 Horace does the same, referring to "Babylonian horoscopes" rather than Chaldean in his famous Carpe Diem ode.Cicero views the Babylonian astrologers as holding obscure knowledge, while Horace thinks that they are wasting their time and would be happier "going with the flow".The terms Chaldee and Chaldean were henceforth only found in Hebraic and Biblical sources dating from the 6th and 5th centuries BCE, and referring specifically to the period of the Chaldean Dynasty of Babylon.
