From a single Lucca codex, a lost voice of Roman know-how speaks again. A workshop manual in Latin. John M. Burnam's A classical technology, edited from the Codex Lucensis, 490, is an annotated scholarly edition that brings late antique Latin technical writing into clear view. Built as a critical text edition with careful latin manuscript transcription, it lets readers follow the craft of transmission as much as the craft described: the practical language of tools, processes, and materials, preserved in a medieval book from Lucca, Italy. For anyone drawn to ancient technology history, classical engineering techniques, or roman science and crafts, it offers rare access to the vocabulary and mindset behind making, measuring, and building. More than a curiosity, this manuscript studies sourcebook is a solid classics research reference and a useful vitruvius studies companion, setting lesser-known ancient engineering primary sources alongside the broader tradition of technical prose. It sits at the crossroads of philology and practice, where a turn of phrase can change the shape of a mechanism. Readers focused on manuscript studies will appreciate how the Lucca Italy codex anchors interpretation, in workshops and schools alike. Scholars will value the editorial judgement and notes; curious readers will relish the directness and ingenuity of the surviving tradition. A direct route to antiquity, for study desks, shared libraries, and private collections. Out of print for decades and now republished by Alpha Editions. Restored for today's and future generations. More than a reprint -- a collector's item and a cultural treasure.
