Diogenes
12. Of RHODES, a Greek grammarian, who used to hold disputations at Rhodes every seventh day. Tiberius once wanted to hear him; but as it was not the usual day for disputing, the grammarian bade him come again on the seventh day. Afterwards Diogenes came to Rome, and when he asked permission to pay his homage, the emperor did not admit him, but requested him to come again after the lapse of seven years. (Suet. Tib. 32.)
