A tendency to assimilation of aspirated consonants, always avoided in literary Greek, is seen in such forms as [ΘΑΛΘΥΒΙΟΣ] for Ταλθύβιος, [ΧΑΧΡΥΛΙΟΝ] for Καχρυλίων, and [ΦΑΝΦΑΙΟΣ] for Πάμφαιος. The reverse tendency is curiously illustrated in [ΚΑΡΙΘΑΙΟΣ] for Χαριταῖος. Unassimilated forms occur, as in the case of [ΑΝΧΙΠΟΣ] for Ἄγχιππος.[2224] Another peculiarity is the omission of nasals before consonants, as in [ΑΤΑΛΑΤΕ] for Ἀταλά(ν)τη, [ΤΥΤΑΡΕΟΣ] for Τυ(ν)δαρέως,[2225] [ΙΑΦΥΙ] for Νύ(μ)φαι, [ΛΑΠΟΝ] for Λά(μ)πων, and [ΕΚΕΛΑΔΟΣ] for Ἐ(γ)κέλαδος. There is also a tendency to avoid double consonants, as in [ΜΕΣΙΛΑ] for Μνήσιλλα, [ΑΡΙΑΝΕ] for Ἀριάδνη, [ΚΛΥΤΑΙΜΕΣΤΡΑ] for Κλυταίμνηστρα, [ΠΕΡΟΦΑΤΑ] for Περσέφαττα[2226]; this is especially common in the case of double Λ or double Σ, as in [ΟΛΥΤΕΥΣ] and [ΜΕΣΙΛΑ] just quoted. On the other hand, on later vases consonants are often doubled without reason, as in [ΚΑΣΣΤΟΡ] for Κάστωρ,[2227] [ΤΡΙΠΠΤΟΛΕΜΟΣ] for Τριπτόλεμος, [ΜΕΜΜΝΟΝ] for Μέμνων, this being commonest with [fourline Σ] and [Π]. [Χ] and [Chalcidian Χ], originally absent from the Attic alphabet, are represented usually by [ΞΣ] and [ΘΣ], exceptionally by [ΚΣ] and [ΠΣ], as in [ΧΑΡΟΠΣ], [ΚΣΕΝΟΚΛΕΣ][2228]; also occasionally by metathesis, as [ΕΛΡΑΣΦΕΝ], [ΣΧΑΝΘΟΣ], [ΠΙΣΤΟΣΧΕΝΟΣ].[2229] Attic contractions, such as [ΧΑΤΕΡΟΣ] for καὶ ἕτερος and [ΚΑΜΟΙ] for καὶἐμοί, are also found.[2230] Among peculiarities of inflection (some of which may of course be mere misspellings) may be mentioned [ΗΥΙΥΣ] = υἱύς for υἱός, [ΠΑΥΣ] for paῖs, [ΘΕΣΥΣ] for Θησεύς, and [ΠΕΡΣΕΣ] for Περσεύς; also the open form -εες for -hς, as in [ΗΕΡΑΚΛΕΕΣ], [ΧΣΕΝΟΚΛΕΕΣ], and the form πίει for πίε; to some of these allusion has already been made. * * * * * From this mass of detail it is possible to deduce certain chronological results,[2231] which are not without their value for the dating of the various Athenian fabrics. Excluding the doubtful Dipylon vase, the inscriptions extend from the seventh century[2232] down to the time of Xenophantos and the late Panathenaic amphorae, a period of over three hundred years.
