The name Antiphon the Sophist (/ ˈ æ n t ə ˌ f ɒ n,-ən /; Ancient Greek: Ἀντιφῶν) is used to refer to the writer of several Sophistic treatises. He probably lived in Athens in the last two decades of the 5th century BC, but almost nothing is known of his life.

Antiphon (Ancient Greek: Ἀντιφῶν) of Athens, according to the Suda, was an interpreter of signs, epic poet and sophist, surnamed Logomageiros (Λογομάγειρος), which means both "Word-cook" and "Word-butcher". None of his works are extant, and he is only attested in the Suda.
Antiphon was a statesman who took up rhetoric as a profession. He was active in political affairs in Athens, and, as a zealous supporter of the oligarchical party, was largely responsible for the establishment of the Four Hundred in 411 (see Theramenes); upon restoration of the democracy shortly afterwards, he was accused of treason and condemned to death.

Using available data, he obtains a velocity of 310 740 000 m/s and states "This velocity is so nearly that of light, that it seems we have strong reason to conclude that light itself (including radiant heat, and other radiations if any) is an electromagnetic disturbance in the form of waves propagated through the electromagnetic field according ...
[6] [7] Huygens reports on a letter by Ole Christensen Rømer, dated from 1677, where the speed of light is said to be at least 100,000 times faster than the speed of sound, and possibly six times higher. In the latter case, the speed found by Rømer (214,000 km /s) was of the same order of magnitude as the speed of light admitted today. [5]
The recent scholarly edition of Pendrick, however, sees it as probable that this treatise was written by the same author as the Sophistic works, as does the edition of Laks and Most. Some earlier scholars, though, including E. R. Dodds, take the view that Antiphon the dream-interpreter was a separate person. [1] [2]
For instance, the Fizeau wheel could measure the speed of light to perhaps 5% accuracy, which was quite inadequate for measuring directly a first-order 0.01% change in the speed of light. A number of physicists therefore attempted to make measurements of indirect first-order effects not of the speed of light itself, but of variations in the ...
