Translation:
Ferugo, scoria of iron and cacaferri {"slag of iron"} are the same, and it is the matter that ironsmiths remove in lumps from their furnaces.
Commentary:
Simon uses a number of words, ferrugo "iron rust", scoria – of Greek origin - "dross, slag, scoria of metals", and cacaferri. This last word is mentioned by Du Cange with a quote from Matthaeus Silvaticus, which is in part identical: CACAFERRI: Scoria ferri, i. squamma ferri, quam fabri ferrarii de fornacibus ejiciunt globatim, Lat. ærugo ferri, dicitur etiam Cacaferri. It literally means "excrement if iron" and is reminiscent of the expression used in Dioscorides Longobardus, 5, 105, De merda ferri "on excrement of iron". Merda "excrement" is probably an attempt to render the word scoria, which is itself derived from σκῶρ /skôr/ meaning "dung, ordure".
In Wellmann's edition this text is only a part of a longer chapter on iron slag, cf. 5, 80, (1906-14: III.52): ἰὸς σιδήρου /iòs sidḗrou/ {"iron rust"}.
