These other documents include ancient creedal statements (the Nicene Creed, the Apostles' Creed), 16th-century Reformed confessions (the Scots Confession, the Heidelberg Catechism, the Second Helvetic Confession), and 20th century documents (The Theological Declaration of Barmen, Confession of 1967 and A Brief Statement of Faith).

Greek art has a long and varied history. Greeks have contributed to the visual, literary and performing arts. In the West, ancient Greek art was influential in shaping the Roman and later the modern western artistic heritage. Following the Renaissance in Europe, the humanist aesthetic and the high technical standards of Greek art inspired generations of European artists. Well into the 19th century, the classical tradition derived from Greece played an important role in the art of the western world. In the East, Alexander the Great's conquests initiated several centuries of exchange between Greek, Central Asian and Indian cultures, resulting in Greco-Buddhist art, whose influence reached as far as Japan.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What input did the Greeks have on artistry of the world ?
Ah, so.. visual, literary and performing arts.
