Did early string quartets used a basso continuo to supply harmonies?

Early string quartets did not typically use a basso continuo. Instead, they were composed for four independent instruments—two violins, a viola, and a cello—each contributing to the harmony and counterpoint. The harmonic structure was often implied through the interplay of these voices rather than relying on a keyboard or other instrument to provide a continuous bass line. This approach marked a significant shift towards a more polyphonic texture in chamber music.
