From your wiki link, which fails to state that Calvin burned Sevectus, not *Servectus*.
When Calvin requested that Servetus be executed by decapitation as a traitor rather than by fire as a heretic, Farel, in a letter of 8 September, chided him for undue lenience.[34] The Geneva Council refused his request. On 27 October 1553 Servetus was burned at the stake just outside Geneva with what was believed to be the last copy of his book chained to his leg. Historians record his last words as: "Jesus, Son of the Eternal God, have mercy on me."[35]

I got the following message..."The requested document does not exist on this server. "

An independent source? A blog? Dan who? Still fails to show that Calvin did the deed.
Hat trick fail.
I won’t waste my breath.
