Daniel was a biblical figure in Human mythology.
History and specifics
One of the many stories atributed to this man involved God using Angels to protect Daniel from lions. In the Christian religion, this occasion marks the only use of Angels not sent to deliver a message or kill thousands. (TLE novel: Excelsior: Forged in Fire)
In the year 2285, before Rear Admiral James T. Kirk entered the Klingon mining facility on Magellan's World to talk to Captain Koloth, he told Doctor Leonard McCoy that walking into a lion's den worked for Daniel. (TOS comic: "Judgment Day!")
