Giacomo Della Porta in the context of "Fontana del Pantheon"

Giacomo della Porta (1533–1602) was an Italian architect and sculptor. Most likely born in Genoa or Porlezza, Italy, his work was inspired by famous Renaissance artists such as Michelangelo and Giacomo Barozzi da Vignola. He started in his career as a sculptor in his late 20s, and later transitioned into a more architectural focus. Della Porta's work on the Oratory of Santissimo Crocifisso marked the beginning of his architectural career in Rome. In 1564, he was elected as Architetto del Popolo Romano (Architect of the Roman People) and under this title he completed some of his most notable commissions, both public and private. Throughout his career, Della Porta had a tendency to carry out projects begun by other architects, or make particular additions to a project of another architect, as opposed to completing a project of his own from start to finish.
