looking for a magic item that grants spells known

[Yaba]

I tried searching, but came up empty. Is there a published magic item for Pathfinder that (temporarily) adds one or more specific spells to a spontaneous caster's list of known spells?

Page of Spell Knowledge

This page is covered in densely-worded arcane or divine magical runes. It contains the knowledge of a single arcane or divine spell (chosen by the creator when the item is crafted). If the bearer is a spontaneous spellcaster and has that spell on her class spell list, she may use her spell slots to cast that spell as if it were one of her spells known. A page of spell knowledge is priced based on the spell's cleric or sorcerer/wizard spell level, unless the spell doesn't appear on either of those spell lists, in which case it is based on the highest spell level as it appears on any other spell list. For example, a spell that is on the 4th-level inquisitor list and the 2nd-level paladin list is priced as a 4th-level spell.

Slot none; Price 1,000 gp (1st), 4,000 gp (2nd), 9,000 gp (3rd), 16,000 gp (4th), 25,000 gp (5th), 36,000 gp (6th), 49,000 gp (7th), 64,000 gp (8th), 81,000 gp (9th)

Cracked Orange Prism and Ring of Spell Knowledge let you add spells to your spells known, including off list ones.

Cassock of the Clergy gives an extra cantrip, but is pretty useless for that purpose, being much more expensive than the Prism, using a slot and its additional functions not being very useful, especially for a divine caster who can use those spells anyways.
