Great value seems to have been set upon the painted vases by their possessors. When broken, they were repaired by the pieces being skilfully fitted and drilled, with a rivet of lead or bronze neatly attached to the sides. Several mended vases exist in the European collections.[490] Occasionally they were repaired by inserting pieces of other vases. Thus a vase with two handles, found at Vulci, of the shape called στάμνος, is repaired with a part of a kylix representing quite a different subject, and thus presents a discordant effect.[491] A R.F. vase in the Louvre has actually been mended with part of a B.F. vase.[492] A B.F. kylix in the British Museum (B 398) has a piece inserted with the name of Priapos; similarly the two handles of the R.F. kylix E 4, with the signature of Thypheithides, do not belong to the vase; but these may both be modern restorations. The large casks of coarse and unglazed ware (πίθοι) were also repaired with leaden cramps. “The casks of the ill-clad Cynic,” says the Roman satirist, “do not burn; should you break one of them, another house will be made by to-morrow, or the same will continue to serve when repaired with lead.”[493] Aristophanes puts into the mouth of his old litigant turned _roué_ a popular story of Sybaris which alludes to the use of bronze rivets. A woman of that city broke an earthen pot, which was represented as screaming out, and calling for witnesses to prove how badly it had been treated. “By Persephone!” exclaims the dame, “were you to leave off bawling for witnesses, and make haste to buy a copper clamp (ἐπίδεσμον) to rivet yourself with, you would show more sense.”[494] * * * * * After noting the chief uses of Greek vases it is necessary to give some account of the different shapes, and to identify the recorded names as far as possible with the various kinds actually found. The subject is, however, one of great difficulty, and it is impossible to attain to scientific accuracy, owing to the differences of time between the authors by whom they are mentioned, the difficulty of explaining types by verbal descriptions, and the ambiguity often caused by the ancient practice of describing a vase of one shape by the name of another.
