134. (1.) In some foreign proper names and in a very few Latin words the
quantity of a vowel varied. Vergil has #Sȳchaeus# and #Sychaeus# within
six verses; also #Āsia# and #Asia#, #Lavīnium# and #Lāvīnius#; so also
#glōmus# (Lucr.), #glomus# (Hor.); #cōturnīx# (Plaut., Lucr.),
#coturnīx# (Ov.).
(2.) Sometimes such variations in vowel quantity are only apparent:
thus, the occasional long final #-ē# of the active infinitive (#darē#,
#prōmerē#) has probably a different origin from the usual #-ĕ#. For
metrical lengthening, see 2505.
