[Leiden], not published, 1786. Oblong vellum leaf (32.1 x 41.8 cm). With original ink drawings, finely hand-coloured, of fifteen Dutch coats of arms.

A detailed, beautifully executed watercolour on vellum Ahnentafel with Dutch coat of arms, by the Dutch artist and engraver Johan Jacob Bijlart (1734-1809), also spelled Joannis Jacobus Bijlaert, Joannis Jacobus Bylaert, Jan Jacob Bylaerd, and Jan Jacob Bylaert, born in Rotterdam, but active in Leiden. Central in this work is a large coat of arms of the Van Winter family, joined, at its four corners, by the coats of arms (clockwise) of Van Winter, Van Beeckman, Van Hegh, and Van Wittich, and the shields of Van Alphen and Van Den Santheuvel. In the left (male) quarter are the four additional coats of arms, of the families Van Alphen, Van Musschenbroek, Van De Wall, Van De Water, and in the right (female) quarter are Van Den Sandheuvel, Orisant, Beljaartand Van Steelandt. Below, the Ahnentafel is signed and dated "J. J. Bijlaert fec': Anno 1786". These families were indeed genealogically connected in several ways. For instance, the great Dutch scientist Petrus van Musschenbroek (1692-1761), who invented the Leyden jar, was married on 16 July 1724 to Adriana van de Water (1694-1732). A few families are not part of nobility, viz., Beljaart, Orisant, Van Steelandt, and Van Wittich. Works by Bijlaert are in several Dutch museums, including the Rijksmuseum in Amsterdam.
