Variants and attestation
The most prevalent form of Kappa is one with full-length bars meeting in the middle. Forms with shortened bars occur sporadically all over the Raetic area; sometimes consistently in one inscription, but also mixed (e.g. IT-5). The very similar variants and are distinguished on account of the fact that the former occurs exclusively in a certain type of petrograph (see Raetic epigraphy). This is also the case for rounded K5 s (cp. the frequency of rounded forms of Alpha and Upsilon in rock inscriptions).
