What is "haerlempjes"

Haerlempjes refer to a specific genre of landscape painting that includes a view of Haarlem (formerly spelled Haerlem). It is used most often to refer to Jacob van Ruisdael's panoramic views of the city, but the term is derived from mentions in Haarlem archives as a type of painting included in household inventories. The diminutive suffix "pje" would denote a small, cabinet-sized painting, but even the largest landscapes may be referred to as Haerlempjes today.
