The authorship of the painting is attributed to an unknown Italian artist of the first half of the 17th century. It depicts two half-figures: the ruler on the right and another person on the left. Behind them is a raised theatre curtain. This stylistic technique, which transformed the scene into a theatrical performance, was common among Roman artists in the first half of the 17th century. This fact may indicate the artist's association with the Roman school. The painting was most likely executed between 1620 and 1650 when half-figure scenes were popular among Italian collectors. However, it is difficult to confirm that the person portrayed is Alexander the Great, as the presented plot differs from the cycle of his life scenes.
