Cato id saepenumero attestatus est, Gell. 4, 12: attestata fulgura, in the lang. of omens, lightnings which confirm that which was indicated by previous lightnings, confirmatory (opp. peremptalibus, which cancel, annul, what was previously indicated): attestata (fulmina), quae prioribus consentiunt, Sen. Q. N. 2, 49: attestata dicebantur fulgura, quae iterato fiebant, videlicet significationem priorum attestantia, Paul. ex Fest. p. 12 Müll.; cf. Müll. Etrusk. 2, p. 170.
