Beyond political and religious boundaries, unifying aspects can also be noted, such as a preference for allegorising and symbolic imagery, which is also expressed in the widespread emblem literature. In addition, there is a clear, depending on the "classicist degree", subdued or accentuated agitation in painting and graphic art as well as in sculpture and architecture. Curvatures, curves and diagonal compositions dynamise the two- and three-dimensional representations, while fundamentally maintaining realism. Another essential feature of High Baroque art is the tendency towards the Gesamtkunstwerk (total work of art) and the overcoming of genre boundaries between painting, sculpture and architecture. Illusionist wall and ceiling painting reached a high point in this context, and in Italy in particular, double and multiple talents such as Bernini and da Cortona left their mark on High Baroque art.
