The present writer was at first of the opinion that such pieces were at least partially en-graved by rotary his observa-tions mainly on a ring-bezel in the collections of the Victoria and Albert :\.1uscum (Fig. 1). This came from the 1904-05 excavations at Deir cl Bahri and is engraved with of the prenomen of Rameses. 6 On :first examination this piece seemed to show in
the "characteristic ends of wheel cuts/' it was evident that much of the work had been done with a point. Further investigation, however, combined with an examination of a dozen or so pieces of
of the 19th to 22nd in the British 1vlusemn col1ection, has convinced him that these were pmbably wholly point-engraved. The only certain traces of ro-
work on these of glass, and on one or two carneHan consisted of circular which had in some instances been used as the basis of hiemglyphs or other motivcs. 7 That this fact is not without

pressure to the head of his spindle, and it has been that he is in fact drilling the beads held at the other end of the apparatus. 31
A machine of this sort~ however1 would require very little adaptation to turn it into an engrav-
That gems were being wheelcut at this date is indicated by Antonio Averlino Filarctc's treatise Trattato delT Architettum, which was finished in 1464. Among the misce1Janeous information surveyed in his hook, Filarete refers to gems in a passage of dialogue:
"' ... Tell me, how are they cut, if they are so hard?'
'TI1e method would be difficult to explain to someone who had not seen it with his own eyes. As I have told you, it is done with the diamondpoint and with wheels of lead and emery: and some do it with a little bow ("archctto").' ""
The wording of the passage is somewhat ohscu.re. In particular~ the word "archett<( might refer either to a bow operating the spindle of the engraving-apparatus, or it might imply some sort of bow-shaped saw such as was in fact used to cut gems. What seems definite, hnwr·vcr is the usc of lead wheels and of emery

K Pazaurck, op. cit., interprets this ::V1S. as sho'Wing the "Paternostrer" giving his beads their ::;phcrieal form or perhaps 6nifihing pr polishing them ("Abdrehen von Rosenkranzkugeln'·'). He implies !.hat the heads arc of hardstone, but there is no evidence for this. A somewhat similar picture of a chaplet-maker in Venice in the 18th century shows very similar apparatus in usc for making: heads of what is dearly wood. Feldhaus, op. cit., interprets the "Paternostrer's" activity as that of entting his beads from the plank held in his lefl hand, by mean.<> of a multiple drilL This appears to eut a circular piece from the wood whilst at the same time piercing a central hole: no doubt the plank would then be turned and worked from the opposite side, 'l11is seems to make more sense than Pazaurek's interpretation.

as abrasive. combination Inight be used only for the plane-cutting of hardstones, but a late 15th century text, this time from Germany, fills Jn some detail which appears to point unequivocally to gem-engraving. This states that for gem-stone cutting a machine ("Gctczcugk"~"Zcug") is necessary, together with its five discs of lead, pewter, copper, steel and limewood.:~:{ This seems to imply interchangeable working-heads, ranging from the hardest (steel) to the softest limewood, for polishing.

propelling mechanism so far disbeen the bow-lathe. The earliest
form of this shows only the bow as the motive force, and it seems most likely that the bow was drawn first forwards and then backwards, to give a reciprocating motion. The addition of a flywheel might mean that when the spindle was set in motion in the one dircdion, the flywheel would sustain this impetus, the cord of the bow being then s]ackened and d:raV\JU back to its original position ready for a second thrust. There seems to be no evidence, however, that the bow-lathe with flywheel was in use in latemedieval the scene on which we must now focus our attention, since it was presumably there that the apparatus evolved which we shall later see in its developed form.

Lehmann's importance for the purpose of this article, however, is that in his person we see the gem- and glass-eng:ra vcr unmistakably united, the one function from the
other. His history justifies the inference tl1at the equipment of the glass-engraver was in all essentials that of the hardstone-engraver: and that where we cannot with certainty point to clear evidence as to the nature of the glass
engraver's tools at a given period, we may reasonably infer that it closely resembled those of the hardstonc-cngravcr at the same period.
This inference is borne out by a number of cross-checks at differe~t points.
The late 17th century print illustrated in Fig. 6 shows a glass-engraver at work,50 and al
though the artist has forgotten that the drivingbelt of the machine should pass below the level of the bench, what is shown above it seems reasonably well-observed. Here one may remark the "tower" of the apparatus, with the driving-pulley enclosed in a square structure, apparently equipped with two screws on either side and at the top. From the spindle projects the actual engraving-wheel, and numerous alternative wheels are seen on the table in front of the artist, who holds the tall-stemmed goblet in both hands to cngra vc it. On the table to his left arc two srnall containers) each with a la or the like resting in it. These no doubt con-

Tn this connection lhc name of Valentin Drausch rlesf'rves mention, although he is never referred to as more than a gem-engraver (Hol:.r.hausen, op. cit., pp. 91-3, 104-8, R 8-1.1). A perhaps even stronger candidate is Zacharias Peltzer (or Beltzer), whom Sandrart mentions as Lehmann's colleague in Prague and apparently also as an engraver of glass (op. cit., p. 316), and who was seal- and crystal-engraver to Maximilian of Bavaria from 1576-96 (Holzhausen, op. cit., pp. 94-5).

On the shelf and cupboard to his right stand further glasses, either finished or waiting their tum for decoration. Among them may be recognized types characteristic of Nuremberg, where tbis no doubt originated, and where the leading 17th century school of glassengraving was situated, The essential correctness of this print is confirmed by an achml surviving engraving-head preserved in the Museum at Liberec, in Czechoslovakia (Fig. 7).

One further ray of light is thrown by the apparatus preserved in Stockholm. With the

It is clear that even before the end of the 17th century the glass-engraver's equipment had been rendered sufficiently light and portable to enable it to be taken from place to place by vagrant glass-hawkers, who could then engrave on the the initials, coats-of-an:ns, etc. desired by their customers. The outstanding example of this phenomenon was the Bohemian Georg Franz Kreybich, who covered Europe from end to end with his barrow in the last years of the 17th century and the early of the 18th century. 68 Later evidence from Denmark has shown that the practice continued there until well into the 18th ccntury.69
It had been argued here that the sm·vi•cinP" engraving equipment and the written sources
authorize the assumption that the apparatus of the glass-engraver developed directly ou! of that of the hardstone-engraver. A difficulty arises, however, at this point. Joachim von Sandrart, writing in 1675 apropos Georg Schwanhardt, the pupil of Lehmann and the founder of the Nuremberg school of engravers, says: 70 ''Now although the previously mentioned artists brought glass-engraving to perfection, in so far as judgment and drawing were it was nevertheless impossib]e for them~ because of the all-too-powerful and clumsy tools which they used, to give delicacy or charm to their work; considering the still existing heavy apparatus and wheels (for which they had to employ assistants and wheel-turners, from whose midst thereafter sprang those still-flourishing weeds the 'Stimpler'") it is to be marvelled at that
