A number of Greek names encountered in hexameter follow the syllable length pattern
-vv-; consider for example Penelope, Telemachos, Calliope, Terpsichore.
-v-- is absent as the metric would not permit it, but I find it hard to believe that Greek names would completely avoid this pattern.
This is not the only name pattern in hexameter, but just an example.
There are also a number of names that do not fit, like the pattern
-v- of Socrates.
What did metric constraints do to names? How did the names in poetry end up so convenient for hexameter?
I can think of a couple of options:
- There were a number of names, and only the ones fitting the pattern were used. This would lead to name changes in works like the Iliad which mention a huge number of names.
- The names were adapted to the metre. Perhaps the original forms of the names were incompatible with hexameter but they were massaged into a variant that fits. This could be supported by citing examples of such variants.
- The names were created for poetry in the first place. Then the names all come in a suitable pattern, but they cannot come from earlier non-hexametric myths.
- We just do not know why the names are so convenient metrically.
Of course, it could be any combination of these. It is possible that there is no full answer out there, so any partial insights would be welcome answers.
