These people believed our way of life was superior to the way of living in other countries. Another reason why we pursued a policy of imperialism was because we wanted to be viewed as a world power. ... We didn't have these colonies and felt we needed them to be viewed as a strong country.
The most detailed Roman mosaics use small stones to achieve an effect like brushstrokes. Especially in the eastern provinces of the Roman empire, artists “painted” with stone. Hope this helped :)
