I've begun scanning Horace and we don't get any references in class for scansion; our professor does it on the board and sometimes makes errors so it's hard for me to practice scansion when I do it and have no way to check it because sometimes, even when the meter fits according to quantity, something could be incorrect.
So my question has 2 faucets
1) Is there any book and/or online reference for the Scansion of common Horace poems?
2) In line 3 of Horace 1.5 (Ode to Pyrrha) do I scan something in Pyrrha as long? I'm struggling to find the third long syllable between grato and sub... Is the y in Pyrrha a vowel?
The line goes grato, Pyrrha, sub antro?
EDIT: This is completely in the wrong section I apologize, I didn't realize the forum had Greek and Latin: I clicked the "Learning X" forum I had been at before I registered my username. Could a moderator recity my mistake and move this to the Latin page?
