Storyline

When the planet Sarpeidon is about to be destroyed, by its star Beta Niobe becoming a supernova, Kirk (William Shatner), Spock (Leonard Nimoy) and McCoy (DeForest Kelley) beam down and find it evacuated except for its librarian, Mr. Atoz (Ian Wolfe), tending to his replicas. They are a collection of unusual discs, which play the planet's history and (to their surprise) allow their users to travel into the past through the atavachron, a time machine, into the periods each was studying on disc. The crew travels unprepared, McCoy and Spock find themselves locked in a frozen ice age 5,000 years ago, where Spock reverts to the barbaric age of the Vulcans. He becomes very easily agitated, and is intensely attracted to the political prisoner Zarabeth (Mariette Hartley), who enjoys getting company but tells them return is impossible. Kirk arrives in a Cromwellian period, where he's arrested and suspected of witchcraft. He soon realizes the magistrate must be a time traveler like him, and ... Written by KGF Vissers

Trivia

Mariette Hartley (Zarabeth) was not allowed to show her belly-button in this episode, despite the appearances of other women's navels in previous episodes. To comment on this censorship, Gene Roddenberry gave Hartley's character two navels in his pilot Genesis II (1973), stating that "the network owed me one." See more »

Goofs

Spock tells Zarabeth that he comes from a place "millions" of light-years away. The Milky Way is approximately 100,000 light-years in diameter - so "millions" of light-years would place Vulcan well outside the galaxy. This may be a sign of the dementia he suffers as a side-effect of time travel. See more »

A Supernova and A Time Portal Into Sarpeidon's History
14 January 2017 | by Rainey-DawnSee all my reviews

Season 3, episode 23. The Enterprise goes to the planet Sarpeidon to help the people before their sun becomes a supernova. Ship's scanners indicate there is no life on the planet. Kirk, Spock and McCoy beam down to investigate and run across one life, the librarian Mr Atoz. Mr Atoz scolds them for being very late. Atoz knows about the supernova and shows them the Atavachron, a time portal which he will escape into to be with his family. A woman screams and Kirk, by instinct, runs through the portal to save her, followed by McCoy and Spock while Mr Atoz yells at them to wait because they are not prepared. Kirk ends up in a place that is much like Earth's England in the 17th century. McCoy and Spock end up in the Sarpedidon's ice age. None of the 3 men can find the portal back to where they came from but they can hear one another from the area they stepped into. Spock is correct in speculating that all of the inhabitants (outside of Mr Atoz) has escaped the danger of the supernova by going into the planet's history. Now the 3 must find a way back to their own time and the Enterprise.

Excellent episode that proves that season 3 is not nearly as bad as some have tried to make it out to be. This one is quite memorable and still has a place in my heart from my teen years.

9.5/10
