Not too hard today, however can someone provide me with a explanation for 27a. My answer is indeed a roman or greek portico, the "13: 60-1" in the clue has baffled me.
Good evening strummer,
Is it not that you "school" (re-order) the letters of the word for 60, taking away (-) the letter for the figure 1?
Yours circumspectly!
