What is in this image? Describe it as if you were explaining it to someone from the 15th century.

This image depicts a large structure, much like a floating fortress, resting on its side in the water. Though it may resemble a great ship, its form is quite unusual. It has multiple large, cylindrical protrusions extending from one side, suggesting it might house mechanisms far beyond the comprehension of our current age. It has a number of windows or circular openings along its sides, which might serve as watch points or air intakes for internal chambers. The mast that typically rises from the top of a ship here lies along its length, supporting the idea that this vessel is portrayed in an unconventional orientation. The name "Albatross" is etched onto its side, possibly suggesting it bears the resilience and far-reaching capability of the seabird known for its extensive and enduring flights across the seas.
