^{page 46 note 6} Ibid, xxxvi. 67, 199, ‘vitrum sulphuri concoctum ferruminatur in lapidem’ means.: ‘when glass is heated with sulphur, it hardens into stone’(K. C. Bailey), not ‘makes a stone-hard joint’ (if, indeed, the true reading here is not nitrum). Further, in Pliny, Epp. viii. 20. 4: ‘sulphuris odor saporque medicatus (aquae), vis qua fracta solidantur’ (a passage which may have given rise to the belief mentioned in note 4 above), the solidifying function belongs to the water. The ‘sulphur’ there is merely a smell.

^{page 46 note 9} This would be particularly likely to happen with a glass which, in the fluid state, had a high surface-tension.

^{page 46 note 10} The meaning of abaculus(a diminutive form of abacus, occurring here only in Latin, if read), may be inferred by comparison with Greek ⋯βακ⋯σκος (a diminutive, form of βαξ‘slab’), which is found in Athenaeus, 5. 207 c, where Hiero's ship is described: τα⋯τα δ⋯ π⋯ντα δ⋯ντα δ⋯πεδονεἶχεν ⋯ν ⋯βακ⋯σκοις συγκε⋯μενον λ⋯θων, ⋯νοἶς κατεσκευασμ⋯νος π⋯ς ⋯ περ⋯ τ⋯ν Ἰλι⋯δα μ⋯θος θαυμασἰως, and in Eustathius x, p. 1927, 61 (on Homer, Od. xxii. 297): δ⋯λον δ' ⋯τι τ⋯ τοιο⋯τον βασιλικ⋯ν δ⋯πεδον κα⋯ κρατα⋯πεδον ἄν εἴη, δι⋯ τ⋯ ὡς. We may conclude that άβακ⋯σκος was a technical term for a small stone used in the making of mosaics, and similarly that abaculus was a Latin technical term, meaning a small pellet used in mosaics. In the present case it would be of glass.

^{page 46 note 5} Compare the amusing epitaph on a musivarius (in Dessau, Inscr. Sel. 7671), who fell off his ladder and was killed: ‘hic sit(us)…prima iuventa fuit: dum varias cupit spec(ies) museo figere in alto decidit.’

^{page 46 note 6} The source of sulphur nearest to Rome was in the Leucogaean Hills, near Naples, about 130 miles south of the city (Pliny, , H.N. xviii. 297, 114, xxxv.50, 174Google Scholar). If the huckster went on an expedition to dig it up for himself, transtiberinus ambulator (Mart. i. 41. 3) may have a double meaning, and thus gain added significance!
