conflux

A merger of rivers, or the place where rivers merge.

It stands on the conflux of two rivers—the Chelmer, whence the town is called, and the Cann.

A convergence or moving gathering of forces, people, or things.

Thence to the gates caſt round thine eye, and ſee / What conflux iſſuing forth, or entring in: / Pretors, Proconſuls to thir Provinces / Haſting or on return, in robes of State; / Lictors and rods the enſigns of thir power; / Legions and Cohorts, turmes of horſe and wings: […]

There was a conflux of emotions and thoughts in him that would not let him either give thorough way to his anger or persevere with simple rigidity of resolve.
