too, where the Genii hid

The jewelled cup of their King Jamshid,

With life’s elixir sparkling high.’

Lalla Rookh.
