I want to know the answer to the following question:
When did Diodorus Siculus write Bibliotheca historica?
All the background I'm provided with is that "The most important source after Polybius is Diodorus Siculus who wrote his Bibliotheca historica between 60 and 30 BCE and reproduced some important earlier sources such as Hieronymus, but his account of the Hellenistic period breaks off after the battle of Ipsus (301).". Is that enough to answer the question?
Answer: yes
