87. We may credit Julian himself, Orat. ad S P.Q.
Atheniensem, p. 279, sq., who gives a very particular
account of the transaction. Zosimus adds two hundred vessels
more, l. iii. [c. 5] p. 145. If we computed the 600 corn
ships of Julian at only seventy tons each, they were capable
of exporting 120,000 quarters (see Arbuthnofs Weights and
Measures, p. 237), and the country which could bear so large
an exportation must already have attained an improved state
of agriculture.
