What is Sundial?
[[File:Saint-remy-de-provence-cadran-solaire.jpg|thumb|A sundial]] [[File:Cornell_Plantations_sundial.jpg|thumb|A garden sundial at 9:30am]] A '''sundial''' shows the current [[solar time]] during the day. It does this because the [[sun]] appears to move through the sky. At different times in the day when the sun is shining, a [[shadow]] is cast in different places on the dial. A person marks the dial with the time at a certain shadow. This lets users easily see the time. There are a few commonly seen designs, such as the 'ordinary' or standard horizontal garden sundial. However, sundials can be designed for any surface where a fixed object casts a predictable shadow. They may be horizontal or vertical or tilted. Ancient [[Egypt]] had sundials. Other [[culture]]s developed them further, including the [[Ancient Greece|Greeks]] and [[ancient Rome|Romans]]. ==Related pages== * [[Time]] * [[Water clock]] * [[Clock]] == Other websites == {{sisterlinks|sundial}} * [http://www.liverpoolmuseums.org.uk/nof/sun/ Sunbeams and Sundials] Children's guide to the sun, the seasons and sundials. * [http://www.wdl.org/en/item/2841 There is a book from 1319 that talks about sundails] * [http://www.wdl.org/en/item/4260 There is another old book from the 1500's that talks about how to make a sundial.] It's written in the [[Arabic language]] [[Category:Clocks]]
