Thanks, to keep with the Victorian tradition of invoking ancient mythology, the two ladies in the logo are Pheme, Greek goddess of News, Announcements, and Gossip. She is portrayed as blowing a trumpet. The other is Seshat, the Egyptian goddess of scribes and record keeping, holding a plume (large quill). I was reading through an 1810 book on hermeneutics written by a Pastor/Theologian and it really hit home how knowledgeable the 19th century person was in Biblical and ancient mythological references.
