Richard Alpert - Egyptian
Richard Alpert was an Egyptian priest or pharoah when he came to Craphole Island. Also, he was dead. Mummified. But he awoke when he entered Craphole Island…much as Locke has. Re-born…which explains the Anubis worship a bit more. And the whole unaging immortal thing.
Also, Richard Alpert’s initials are R and A. RA. Ra is the Egyptian god of the sun. Hmmm…
