Gabriel Grisley was a German physician, botanist, and chemist who is associated with founding a botanical garden in Xabregas, Lisbon, in the early 17th century. Your query appears to reference him and the Xabregas botanical garden, sometimes described as the Horto Real de Xabregas, and sources discuss Grisley’s role and works on medicinal plants and the flora of Portugal.

Biographical context

• Gabriel Grisley (sometimes rendered as Grisle or Grisli) is described in historical and bibliographic sources as having arrived in Portugal in the early 1600s and later establishing a botanical garden in Lisbon near Xabregas as part of royal support for botanical and medical knowledge. These sources discuss his medical, botanical, and chemical work and his publications on medicinal plants and Portuguese flora.

• The garden is often framed as a royal-backed initiative, reflecting early modern European interest in collecting, cataloging, and studying medicinal plants and local flora.

Geographic and historical notes

• Xabregas (Lisbon) is the neighborhood most frequently cited as the site of Grisley’s horticultural initiative, located near the Xabregas river area and in proximity to Lisbon’s urban expansion in the 17th century. Several academic references examine the probable location and historical context of the Horto Botânico de Xabregas.

• Contemporary scholarship often analyzes Grisley’s contributions within the broader history of botany in Portugal, including references to his published works on medicinal plants and the flora of Portugal.

Additional sources

• For a broader perspective on how early botanical gardens functioned in relation to medicine and teaching, see general discussions of botanic gardens and their herbal/medicinal plant collections in Europe; these provide useful context for Grisley’s era and pursuits.
