The author or compiler of the "Thucydides Commentary" is anonymous. The work dates from the Late Antique period, an era of significant scholarly activity focused on explicating classical texts. As a grammatical commentary, it was likely produced by a scholar within the educational centers of Alexandria, Athens, or Constantinople, engaged in standard philological and exegetical work to aid students.

The sole known work is the Thucydides Commentary, an exegetical text on Thucydides' History of the Peloponnesian War. It represents one strand of a complex commentary tradition, drawing from earlier scholars like Didymus Chalcenterus and Aelius Herodianus. The work is preserved fragmentarily within the later medieval scholia on Thucydides.

This commentary is part of the essential late antique effort to interpret and transmit Thucydides' challenging history. It served key pedagogical and preservative functions, explaining historical references, language, and style, thereby ensuring Thucydides' survival as a model of Attic prose and a vital historical source through subsequent centuries.
