Borromini’s San Carlo and the Bernini’s David are both demonstrative of Baroque form. One key factor is the way in which both pieces harken back to classicism in their design. That said this is distinguishable from that of the Renaissance (which also mirrored classical form) through the prevalence of greater ornamentation and ovate geometry in the case of San Carlo or the depiction of the realistic over idealized human form in the David. Most distinctively both display the trademark Baroque rhythm through which aspects of the proportions and construction play off one another to form a more dynamic whole.
