The myth of Sisyphus
This legendary sisyphus
Obliged to roll his stone
With courage and dignity
On the mountain top
A mythical ascent
Rolling his stone painfully
Such was his destiny
Never a victory
Like a night of Gethsemani
For all it’s life
A never ending tragedy

I think you need to specify somehow that the smallest circle is at the midpoint of the side of the larger triangle to which it is tangent.
