The first was subsequently known as Mithradatum Damocrates, and the second as Theriaca Andromachi, the name Theriaca or Tiriaca being derived from the snake called Tyrus, the flesh of which was added to it by Andromachus.
The apothecaries' ordinance at Nuremberg provided that no Theriaca should in future be branded with the seal of the city unless it had been previously examined and declared worthy of the same by the doctors of medicine, and that every druggist must know the age of the Theriaca he sold.
The last public preparation of Theriaca took place at Nuremberg in 1754.
The longest, Theriaca, is an hexameter poem (958 lines) on the nature of venomous animals and the wounds which they inflict.
The Theriaca prepared at Venice had the highest reputation, probably because in Venice the component parts were exposed to the inspection of wise men and doctors for two months, to determine whether they were or were not fit for use.
