The Great Greek Urn Caper

The Great Greek Urn Caper!

Hellooo, everyone!!
Now for more about our home school work. We have been doing some very exciting stuff we told you about earlier:

Let's start on the "Greek Urn Caper!!"

This book is about someone stealing a Greek Urn, and we must work out who stole it! We are given witness statements in English, but some of the words are in Greek lettering. We need to decipher the Greek words in order to eliminate suspects from our enquiries.

Here's the Classical Greek Alphabet:

α β γ δ ε ζ η θ ι κ λ μ ν ξ ο π ρ σς τ υ φ χ ψ ω
Α Β Γ Δ Ε Ζ Η Θ Ι Κ Λ Μ Ν Ξ Ο Π Ρ Σ Τ Υ Φ Χ Ψ Ω
 

That says:

Alpha

Beta

Gamma

Delta

Epsilon

Zeta

Eta

Theta

Iota

Kappa

Lamda

Mu

Nu

Xi

Omikron

Pi

Sigma (2 types)
