=Seals.=--These were closely connected with locks in ancient life, and often in fact took their place. Aristophanes makes the women complain that not only did their husbands carry the patent Laconian key, but that they also (at the instigation of Euripides) carried very complicated "worm-eaten" seals,[50] not likely to be forged. Several objects in this Case illustrate the use of seals. When a man wished to secure an object he tied it up with string and put a lump of clay over the knot, impressing the clay with his signet. Such impressions are seen on several baked lumps of clay here exhibited. One large lump (No. =451=) has no fewer than eight Roman seal impressions (several from the same seal), while the knot of the cord remains embedded in the clay underneath. This Case also contains examples (No. =452=) of Roman seal-locks (one in wood and several in ivory). The wooden lock, found in Egypt, is shown in fig. 191_a_, where its probable use is indicated. The lock was suspended from the door-jamb on a pivot passed through the small hole seen at the left end. The loop or staple attached to the door was then inserted in the groove, and the movable cover slid through it, as shown in the figure. The clay or wax was next pressed into the hole behind the lid, and sealed with a signet (as in fig. 191_b_, top view). The door could then not be opened unless the seal or the lock was broken. Such a lock would be very useful to prevent the often-mentioned pilfering by slaves.[51] Another interesting class of objects is that of the seal-boxes (No. =453=). They are small bronze boxes with hinged lids, and resemble in form a pear-shaped or circular lamp. Each box has a small slot cut out on either side, and three or four holes pierced in its floor. The cover not infrequently has a design in relief (such as might be impressed from a seal), _e.g._, a frog (fig. 191_d_). The illustration (fig. 191_e_) shows a suggested method of using them. The box is fastened by studs (passed through the holes in its floor) to the lid of the object to be secured. The string is inserted in a staple on the front of it and tied in a knot, which is placed in the seal-box and held fast by wax stamped with a seal. The projecting stud-heads would assist the natural tenacity of the wax, so that it would be impossible to remove the string without breaking the seal. Other arrangements are, of course, possible. For instance, the staple might not be used, and string might instead be tied round the object to be secured. The ends would be brought into the seal-box by two of the holes, there be secured by the sealed knot, and would leave it by two other holes. [Illustration: FIG. 192.--ROMAN CUTLER'S FORGE (NO. 457).
