Sentence:  In the ages of victory, as often as the senate decreed some distant conquest, the consul denounced hostilities, by unbarring, in solemn pomp, the gates of the temple of <WSD>Janus</WSD>. Domestic war now rendered the admonition superfluous, and the ceremony was superseded by the establishment of a new religion. But the brazen temple of <WSD>Janus</WSD> was left standing in the forum; of a size sufficient only to contain the statue of the god, five cubits in height, of a human form, but with two faces, directed to the east and west. 
Meaning of the word marked with <WSD> tags:  The god of doorways, gates and transitions, and of beginnings and endings, having two faces looking in opposite directions.
