The biographical tradition reports that Plautus was born Macc(i)us, an Umbrian from Sarsina (in northern Italy) and acquired the cognomen Plotus/Plautus for his flat feet. On coming to Rome, he worked as a stagehand, and possibly as an actor. He left Rome on a business venture and when that failed, worked for a miller after returning. All these details are suspect.

His play are trationally edited in alphabetical order, as follows:

Some 130 plays circulated under Plautus' name in antiquity. According to Varro in the first century BC, the above 21 plays were generally considered authentic, but opinions varied on others. A handful of fragments from at least 32 different plays (not counting the canonical 21) survive. Lack of testimony and frequent revivals of Plautus' plays make dating any plays hazardous.

Below are a number of standard scholarly books about Roman Comedy, especially about Plautus.  The linked web pages provide an outlined summary of the book and guides to further information.
