Horus/Jesus isn't that close? Half the things in that image are totally made up. Gerald Massey has a lot to answer for.

Off the top of my head:

• Horus wasn't conceived of a virgin (his mother hovered over Osiris golden phallus to conceive him but it's not referred to as virgin conception anywhere)
• There are no three wise men in the story of Horus
• Christ wasn't born on December 25th, it was moved to coincide with the winter festival. Originally it was celebrated in July. Christianity doesn't claim that's Christ's birthday, it claims to celebrate it then. Nowhere in the bible does it state "December 25th"
• For that matter, neither was Horus. Horus' birth was during the Epagomenal Days which was a four day festival (of fertility, I believe) in the Egyptian calendar and it falls between August 24th and 28th. So I don't even know where they got that from
• His birth was not heralded by a star
• He was not taught in a temple as a child
• There is no such person as Anup the Baptizer. Best I can figure it's another name for Anubis but that also doesn't make any sense.
• Horus had four disciples. Later on he has 16 followers, and later still an unknown number join Horus for Mesnui (which was a large battle the details of which I cannot remember).
• Horus performed miracles, but he didn't walk on the water. All Gods perform miracles to demonstrate their divinity whilst they're among men. He also didn't raise anyone called El-Azur-Us from the dead.
• Not one of those names is accurate. Horus was called Avenger of his father, master of heaven, "great god" or "the great god" and a few others. The ones listed on your image are completely made up.
• Horus wasn't crucified (he was bit my a serpent sent by Set) but even if he was it doesn't mean he died on a cross. I found a good quote googling Crucifixion is the act of nailing, binding or impaling a living victim or sometimes a dead person to a cross, stake or a tree, whether for executing the body or for exposing the corpse. Thousands of people were "crucified" but very few were done on a cross - a growing number are now arguing that not even Jesus was. It tended to be people nailed to big wooden X's from what we can tell.

Ok so every single point in your image was wrong, I didn't realize when I started. Mithras/Jesus is a better comparison.
