The question "this painting was created in which historical period?" is ambiguous without an image or description of the specific painting in question. Paintings can belong to various historical periods such as the Early period (cave paintings), Ancient civilizations, Renaissance, Baroque, Rococo, Romanticism, Modern art, or Contemporary art, each characterized by distinct styles and time frames. To provide an accurate answer, could the painting or its description be shared? Without that, only general information about painting historical periods can be provided.
