How/Where do you get a solar tablet?

I've beat all Mech bosses bit now I'm stuck. How/Where do you get a solar tablet?


Solution 1:

Accroding to the Wiki they

[...] can be found in Lihzahrd Chests in the Jungle Temple.

and can also be made from Fragments which can be found from:

[...] in Lihzahrd Chests, and are dropped by Lihzahrds and Flying Snakes in the Jungle Temple.

and used at a Mythril or Orichalum anvil (the only two hardmode anvils) (Thanks @Aequitas)
