There is no sharp distinction between Old Latin, as it was spoken for most of the Republic, and Classical Latin, but the earlier grades into the later. The end of the republic was too late a termination for compilers after Wordsworth; Charles Edwin Bennett said, "'Early Latin' is necessarily a somewhat vague term ... Bell, "De locativi in prisca Latinitate vi et usu", Breslau, 1889, sets the later limit at 75 BC. A definite date is really impossible, since archaic Latin does not terminate abruptly, but continues even down to imperial times." Bennett's own date of 100 BC did not prevail but rather Bell's 75 BC became the standard as expressed in the four-volume Loeb Library and other major compendia. Over the 377 years from 452 to 75 BC, Old Latin evolved from being partially comprehensible by classicists with study to being easily read by scholars.
