CA|other uses of "Cca"|CCA (disambiguation)|CCA|other uses of "Circa"|Circa (disambiguation)}}Template:TWCleanup2Circa (from la 'around, about, roughly, approximately') – frequently abbreviated ca. or c. and less frequently circ., cca. or cc. – signifies "approximately" in several European languages and is used as a loanword in English, usually in reference to a date.[1] Circa is widely used in historical writing when the dates of events are not accurately known.
When used in date ranges, circa is applied before each approximate date, while dates without circa immediately preceding them are generally assumed to be known with certainty.

BC) was a Macedonian astronomer best known for designing the Tower of the Winds in Roman Athens.
Life
Little is known about the life of Andronicus, although his father is recorded as Hermias. It is usually assumed that he came from the Cyrrhus in Macedonia rather than the one in Syria.[1]
Work
Andronicus is usually credited with the construction of the Tower of the Winds in the Roman forum at Athens around 50 BC, a considerable portion of which still exists.[2] It is octagonal, with figures of the eight principal winds (Anemoi) carved on the appropriate side.[3] Originally, a bronze figure of Triton was placed on the summit that was turned round by the wind so that the rod in his hand pointed to the correct wind direction, an idea replicated with subsequent wind vanes.[4] The interior housed a large clepsydra and there were multiple sundials on the exterior, so that it functioned as a kind of early clocktower.
He also built a multifaced sundial for the Temple of Poseidon on the island of Tinos.
