Note 39 — Chapter XVIII · AN ACCOUNT OF PITRIS.
Manmatha Nath Dutt translation
This refers to Veda Vyasa who compiled and arranged the four Vedas. The word Vyasa means "an arranger" Veda Vyasa is the surname of a Rishi, the son of Parashara, who compiled the four Vedas. The Vedas originally existed in the shape of hymns that were sung by the ancient Aryans and passed from one family to another as sacred heir-looms. For some centuries they existed in this form. It was this great Rishi who first committed them to writing and arranged them in the order in which they are now found. The four divisions are his own creation. On account of this great work he received the appellation 'Veda-Vyasa'.
