SUMMARY:Arnoldia Spotlight: Reading the Landscape as Historical Text
DESCRIPTION:This program has been cancelled. \n\n\n\nThis is a members-only program. Not a member? Click here to join. \n\n\n\nBefore this landscape became an Arboretum\, part of it belonged to a black landowner and farmer named Simeon Giles. A Harvard seminar called Slavery\, the Environment\, and Public History explored what we can learn about Giles and his family by reading the landscape today: which of the trees here were present at that time? What would Giles have cultivated here\, and how might the lay of the land have impacted his livelihood? Harvard graduate student Riley Sutherland wrote an article in the summer feature of Arnoldia describing the course and what they learned\, and she will be heading out into the landscape again along with Horticulturist Brendan Keegan and Arnoldia Editor Matthew Battles to share what they learned about Giles\, the history of this land\, and the stories landscapes tell. \n\n\n\nAccessibility: This program involves traversing moderate hills\, uneven ground\, and dirt paths. \n\n\n\nAudience: This members-only program is geared towards adults. \n\n\n\nInclement weather policy: Participants will be notified via email at least one day in advance if a program needs to be cancelled due to inclement weather\, and will be notified by phone if a program must be cancelled with less one day’s notice. Click here to view our full inclement weather policy. If you have questions about the status of a program\, please email publicprograms@arnarb.harvard.edu (inbox monitored on weekdays) or call the Visitor Center desk between 10:00am and 4:00pm at (617) 384-5209.

SUMMARY:The Cosmic Tree: A Universal Symbol of Life: Flowering Trees
DESCRIPTION:Cosmologies are ways of understanding the nature of the universe\, of experiencing the world in all its variations including the visible and the invisible. Over millennia trees have served as the mythological archetype of the world’s axis (axis mundi)\, the pole through the earth’s center which connects the worlds above and below. Within a cosmic-magical model of the world  (imago mundi)\, trees also evolved in various cultures to possess innate spiritual powers or as conduits for communication with the holy or sacred. \n\n\n\nDuring this tour we will discuss angiosperms\, the largest and most diverse group in the plant kingdom. All flowering trees are angiosperms\, but not all angiosperms reproduce in the same way\, so you may not see blooms and flowers but plenty of leaves. Docent Katrina Scott will lead this interactive tour with stops for moments to reflect on specific trees and the stories associated with them. Were they revered or feared?  A home for deities or tricksters?  We will begin at the Center Street Gate starting at Jack Dawson’s shagbark hickory (1883) then head up Oak Path to Beech Path ending at Bussey Hill Road after visiting the ash trees of Norse mythology (Yggdrasil.). \n\n\n\nAccessibility: This walk will include woodchip and gravel paths. Please wear long pants and closed toe shoes and bring a cloth/towel/mat for sitting/lying down. \n\n\n\nAudience: This program is geared towards adults. \n\n\n\nWeather Policy: Tours will be canceled in cases of the following weather conditions: severe wind\, snow\, ice\, thunder or lightning events; temperatures over 90 degrees; and temperatures below 20 degrees. Tours may be canceled due to other weather events at the discretion of Arboretum staff. In the case of cancelation\, you will be contacted by Arboretum staff no later than 2 hours before the start of the event.
