Many questions are coming up in class about the Myth of Ra, particularly regarding Ra's daily journey in the Solar Barge (a.k.a. Solar Barque, Sun Boat, Boat of 1000 Years). The following links are to websites with a wealth of information about Ra/Re and other Egyptian gods and goddesses.
One thing to keep in mind when studying Egyptian mythology is that the stories span thousands of years. A myth that explains, for example, the rising and setting of the sun would be associated with different deities at different time periods in Egyptian history. The qualities and attributes of one deity would often be absorbed later on into a different deity. That's why you will often see Ra's name together with the name of another god, like Amun or Horakhty.
