The image is a photograph of a plaque on a wall that reads "323 B.C. After the death of Alexander, his empire is divided into four parts." The plaque is white with black text and is mounted on a beige wall. The text is written in a serif font and is centered on the plaque. Below the text, there is a subtitle that explains that one of Alexander's former generals, Seleucus I, gained control of Iran, Mesopotamia, northern Syria, and the greater part of Anatolia (Turkey). The Seleeucus founded many new cities, which they designed according to the Greek grid plan. Their two capitals were Selecucus-on-the-Tigris, which is a type of ancient Greek civilization. The plaque also mentions that the ancient civilization was established in the early 20th century.
