An early story of the myth of Cephalus and Procris is told here (in German): Griechische mythologie by Ludwig Preller, 1809-1861; Carl Robert, 1850-1922, ed; Kern, Otto, b. 1863, ed. Published 1894. Here's a link:
In this version the Cephalus and Procris are hunting in the woods- but neither are aware that the other is hunting--Procris beats the bushes trying to scare game into the open and Cephalus throws his spear (javelin/dart) towards the noise and and kills her.
