Aulus Umbricis Scaurus was a Pompeiian manufacturer-merchant, known for the production of garum and liquamen (types of fermented fish sauce), a staple of Roman cuisine. He was active in Pompeii between c. 25-35 CE and 79 CE. Scholars believe that A. Umbricius Scaurus was Pompeii's leading fish sauce manufacturer. His products were traded across the Mediterranean in the first century.
