Here is my code:

Note that if you want to wrap each set of coordinates with their own () like you have done in your query, you need to be using mysql 5.7.9+ the earlier versions do not support it. But that is not all, there is another error. mysql polygons have to be closed

SELECT ST_GEOMFROMTEXT('POLYGON((13.517837674890684 76.453857421875,13.838079936422464 77.750244140625,14.517837674890684 79.453857421875,13.517837674890684 76.453857421875,13.517837674890684 76.453857421875))')

And also note that (( and )) is the correct syntax
