Thor was usually portrayed as a large, powerful man with a red beard and eyes of lighting.  Despite his ferocious appearance, he was very popular as the protector of both gods and humans against the forces of evil.  He even surpassed his father Odin in popularity because, contrary to Odin, he did not require human sacrifices.  In his temple at Uppsala he was shown standing with Odin at his right side.  This temple was replaced by a Christian church in 1080.
