Athens, to whom Olynthus appealed, sent no adequate forces, in spite of the upbraidings of Demosthenes (see his Olynthiacs), and in the spring of 347 Olynthus fell.
Thomas Wilson, in the epistle prefixed to his translation of the Olynthiacs of Demosthenes (1570), has a long and most interesting eulogy of Cheke; and Thomas Nash, in To the Gentlemen Students, prefixed to Robert Greene's Menaphon (1589), calls him "the Exchequer of eloquence, Sir Ihon Cheke, a man of men, supernaturally traded in all tongues."
They are documents, as indispensable as the Olynthiacs or Philippics, for his own political career.
The First and Second Olynthiacs of Demosthenes were spoken in that year in support of sending one force to defend Olynthus and another to attack Philip. "Better now than later," is the thought of the First Olynthiac. The Second argues that Philip's strength is overrated.
