My purpose here is to point out a use of the Greek word κλῖμαξ, lit. ladder, which has not been recorded in the lexica of ancient and medieval Greek.Footnote 1 To be specific, the term is found twice in the Therapeutics, a work by the sixth-century a.d. author and practising physician Alexander of Tralles, in reference to a particular kind of composite drug.Footnote 2 In the first case, the author refers to the so-called ‘ladder of Hermes’ (Ἑρμοῦ κλῖμαξ, Ther. 1.557.6) without providing any recipe.Footnote 3 According to him, this is an antidote for the treatment of epilepsy and similar in action to the well-known theriac.Footnote 4 However, in the second case referring to an antidote for the treatment of gout, the ‘so-called ladder’,Footnote 5 he provides the following recipe (Ther. 2.571.16–26):

As evidenced, the term denotes a unique category of composite drugs in which the quantity of each subsequent ingredient is increased by one unit (1 ounce, 2 ounces, 3 ounces and so on), thus metaphorically alluding to an ascending scale.
