Final answer:
It is false that side A of the Attic black figure panel amphora features the tethrippon; instead, it depicts Ajax and Achilles playing a game.
Step-by-step explanation:
The statement that side A of the Attic black figure panel amphora features a depiction of the tethrippon, a four-horse chariot race, is False. The Attic black-figure amphora known for depicting Ajax and Achilles playing a game was crafted by Exekias around 540-530 BCE. This amphora does not show a tethrippon, but instead illustrates these two warriors engaged in a game during a moment of relaxation between battles, which is indicated by their attire and the setting around them.
The detailed imagery described on the Dipylon Amphora also does not correspond to the tethrippon, as it depicts a funerary procession with soldiers and uniquely shaped shields. Additionally, the griffin-drawn chariot and other art pieces mentioned do not represent a chariot race.
