これまた

[thetazuo]

それは、大きな作業机であった。様々の画材が所狭しと並び、これまた大きな蛍光灯が机の全面を照らすように設置されている。

Hi. Just a simple question. What does this これまた mean exactly?

Thank you.

I think その上 or さらに加えて closely resemble this usage here.

 

[NyMedic1960]

これまた is a short form of これはまた, meaning 意外な物事や、人の思わない動作やことばに驚いたときに発する語, i.e. interjection used to describe unexpected surprise.

This is my quick translation.
That was a grand work table which was cluttered with all sorts of painting tools that were covering the entire surface; and then, there was also a huge fluorescent light which was positioned in a way that it illuminated the entire surface of the table.
　I hope it is good enough.
