Unusually, have three unfinished clues this week, so hoping for some help with these.
8 down: light soft plain-weave cotton fabric, from Hindi 'eye's delight'
8 letters: * A * * S * O *
23 down: Athenian statesman & general instrumental in the Greek victories over the Persians at Marathon & Salamis; known as 'the just'
9 letters: A * I S * * D * S
26 down: Closing piece of music especially of an organ voluntary at the end of a church service
8 letters: P * * T * U * E
Very grateful to both who responded so quickly with the answers to my three queries. Having seen the answers, I'm not surprised I couldn't find the answers! I've always loved Greek history so I'll look up Aristides and find out a bit more about him.
