Who was the architect of the Dionysus theater?

The Theater of Dionysus in Athens, which is considered one of the earliest and most important theaters in ancient Greece, was primarily associated with the architect Philoctetes. However, it underwent several renovations and modifications over time, particularly during the 4th century BCE under the influence of other architects like Lysikrates. This theater served as a key venue for the presentation of tragedies and comedies in honor of the god Dionysus.
