Examples

“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 Janus. Domestic war now rendered the admonition superfluous, and the ceremony was superseded by the establishment of a new religion. But the brazen temple of Janus 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.”
“[K]nowing that the minds of the people, rendered ferocious by a military life, would never accommodate themſelves to the practice of theſe [principles of justice, laws, and morals], during the continuance of war, he [Numa Pompilius] reſolved, by a diſuſe of arms, to mollify the fierceneſs of their temper: with this view, he built a temple to Janus, near the foot of the hill Argiletum, which was to notify a ſtate either of war or of peace: when open, it denoted that the ſtate was engaged in war; when ſhut, that there was peace with all the ſurrounding nations.”
“"I'll tell you what we can do," cried her persevering patroness; "we can go as masks, and Lady Juliana shall know nothing about it. That will save the scandal of an open revolt or a tiresome dispute. Half the company will be masked; so, if you keep your own secret, nobody will find it out. Come, what characters shall we choose?" / "That of Janus, I think, would be the most suitable for me," said Mary.”
“We find ourselves once again sitting in Committee of the Whole House to vote a war subsidy. The present occupants of the Treasury Bench are determined that so long as they retain their places the Temple of Janus shall not be closed.”
“Janus, with his two heads, his mystery, his depiction as both laughing and serious, and the obvious parallel this forms with the masks of attic tragedy and comedy would make him a double of the two-headed man, the conjurer, and an associate of the trickster in folk comedy as well.”
“Good reviews look both backward and forward; an argument could even be made that one must look backward in order to discern the way forward, that backward and forward are two sides of the same research coin. Nowhere is such a Janus-like perspective more apparent than in the current set of reviews.”
“Janus cat, Janus particle”
“But other categories of word-play have not been researched extensively or systematically. Among the latter is the type of word-play known as polysemous parallelism, or more commonly, Janus parallelism. The latter term was coined by Cyrus Gordon to describe a literary device in which a middle stich of poetry parallels in a polysemous manner both the line that precedes it and the line which follows it.”
“The novel seems to be rather autobiographical, but in retrospect one can see about three-quarters through the text there is a turn from an autobiographical into a future novel[…]. De chauffeur verveelt zich is a real Janus-novel, looking into two directions.”
“The ability to look at both sides of a coin before giving a verdict can be both a curse and a blessing. […] This "Janus effect" (my term) is a curse when it blocks a time sensitive judgment response, or a decision waiting to be made before long. […] Friendships, sibling harmony, good relationship with associates at work, and especially marriages, could be great and positive recipients of the good that such a Janus effect could bring on.”
“A Janus fluid is one made of Janus particles immersed in a solvent. A Janus particle like the Roman God Janus, […] is one that has two faces with two different functionalities.”
“Janus green B is a dye used widely in histology to stain cells for microscopic examination.”
“In order to show that such stains are due to oxycellulose, the fabric should be stripped with titanous chloride solution or sodium hydrosulphite. On redyeing with Janus Blue the oxycellulose patches are more heavily dyed. The writer prefers Janus Blue to the Methylene Blue which is usually recommended.”
“Janus Dyes. Named after the God, Janus with two faces since they often exhibit two colors.”
“The significance of the molecular shape of the dyes in induction of the birefringence of polyanions is illustrated with topo-optical reactions of the Janus dyes. Janus red, yellow, green, black, and blue are cationic azo dyes[…]. All of these exhibit a moderate metachromatic effect with sulfated GAGs [glycosaminoglycans].”
“In 1900, L[eonor] Michaelis (who later became famous for his studies of enzyme kinetics) found that mitochondria in living cells could be specifically stained by the dye Janus Green B[…]. Because this dye must be oxidized to become colored, Michaelis proposed that mitochondria are cellular oxidizing agents.”
“The hypocrite; or, The modern Janus.”
“Heavily cratered and irregularly shaped, Janus orbits Saturn just beyond the F ring and only 50km (30 miles) farther away than its co-orbital moon, Epimetheus.”
“Two of Saturn's small moons have the unique distinction of sharing the same orbit. Epimetheus and Janus circle the Lord of the Rings at a distance of just over 151,000 km, about half the distance from Earth to the Moon. Both are irregularly shaped. Janus is 179 km across, while Epimetheus is about 116 km in diameter.”
