lu'-shi-us, lu'-shus (Loukios, Leukios): A Roman consul who is said (1 Macc 15:16 ff) to have written a letter to Ptolemy Euergetes securing to Simon the high priest and to the Jews the protection of Rome. As the praenomen only of the consul is given, there has been much discussion as to the person intended. The weight of probability has been assigned to Lucius Calpurnius Piso, who was one of the consuls in 139-138 BC, the fact of his praenomen being Cneius and not Lucius being explained by an error in transcription and the fragmentary character of the documents. The authority of the Romans not being as yet thoroughly established in Asia, they were naturally anxious to form alliances with the kings of Egypt and with the Jews to keep Syria in check. The imperfections that are generally admitted in the transcription of the Roman letter are not such as in any serious degree to invalidate the authority of the narrative in 1 Maccabees.
