When the Moon rose in the Third Northern Hall I went to the Ninth Vestibule
ENTRY FOR THE FIRST DAY OF THE FIFTH MONTH IN THE YEAR THE ALBATROSS CAME TO THE SOUTH-WESTERN HALLS

When the Moon rose in the Third Northern Hall I went to the Ninth Vestibule to witness the joining of three Tides. This is something that happens only once every eight years.
    The Ninth Vestibule is remarkable for the three great Staricases it contains. Its Walls are lined with marble Statues, hundreds upon hundreds of them, Tier upon Tier, rising into the distant heights.
    I climbed up the Western Wall until I reached the Statue of a Woman carrying a Beehive, fifteen metres above the Pavement. The Woman is two or three times my own height and the Beehive is covered with marble Bees the size of my thumb. One Bee — this always gives me a slight sensation of queasiness — crawls over her left Eye. I squeezed Myself into the Woman's Niche and waited until I heard the Tides roaring in the Lower Halls and felt the Walls vibrating with the force of what was about to happen.

Piranesi by Susanna Clarke was published in 2020, and follows Piranesi, a man living in the House and its seemingly endless halls and vestibules. The House has an ocean, the likes of which can flood the lower halls, which Piranesi also uses as a source of food through its fish and other creatures.

The only other living occupant of the world is called the Other, a man seeking a Great and Secret Knowledge and with Piranesi's help is determined to find it within the House. They meet twice a week to discuss their findings and progress toward their goal.
