Art

Art in the 9th century was primarily dedicated to the Gospel and employed as basic tools of liturgy of the Roman Orthodox Church. Thousands of golden art objects were made: Sacred cups, vessels, reliquaries, crucifixes, rosaries, altarpieces, and statues of the Virgin and Child or Saints all kept the flame of western art from dying out. Architecture began to revive to some extent in the West by the 9th century, taking the form of Church facilities of all kinds, and the first castle fortifications since Roman times began to take form in simple "moat and bailey" castles, or simple "strong point" tower structures, with little refinement.
