“In immense silence, 
They measure themselves awhile; 
Each suddenly throws himself upon the other; 
Transported, gripped alike, 
Their threatening arms do bend, 
Pressed flank to flank; 
Like a great, uprooting oak, 
Their trunk leans o’er and sways 
Above their entangled knees.”

Delacroix was maybe inspired by Lamartine’s ‘Poetical Meditations’ which describe the two beings entwined like the knotted trunks of the trees looming over them.
