Ancient sex toy?

Just kidding. It's the Cone of Entemena (song to the tune of "Girl from Ipanema").

 

The translated inscription reads:

 

For (the goddess) Inanna,

(and for) the Divine King of the Emus,

Entemena,

Governor of Lagash,

the Emus

their beloved Temple,

(he) built.

They (also) commanded him (to produce

and implant) cones (in the Temple wall).

Entemena,

The man who built the Emus,

his (personal) deity is

Sul-utula.

At that time, Entemena,

the Governor of Lagash,

(and) Lugal-kinesdu,

the Governor of Uruk,

"made brotherhood."

(i.e. made an agreement or alliance)
