23a All I can think of is Vasari, an artist who designed and started to build the Uffizi. Are you sure of your S?

For 3d, John (Jack?) Masefield's 'Sea Fever' looks promising but I can't see the connection to the second 'jack'. Neither can I see why SANDS for 1a and SELLOTAPE for 28a. I've already voiced my concerns about SAGA (19a) elsewhere. I'm obviously struggling with what, to others, are obvious answers.

I presume the second Jack is the sailor narrating the poem.

Belated thanks to all and answer to slaney: the 'S' comes from SATAN Continue to play with a name for Bronte. Only thing I could think of, but a bit thin even for TLS.

Continue to play... ACTON (Bell) act on
