Meridian Lines
A horizontal line aligned on a meridian with a gnomon facing the noon-sun is termed a meridian line and does not indicate the time, but instead the day of the year. Historically they were used to accurately determine the length of the solar year. Examples are the Bianchini meridian line in Santa Maria degli Angeli e dei Martiri in Rome, and the Cassini line in San Petronio Basilica at Bologna.

Famous quotes containing the words meridian and/or lines:
“I knew that my vocation was found. I had received the call, and having done so, I was sure my work would be assigned me. Of some things we feel quite certain. Inside there is a click, a kind of bell that strikes, when the hands of our destiny meet at the meridian hour.”
—Amelia E. Barr (1831–1919)
“There is something to be said for government by a great aristocracy which has furnished leaders to the nation in peace and war for generations; even a Democrat like myself must admit this. But there is absolutely nothing to be said for government by a plutocracy, for government by men very powerful in certain lines and gifted with the “money touch,” but with ideals which in their essence are merely those of so many glorified pawnbrokers.”
—Theodore Roosevelt (1858–1919)
