In reference to the verse in Yechezkel (18:4) which states "and the women sat, weeping over the Tammuz" - many commentaries try to explain who the Tammuz was. Amongst the opinions brought, and perhaps the most detailed, is that of the Rambam (Moreh Nevuchim 3:29).
Here is a translation of the Rambam- "One of the idolatrous prophets, named Tammuz, called upon the king to worship the seven planets and the twelve constellations of the Zodiac: whereupon the king killed him in a dreadful manner [מיתה משונה]. The night of his death the images from all parts of the land came together in the temple of Babylon which was devoted to the image of the Sun, the great golden image. This image, which was suspended between heaven and earth, came down into the midst of the temple, and surrounded by all other images commenced to mourn for Tammuz, and to relate what had befallen him. All other images cried and mourned the whole night; at dawn they flew away and returned to their temples in every corner of the earth. Hence the regular custom arose for the women to weep, lament, mourn, and cry for Tammuz on the first day of the month of Tammuz."
Does anyone actually speak of how the Tammuz died?
