glutine mediante, induxcrunt, defuperque 

 appliclto gypib, poftmodo demum pi6buras 

 Rias .cffigurarunt, qui modus dici folet alia 

 tempera, id eflj temperaturae aquariae. Hanc 

 autem temperaturam ita praeparabant : ef- 

 fra6lo prius ovo gallinaceo, in ejufdem li- 

 quore frondem teneram ficulneam de ficu 

 iuniore difcutiebant : ubi e ladle iftius fron- 

 disj eque vltello ilia nafcebatur tempcra- 

 tura : qua mediante, poftmodum loco aquae 

 vel gummi, vel tragacanthae, colores fuos

When they painted on walls, left their 

 work fhould crack, they proceeded in this 

 manner : They glued a linnen cloth upon 

 the wall, and covered that with plaifter, on 

 which they painted in diftemper : This was 

 thus prepared : They dropped into the 

 yolk of an egg the milk that flows from the 

 leaf of a young fig-tree, with which inftead 

 of water, gum, or gumdragant, they mixed 

 their laft layer of colours. It is probable 

 from the laft words of this paftage that they 

 kid their firft colour with water or gum only.
