Note 122 — BOOK XXIV. THE REMEDIES DERIVED FROM THE FOREST TREES.
John Bostock translation
See B. xvi. c. 23. His description here is faulty, it being solely a natural pitch or mineral bitumen, without any admixture of vegetable pitch. Vitruvius calls this pissasphalt, pitch; but Ælian, more correctly, bitumen. The names now given to it are mineral pitch, and malthe or pitch of Malta.
