read moreThree GREEK CROSSes = pairs of themers intersecting at their hidden Greek letters. The LAT published a bigger version of this concept just two weeks ago, unfortunately. I liked how that one crossed the same letter with itself, forming GREEK CROSSes with equal length arms.
But then I wondered, maybe John's done something brilliant by picking out Greek letters THAT SPELL OUT SOMETHING! That would more than enough make up for his unequal CROSS lengths.

ALPHA = A
RHO = R
IOTA = I
ZETA = Z
ARIZona? Maybe there are Greek artifacts in Tempe? This is actually happening!
OMEGA = O
THETA = T
Huh. Would you buy Judas IZcARIOT?
Humph.
The grid contains several rough spots, enough that I stopped keeping track after ANSE ALYN ARTE RIAL SECY. Five strikes and you're out for an early-week puzzle! (That number could easily be three or less, for some solvers.) Not nearly smooth enough to be accessible to newer solvers.
What happened? The biggest problem is the size of the real estate around each pair of crossing letters. Take FINAL PHASE and AIR HOLES, for example. It's usually wise to put a black square close to that intersection, probably at the first P of PPM. If you don't, you're effectively trying to build a themeless-esque grid — but with several constraints already locked into place.
There's no easy fix, unfortunately, since if you put a black square at the first P of PPM, you'd form a two-letter word. That means you'd need to move that black square to the left of LEMON ZEST. The shocks ripple through the puzzle, and require a full redo. Unfortunate, but that's what was necessary.
I did like that John managed to work in so much snazzy long fill. LEMON ZEST and REST EASY are welcome surprises in the middle of the puzzle. LEAD APRONS, RAMS HORN, and PIT AGAINST would have also added to the quality of my solving experience, except for the problems they caused in short fill.
